Kuvings B6000S and C7000S Juicer Review | 2022

Pros

• Greatest asset is its 3 in. wide chute – less cutting of produce is required than what is normally the case for a slow juicer
• Wide chute and vertical design makes the actual juicing process take a much shorter amount of time that what is normally the case for a slow juicer
• Extracts a juice that’s virtually pulp-free
• Extra cleaning tools make this juicer very easy to clean
• Stain resistant parts make it highly resistant to staining over time
• Great versatility for a vertical slow juicer – an additional blank strainer is included and a smoothie strainer can be purchased separately
• Made of very high quality parts, comes with a long 10 year warranty, and it’s very easy to claim that warranty if needed

Cons

• A poor option if you’re looking for a juicer that is able to obtain maximum yields – this juicer obtained only average to below average yields in most of our tests
• Not a very good option if you’re looking for a good value – the juicer’s poor performance means that you’ll get less bang for your buck (less juice) out of a given quantity of dry produce

Model Notes

In 2016 Kuvings released an update of the Kuvings B6000S Whole Slow Juicer, aptly called the Kuvings C7000S Whole Slow Juicer Elite. Differences between the B6000S and C7000S are listed below.

Smart cap – the old model’s smart cap has a black plastic finish. The new model’s smart cap has a chrome metal finish. In our opinion, this is much more of a downgrade than it is an upgrade. We tested a few different juicers with shiny metal finishes and all of them were difficult to clean or at least keep looking clean. Why? Because a shiny metal surface such as chrome attracts smudges and shows the tiniest little speck of dirt or oil (even the oil from your hands) much more so than plastic does. Sure, the new cap may look great after it’s been painstakingly cleaned and kept smudge-free in a studio for the purpose of taking product pictures. But in an environment in which the juicer is actually used – an environment in which juice might get onto the cap and would have to be cleaned off – the cap could very easily be the worst looking part of the juicer if it hasn’t been properly cleaned and inspected to make sure that it is in fact smudge-free. We don’t like any juicer feature that benefits a juicer’s aesthetic at the cost of it making the juicer more impractical to use on a regular basis. This is one such feature and one that we wish Kuvings didn’t implement on the new design.

Juicing bowl – the old (B6000S) juicing bowl employed the use of a removable silicone seal at its center to keep its contents from leaking onto the main body of the juicer. The new (C7000S) juicing bowl still employs a rubber seal for this purpose but it is not removable. The manufacturer claims that the new design is an upgrade that makes the juicer easier to assemble and clean because it makes for one less part to assemble and clean. The truth is that we didn’t remove its juicing bowl seal even once when we tested the B6000S as we didn’t find that it was necessary to do so to clean it. This makes this new design not so much of an upgrade as it simply is well, a new design.

Auger – the new auger “is designed to reduce pulp in extracted juice” according to the manufacturer. Truth be told that the B6000S introduced less pulp into the juice it extracted than most other slow juicers we tested – hence why it received an almost perfect 4.5 out of 5 score in the pulp-free review category. In other words, the introduction of excess pulp into extracted juice was not a problem for this juicer when we tested it. This makes this apparent upgrade of very little consequence, at least according to our own experience (and the accompanying test data) using the previous model.

The paragraphs above demonstrate the following two points: First, the C7000S is much more of a refresh of the B6000S than it is an entirely new model. Very few parts have been impacted by this refresh and those parts that have been “updated” have seen very minor changes. Second, those changes that have been implemented either do nothing or very little to improve the juicer’s performance.

Now, since very few changes have been made with the release of the C7000S and because all of those changes are likely to have very little impact on the actual performance, cleaning difficulty, versatility, value, etc. of the juicer we have decided to forego testing it at this time. Instead, we believe that our testing of the B6000S properly represents what we would hypothetically observe testing the C7000S. And as such, the review we’ve written for the B6000S should serve just as well as a review for the newly released C7000S. If you’re torn between only these two models our recommendation would be that you purchase whichever model you can find at a lower price. If you want to know how either model compares to other juicers on the market and how its specific attributes affect its assembly difficulty, ease of use, and performance among other things, our review below should serve to cover both the B6000S and C7000S equally well.

In summary

We tested the B6000S but not the C7000S. Regardless, there are so few differences and such minor differences between them that our testing of the B6000S is applicable to the C7000S as well. Hence, the review we’ve written for the B6000S below, applies just as well to the C7000S.

Additional color notes

A red and white version of the B6000S is also available. The red version has the model name B6000PR and the white version has the model name B6000W. Note that despite having different model names, these two versions of the B6000S are identical to it except for the color of their bodies.

Assembly

The Kuvings whole slow juicer (and whole slow juicer elite) can not only be used in a conventional manner to make fruit and vegetable juice, but it can also be used to make sorbets, smoothies, nut butters, nut milks and baby food. Let’s first take a look at the parts required to assemble the juicer for its primary purpose – juicing.

Juicing – Parts List

1. Food pusher
2. Feeding chute assembly (feeding tube and drum lid)
3. Juicing bowl
4. Juice cap (smart cap)
5. Spinning brush (rotation wiper)
6. Juicing strainer
7. Auger (juicing screw)
8. Main body (base)
9. Juice container (pulp cup)
10. Pulp container (juice cup)

The general terms we use for vertical masticating juicer parts are listed. If Kuvings calls a certain part by a different name in the user manual included with the juicer it is listed in parentheses.

Making nut milks – Parts List

The Kuvings B6000S (and C7000S) can also be used to make a wide variety of nut milks including soy milk, almond milk, and cashew milk. In order to use the juicer to make homemade nut milks, the exact same parts are used and are assembled in exactly the same way as the parts used for juicing. The procedure for making nut milks usually involves first soaking the nuts in water for several hours, then feeding the nuts and pouring water in equal parts into the feed chute of the juicer. The final step involves straining the processed nut/water mixture into a glass or container – the resulting mixture is milk.

Other Applications – Parts List

1. Food pusher
2. Feeding chute assembly
3. Juicing bowl
4. Juice cap
5. Spinning brush
6. Blank strainer OR smoothie strainer
7. Auger
8. Main body
9. Juice container
10. Pulp container

Notes

In order to assemble the juicer for any application other than juicing or making milk, simply replace the juicing strainer with either the blank strainer or the smoothie strainer. Note that while the blank strainer is included with your purchase the smoothie strainer will need to be purchased separately. Both strainers are very close to the same dimensions and shape as the included juicing strainer so they fit into the spinning brush within the juicing bowl exactly the same way that the juicing strainer does – we discuss this part of assembly in detail below.

When using the smoothie strainer, processed food exits the juicer exactly the same way as it does when juicing with the juicing strainer – through both the pulp outlet and juice outlet. However, when using the blank strainer processed food exits the juicer only through the pulp outlet and so, when using the blank strainer, you won’t need to place a juice container under the juice outlet and neither will you find it necessary at any time to use the juice cap.

The blank strainer is used to make fruit sorbets, gelatos, and ice creams. The smoothie strainer, purchased separately, is used to make fruit smoothies and pureed baby food. Note that the included recipe book will show you exactly how to make everything we just mentioned except for pureed baby food.

Extra Removable Parts

In addition to the parts listed above, several other smaller but no less important parts can be removed (and eventually replaced) should you want to go the extra mile and fully disassemble the juicer for cleaning. We did not find during testing that it was absolutely necessary to do so – to remove these parts for cleaning and therefore replace them for assembly – and so we’ve put them in a separate list below.

1. Silicone blades
2. Silicone pulp pressure plug
3. Sealing ring
4. Juice cap seal

The Spinning Brush and Its Silicone Blades

The juicer’s spinning brush is composed of three silicone blades that fit into a plastic frame. All three blades can be removed from the frame for cleaning although we didn’t find it necessary to do so during our testing of the juicer. Yes, you could certainly remove each blade to clean it as a separate part but you could also clean it just as well while it is still fitted to the frame, at least according to our own experience cleaning the juicer during testing.

The spinning brush is fitted inside the juicing the bowl so that it’s positioned directly between the juicing strainer and the inside walls of the juicing bowl. It is fitted in such a way that its silicone blades are in direct contact with the walls of the juicing bowl. The silicone blades are not only wide enough to reach out to and make contact with the walls of the juicing bowl, but long enough to reach from the bottom to the very top of the juicing bowl. A series of gears rotate the spinning brush. The bottom of the spinning brush has teeth that are fitted to a gear located on the bottom of the juicing bowl. This gear’s teeth are in direct contact with teeth on the bottom of the auger. When the juicer is turned on and the auger rotates, it turns the gear on the bottom of the juicing bowl, which turns the spinning brush. In this way, the spinning brush is constantly rotating at the same speed as the auger.

The spinning brush has two basic purposes. One, it serves to self-clean the juicer. And two, it serves to move juice from the bottom and sides of the juicing bowl to the juice outlet where it exits the juicer. When a particular piece of fruit or vegetable is fed into the juicer’s feeding chute it falls down or is pushed down by the food pusher right on top of the auger. The auger’s grooves pull the piece of produce to the bottom of the juicing bowl. On its way down the produce is crushed against the inside walls of the juicing strainer. This is how juice is made. The dry fibrous part of the produce continues to be pulled all the way down to the bottom and center of the juicing bowl where it exits through a small hole into the pulp outlet. The liquid part of the produce – the juice – collects on the outside of the strainer where most of it falls down to the bottom and outside perimeter of the juicing bowl. Not all of the juice simply falls to the bottom by gravity. The crushing and straining process sometimes results in some of the juice spraying against the inside walls of the juicing bowl. This is where the spinning brush functions to self-clean the juicer. Its silicone blades wipe the inside wall of the juicing bowl clean. It thereby also serves to move juice that would otherwise accumulate on the wall of the juicing bowl down to the bottom outside perimeter of the juicing bowl. At the same time, it moves this juice in addition to the juice that’s fallen down from the strainer by gravity from the bottom outside perimeter of the juicing bowl out through the juicing bowl’s juice outlet.

The Silicone Pulp Pressure Plug

The juicer’s pulp pressure plug is located on the bottom of the juicing bowl. One end of the plug is semi permanently attached to the bottom of the juicing bowl while the other end plugs into the “back side” of the pulp outlet. This “back side” entry to the pulp outlet is only accessible from the bottom of the juicing bowl. The “front side” of the pulp outlet is the clearly visible end from which pulp exits out of the juicing bowl and into the pulp container. There’s also a “top side” to the pulp outlet. This is the end from which dried pulp first enters the pulp outlet from the juicing bowl. It’s only visible by looking into the juicing bowl from an overhead perspective.

To clarify, the pulp outlet is essentially a rectangular chute with three open ends. The first open end, the “back side” of the pulp outlet, is the end that can be plugged or unplugged by the pulp pressure plug. The second open end, the end that we refer to as the “front side” of the pulp outlet, is the end from which dried pulp exits the juicing bowl. The third open end, what we refer to as the “top side” of the pulp outlet, Is the end into which pulp enters from the juicing bowl into the pulp outlet.

In any case, it’s important to note that the juice outlet could function without issue with only two open ends, those being the “front side” and the “top side”. If this were the case pulp would be able to enter into the pulp outlet from the “top side” exactly the way it does now and exit the pulp outlet through the “front side” end exactly the same way as it does now. A pulp outlet with only two open ends would in fact work absolutely flawlessly for juicing.

The problem that makes the third open end and the pulp pressure plug necessary is pulp accumulation within the pulp outlet itself. After juicing even a small quantity of produce, not all of the generated dried pulp moves completely through the pulp outlet and into the pulp container. As much dried pulp as can fit inside the pulp outlet stays behind inside of it. This problem cannot be remedied by pre-washing. The only way to clean out this left over pulp is by either pulling or pushing it out of the pulp outlet by hand.

Back to the hypothetical scenario in which the juice outlet has only two open ends: these would be the only two ends from which the pulp outlet can be accessed for cleaning. The problem is that while the “front side” end of the pulp outlet is large, the “top side” hole is very small. In addition, the “front side” and “top side” ends of the outlet are not directly opposite of each other. Under these conditions – with the pulp outlet only having these two open ends – cleaning it out without a specialized tool would be very difficult.

The solution to this problem is to add a third end to the pulp outlet chute, one that is just as large of a hole as the “front side” hole and directly opposite it, and this is just what vertical masticating juicer manufacturers have done in designing this specific type of juicer. Now you’re able to push a hard object such as the handle of the cleaning brush directly through the pulp outlet for cleaning. This allows you to push the collected dried pulp out of the outlet much more easily. When rinsing the pulp outlet, the water is now able to move in a straight line through the outlet, giving it a greater velocity through the outlet, which enables it to wash the inside of the outlet much better than it would be able to otherwise. When you’re done cleaning simply plug the pulp pressure plug back in and the juicer is once again able to function exactly as it should for juicing, with only two open ends.

The Sealing Ring

At the bottom center of the juicing bowl is a hole. This is the hole through which the juicer’s motor shaft extends upwards from the main body of the juicer and into the interior of the juicing bowl. Because the juicing bowl is made of a hard plastic and the motor shaft is made of metal, even direct contact between the two would not result in a waterproof seal – a seal that is absolutely necessary for juice to not leak out of the juicing bowl and onto the main body of the juicer. This seal is provided by a silicone sealing ring that fits inside of the juicing bowl and snugly around the motor shaft.

The sealing ring can be removed from the juicing bowl for cleaning but we did not find it necessary to do so during our testing of the juicer.

The Juice Cap Seal

The same way that the juicing bowl requires a silicone sealing ring to provide a water tight seal between it and the main body of the juicer, so does the juice cap require a silicone seal to provide a water tight seal between it and the juice outlet.  Like the sealing ring it is fully removable. However, like the sealing ring, we also did not find it necessary to remove this seal for cleaning during our testing.

Assembly Introduction

Assembling any masticating juicer is a fairly complex process, at least when compared to the assembly of most other kitchen appliances. As such, we discuss the Kuvings whole slow juicer’s assembly in detail further down below.

It is of note that the B6000S (and C7000S) is composed of all of the same parts that make up every other vertical masticating juicer we tested, with the exception of the juice cap which was absent on the Breville BJS600XL and Omega VRT350. In any case, most of the parts are exactly the same and so they fit together exactly the same on all of the vertical masticating juicers we tested. Why and how then, can we say that one vertical masticating juicer is more difficult to assemble than another?

Markers and Guides

The biggest factor that distinguishes the difficulty of assembling one vertical masticating juicer compared to another is how well the manufacturer has implemented markers and guides on the parts that are put together when assembling the juicer. Assembly of a juicer of this type can be broken down into five basic steps

1. Fitting the juicing bowl to the main body.
2. Fitting the strainer inside the spinning brush.
3. Fitting the strainer and spinning brush to the juicing bowl.
4. Fitting the auger inside the juicing bowl.
5. Fitting the feeding chute assembly to the juicing bowl.
6. Making sure that everything else is ready for juicing – juice container and pulp containers are placed under their respective outlets and food pusher is nearby.

Steps 1 through 5 are of course the most difficult. The sixth step is really not so much a part of assembly as it is an extra step that we felt should be mentioned as it does take some time and it is absolutely necessary to complete before juicing (you don’t want to make juice and have it collect on your kitchen countertop).

In any case, the reason why we’re pointing out these steps now is that the majority of them involve the use of certain markers and guides that will aid the user during assembly. Without these markers and guides or with poorly implemented markers and guides, assembly is much more difficult than it is with markers and guides that are easy to see, easy to follow, and properly labeled. Some models in this category (vertical masticating) implement them well while others do not. Let’s see how the B6000S (and C7000S) does as we take a look at each step required for assembly more closely.

Step 1

The first step of assembly involves fitting the juicing bowl to the main body of the juicer. Right away we have to add a very important note to this step which also applies to all of the steps that follow. What we just described is not the first step of assembly outlined in the B6000S’s user manual. The steps that follow will also not follow the same order as described in the manual. The reason why we outline the steps required for assembly differently here than they are outlined in the manual is because the steps we’ll be describing here follow what we actually did during our testing, not what should be hypothetically done according to the manual.

Here is a summary of how our assembly differs from what the manual instructs: The manual instructs the user to assemble all of the parts that go inside of the juicing bowl first – our steps 2 through 4 are the manual’s steps 1 through 3. And then as a final step, to fit this “top-set” to the main body of the juicer – our step 1 is the manual’s step 4; however, in our step 1 the juicing bowl is empty while in the manual’s step 4 the juicing bowl contains the auger, strainer, and spinning brush and the feeding chute assembly is already fitted to the top of the juicing bowl.

It’s important for us to make you well aware of this difference in assembly order now as it impacts step 1 more than any other step that follows. For our step 1 you are fitting the juicing bowl to the main body of the juicer without the feeding chute attached. The issue is that the feeding chute is labeled with a marker and guide (a white arrow) that matches a marker and guide on the main body (a close and open label that matches with the arrow on the feeding chute assembly). There is no marker on the juicing bowl that matches the marker on the main body. If carrying out the steps required for assembly in the same order outlined in the user manual, the feeding chute assembly is already attached the juicing bowl when it’s fitted to the main body and so you can use these markers and guides to attach the “top-set” (which includes the juicing bowl) to the main body. Doing things our way, the feeding chute assembly isn’t there to help align the juicing bowl to the main body and so you will have to rely on experience, common sense, or a bit of trial and error to get it to fit into the main body by itself and be firmly secured in place.

Reading through the above paragraph you may be thinking, “why are we making things more difficult for ourselves?” or “why don’t we just follow the user manual’s instructions for assembly and use the markers and guides in the way in which they were intended to be used?”. The answer to these questions lies in the fact that we found the rest of assembly, the next several steps, much easier to carry out doing things our way as compared to the manual’s way. Yes, this one step is slightly more difficult than it would be by doing things the standard way outlined in the manual. But the majority of assembly – most of the steps that follow – is made easier because we begin assembly in step 1 our way.

Things are made easier doing things our way because fitting and securing the juicing bowl in step 1 allows for a firm, stable foundation on which to build when carrying out the steps that follow. Assembling according to the steps outlined in the manual, you need to fit the strainer/spinning brush, auger, and feeding chute assembly to the juicing bowl while it is sitting loose on the countertop next to the main body of the juicer. This requires that you use one hand to hold the juicing bowl in place and use the other hand to place each part into and onto the juicing bowl. Doing things our way, you have the main body of the juicer replacing your one hand holding the juicing bowl in place. You can now use both hands to fit the strainer/spinning brush into the juicing bowl in step 3, to fit the auger into the juicing bowl in step 4, and the feeding chute assembly to the juicing bowl in step 5. Four steps are made much easier doing things our way at the cost of one step, this first step, being made more difficult.

Step 2

Step 2 involves fitting the strainer inside the spinning brush. The spinning brush is just the right diameter for you to be able to fit the strainer snugly inside of it. There is a little bit of adjustment needed to fit it just right but you should be able to complete this step in only a few seconds and without much difficulty.

Step 3

The third step of assembly requires that you take the strainer and spinning brush, which are now essentially one part, and place them inside of the juicing bowl. The bottom of the spinning brush has ridges that need to fit in between the teeth of the gear sitting horizontally on the bottom of the juicing bowl. If the ridges don’t fit in place the spinning brush and strainer will sit higher than they should within the juicing bowl and they will not lock into place. For the spinning brush and accompanying strainer to fit exactly in place as they should you will need to rotate them together until the red dot on the top edge of the strainer is aligned with a matching red dot on the top edge of the juicing bowl. These red dots stand out and are clearly visible looking down into the juicing bowl from overhead. With the two dots aligned the ridges on the bottom of the spinning brush should fall into place exactly between the aforementioned gear teeth and the both the strainer and spinning brush should lock into place.

Step 1 (left), 2 (middle), and 3 (right) of assembly.

Step 4

Next the auger needs to be placed inside the juicing bowl. It should be fitted to the top of the motor shaft extending through the center of and into the juicing bowl. The B6000S/C7000S’s auger is unique in that it’s very long. Most other vertical masticating juicers we tested have an auger between 4.25 and 4.5 inches in length. The B6000S/C7000S’s auger is 6.5 inches long. This is important because the Kuvings’ auger is so long that the top of the auger extends well above the height of the juicing bowl, strainer, and spinning brush when it’s properly seated on the motor shaft. The auger on most other juicers of the same type is short enough that it extends above the height of the juicing bowl only when it is not properly seated on the motor shaft. The user is able to confirm that the auger is properly seated when its height matches that of the top of the juicing bowl. This is, of course, not possible with the B6000S, making this step of assembly a bit more challenging than it is for most other vertical masticating juicers we tested.

Note how the B6000S/C7000S’s auger extends above the juicing bowl.

Step 5

The fifth step is to fit the feeding chute assembly to the top of the juicing bowl. There is a large red dot next to the label “OPEN” on the lid of the feeding chute assembly that should be aligned with the same red dot on the juicing bowl used to properly install the strainer/spinning brush in step 3. Simply turn the feeding chute assembly clockwise until the red dot on the juicing bowl aligns with the label “CLOSE” on the feeding chute assembly lid to secure it in place.

Step 6

As a final step, pull the juice container under the juice spout and the pulp container under the pulp outlet. Assembly is now complete and you’re ready to juice.

Assembly Summary

We began our discussion of the Kuvings whole slow juicer’s assembly by pointing out that what influences its assembly difficulty more than any other factor is how well the parts required for its assembly are labeled and marked to help with assembly. How then, does the B6000S (and C7000S) compare to its competition in terms of how well its parts are labeled?

The answer is, for the most part, very well. The strainer and juicing bowl are clearly marked with large red dots that makes proper alignment a breeze. The feeding chute assembly has the same size and color dot that can be aligned to the dot on the juicing bowl quite easily as well. The large white arrow on the back of the feeding chute assembly that is to be aligned with the same type arrow on the back of the main body of the juicer is large enough and marked clearly enough to minimize confusion when fitting the top-set (juicing bowl, strainer, spinning brush, auger) to the main body of the juicer. However, we do not recommend that the whole top-set be fitted to the main body in this way and so these labels were not as useful to us as they would be otherwise.

The bottom line is that the B6000S/C7000S’s parts are labeled just as well as most other vertical masticating juicers we tested. There’s nothing that stood out about the implemented markers and guides that compel us to give it above average marks in this category. On the other hand, the fact that the manual instructs users to assemble parts in a less efficient manner than what we believe is best, compels us to detract from the Kuvings’ score in this category. We therefore give it only a slightly above average 4 out of 5 for assembly difficulty.

Food Preparation

Its oversized 3-inch diameter feeding chute makes food preparation much less of a concern with the B6000S (and C7000S) than it is with most other masticating juicers on the market. Most other masticating juicers we tested have a feeding chute between 1.25 and 1.75 inches wide and between 1.5 and 2.5 inches long. Most vertical masticating juicers we tested have a slightly larger feeding chute than most horizontal masticating juicers we tested, but the B6000S/C7000S is in a class of its own with its self-proclaimed “wide mouth feeding chute”. The only other masticating juicer we tested that had a feeding chute similar in size to the B6000S’s (and C7000S’s) was the SKG wide chute juicer. It also has a 3-inch diameter feed chute.

Feed chute size is not, however, the only factor that determines just how much food preparation is required prior to juicing with any particular juicer. As we’ll see shortly, two other factors – juicer type and produce type – are just as important if not more important than feed chute size in determine how much you will need to cut any particular fruit or vegetable before juicing it.

Juicer type makes a difference as vertical masticating juicers process food much differently than horizontal masticating juicers, centrifugal juicers, and twin gear juicers. A centrifugal juicer with a 3 inch feeding chute may require much different food preparation than a vertical masticating juicer with a 3 inch feeding chute just because of the difference in the way that each type of juicer processes food to juice it. We’ll see this exemplified later on when we look at what type of preparation is required for juicing carrots with the B6000S/C7000S as compared to the preparation required for juicing carrots with a typical horizontal masticating juicer.

You may be asking how you’ll know – how we knew – how juicer type effects food preparation and what we needed to do to cut the produce we tested in a manner that would make each juicer we tested juice as efficiently as possible. For example, how did we know that we should cut carrots differently for horizontal masticating juicers compared to vertical masticating juicers or centrifugal juicers? Two things contributed to our understanding of how juicer type effects food preparation. First, we referenced the manual for each juicer we tested. Manuals for masticating juicers explain how to cut certain produce much differently than manuals for centrifugal juicers as manufacturers of such juicers are well aware of the limitations of this type of juicer and how those limitations dictate how much food preparation is required. Second, we were able to use our experience in testing different types of juicers in the past. We would experiment with different cutting techniques prior to our final tests. This is how we knew that we didn’t need to cut carrots at all for the vertical masticating juicers we tested, when the manuals for those juicers would often indicate that they should.

Finally, produce type also makes a difference in proper food preparation. Soft citrus fruits such as oranges can be cut slightly larger than hard apples and fit into the same sized feeding chute just as well. Carrots and celery stalks are both longer than they are wide, often a similar length and a similar width and so it would logically follow that they should be prepared similarly to fit into the same size feeding chute. What we found, however, is that celery stalks require that extra precautions be taken when juicing them that are not required when juicing carrots.

With all of these factors in mind, let’s take a look at how each of them made a difference in how we prepared produce for juicing with the B6000S (and C7000S), specifically.

A Word of Caution About Our Test Data

For each of our juicing performance tests we juiced exactly 1 lb. of produce. For our orange juicing performance test we juiced 1 lb. of oranges, for our spinach juicing performance test we juiced 1 lb. of spinach, etc. What that 1 lb. of each particular type of produce would be composed – how many items it would be composed of – would vary when testing one juicer compared to another. For example, the 1 lb. of celery juiced with the Champion juicer was composed of 23 celery stalks. The 1 lb. of celery juiced with the Hurom HU-100 was composed of only 14 celery stalks. Both juicers required that celery be cut to small 2 inch pieces but because the celery used for juicing with the Champion was composed of so many more celery stalks it took much longer to cut those stalks than it did when cutting stalks to juice with the HU-100. For this reason, we will only use average times to describe food preparation time moving forward in this review. Instead of saying that it took us 113 seconds to cut 1 lb. of celery for the Champion and only 48 seconds to cut the same amount (1 lb.) of celery for the HU-100 we will say that both juicers required that celery be cut to 2 inch pieces and that cutting 1 lb. of celery into 2 inch pieces took us an average time of 66 seconds to do based on data acquired from having to cut 1 lb. of celery to the same size for 10 different juicers that we tested. We will apply this same principal when assessing how much time was required for preparing produce for juicing with the B6000S (and C7000S).

Food Preparation Comparison to Other Tested Juicers

As we discuss how much cutting was required for each specific fruit and vegetable listed below we will not only note what was required for the B6000S (and C7000S), specifically, but also compare it to what was required for the same fruit or vegetable for other juicer types and specific models. We will also begin our discussion of each fruit or vegetable’s preparation by noting what the B6000S’s manual instructed us to do and whether we followed the manual’s instructions or not.

Oranges

The B6000S’s manual is very detailed in its description of how each type of fruit or vegetable needs to be prepared prior to juicing. It organizes its instructions into four different sections for four different types of fruits or vegetables: (1) soft fruits and vegetables (2) hard fruits and vegetables (3) ingredients with small seeds and (4) fibrous and/or tough leafy ingredients. Each section lists bulleted instructions under two different headings: (1) preparation tips and (2) extraction tips. Relative to the current discussion we will only discuss what the manual outlines under preparation tips.

Oranges fall into the category of soft fruits and vegetables. The B6000S’s manual instructs that this type of produce should be cut into one to four wedges. Since it doesn’t really make sense to cut anything into one wedge we can only assume that the intention is to say two to four wedges. In any case, the manual’s instructions here didn’t even apply to our testing. The oranges we used for juicing were small enough to fit into the B6000S’s feeding chute whole and so we did not cut them at all prior to juicing. The SKG wide chute juicer was the only other slow juicer we tested whose feeding chute was able to accept oranges whole.

In order to juice oranges with every other slow juicer we tested we needed to cut oranges into quarters at a minimum. This was the case for most vertical masticating juicers we tested. Three of the five horizontal masticating juicers we tested and the one twin gear juicer we tested, the Green Star Elite, required that the oranges be cut even further, into eighths.

The B6000S (and C7000S) being able to juice oranges whole makes for quite a time savings in terms of the overall time that it will take you to juice oranges with this juicer. When juicing 1 lb. of oranges with juicers that require that you cut them first, add 24 seconds of prep time for juicers that require them to be cut to quarters and 54 seconds for juicers that require them to be cut to eighths. These times represent the average time it took us to cut oranges into quarters and eighths, respectively.

Grapes

Grapes fall into the category of “ingredients with small seeds” described in the B6000S’s manual. The manual, in this section, doesn’t say anything about cutting such ingredients. It only warns that frozen ingredients of this type should be thawed, that grapes should be washed and removed from the stem, and that pomegranate skin should be removed prior to juicing. Of course, the manual didn’t exactly need to tell us anything about cutting such ingredients as common sense was enough to tell us that we could juice grapes whole with the B6000S, just as we did for every other juicer we tested.

Carrots

Carrots fall into the category of “hard fruits and vegetables” as described in the juicer’s manual. And, sure enough, next to the heading for this section is a friendly cartoon carrot next to a diagram showing you exactly how to cut carrots for juicing with the B6000S. The manual instructs that carrots should be cut 1 inch thick (or 1 inch wide) and 2 to 6 inches long. Based on our experience with juicing with other vertical masticating juicers and based on the fact that most of the carrots we were juicing weren’t much thicker than 1 inch or longer than 6 inches we decided to not cut carrots for juicing with the B6000S.

We did the same for every other vertical masticating juicer we tested – we did not cut carrots for juicing with them. We briefly experimented with cutting carrots into smaller pieces for juicing with this type of juicer (with the Breville Juice Fountain Crush) and our tests conclusively showed that carrot length didn’t make any difference in juice yield.

We also didn’t find it necessary to cut carrots for most of the centrifugal juicers we tested. The only juicers that would have given us some trouble juicing carrots whole – the only juicers that required that we cut carrots into smaller pieces – were the horizontal masticating juicer we tested. For reasons we outline in their respective reviews we had to cut carrots into small 2 inch pieces when juicing them with all of the horizontal masticating juicers we tested. Add 50 seconds to preparation time should you want to juice 1 lb. of carrots with a horizontal masticating juicer. 50 seconds that you save in preparation time when juicing carrots with a vertical masticating or centrifugal juicer.

Celery

The B6000S’s manual specifically addresses celery under the section entitled “Fibrous and/or tough leafy greens”. The manual warns that “the tough fibers from tough ingredients like celery can wrap around the juicing screw (auger) and affect the juicer’s performance”. We certainly heeded this warning not only with the B6000S but also with every other masticating juicer we tested.

The manual instructs that such ingredients should be cut to 4 inches. We cut the celery we prepared for the B6000S to much smaller 1 inch pieces. We did the same for the Breville Juice Fountain Crush and SKG wide chute juicer. For the other slow juicers we tested we cut celery into 2 inch pieces. There was no reasoning behind cutting celery to 1 inch pieces or 2 inch pieces, specifically. Instead, the aim was to cut celery simply into small pieces each time we were preparing it for juicing with each slow juicer we tested. By chance we cut the celery we prepared into smaller pieces for the B6000S and two other juicers (the Breville and SKG) than for the rest of the slow juicers we tested.

In any case, cutting 1 lb. of celery to 1 inch pieces took us an average of 121 seconds and cutting the same quantity of celery into 2 inch pieces took us an average of 66 seconds. You can certainly get away with cutting celery to as large as 2 inch pieces and you are likely to be fine cutting celery as large as 4 inch pieces when preparing it for juicing with the B6000S. We therefore conclude that preparing 1 lb. of celery for juicing with the B6000S should take a maximum of 66 seconds (should you cut it to 2 inch pieces) but is more likely to take well under a minute – probably around 30 seconds (should you cut it to 4 inch pieces). Note that no preparation time is required for juicing celery with a typical centrifugal juicer as there is no concern for celery wrapping around the auger of such a juicer (they don’t even use an auger for juicing).

Apples

We consider apples to be hard fruits; however, the B6000S’s manual clearly shows an apple cartoon underneath the “soft fruits and vegetables” heading. It also shows an apple being cut into smaller wedges in the same section. Regardless, the instructions outlined underneath this section certainly apply to apples just as well. Those instructions read “cut 1-4 wedges”. Unlike the oranges we juiced, the apples we juiced were large enough to warrant our actually following the manual’s instructions and cutting the apples into 4 wedges. The same was required for all of the 3 inch diameter feeding chute centrifugal juicers we tested. Most of the slow juicers we tested required that apples be cut even more than oranges. Most other vertical masticating juicers we tested required that apples be cut to eighths while some horizontal masticating juicers required that we cut apples into 16 or even 32 smaller wedges.

Obviously the smaller the pieces need to be cut to the more time is required for cutting. It took us only 18 seconds on average to cut apples to quarters, as we did for the B6000S. It took us 46 seconds on average to cut them into 8 wedges and 99 seconds on average to cut them into 16 wedges. Depending on which specific juicer you’re comparing the B6000S to, you’ll gain either no time (when comparing it to centrifugal juicers), approximately 30 seconds (when comparing it to juicers that require apples to be cut to eighths), or approximately 1 minute (when comparing it to juicers that require apples to be cut to sixteenths) when preparing 1 lb. of apples for juicing.

Spinach and Wheatgrass

The B6000S’s manual advises that leafy ingredients such as celery (with its leaves intact) and kale should be cut into smaller lengths before juicing. Because we used baby spinach for our testing which inherently is composed of small leaves we did not need to cut it prior to juicing it. We did not cut spinach for any of the other juicers we tested as well.

The manual doesn’t specifically point out that wheatgrass falls into the “fibrous and/or tough leafy ingredients” category but it can be inferred that this is the case from the fact that it does address how to properly insert wheatgrass into the feeding chute for maximum extraction in the same section. Regardless, the wheatgrass we used for juicing was already pre-cut to a length less than 4 inches and so we did not need to do anything with regards to cutting it in response to the manual’s directions to cut it to such a length in the same section.

Other Notes

Before we wrap up this part of the review and summarize food preparation for the B6000S/C7000S below, we want to address certain extra instructions outlined in its manual that we didn’t discuss above. These extra instructions are important because if they are not followed properly and the juicer is damaged the warranty for the B6000S may be voided. The manual clearly states that “juicer damage due to owner negligence or from not following the instructions in the owner’s manual will void the warranty service.” Let’s take a look at what these extra instructions are, how they relate to what we did for our testing, and whether it’s absolutely necessary for you to follow them to prevent voiding the juicer’s warranty.

1. Remove hard seeds and hard or inedible skins

The manual advises that you remove hard seeds from fruits such as peaches, plums, mangos, etc. It also advises that your remove hard skins from pineapples, melons, etc. We definitely followed these directions during our testing and recommend that you do the same to prevent damage to the juicer.

2. Juice low water content produce in combination with high water content produce

The manual recommends that you should always try to juice low water content produce such as hard roots and leafy greens with high water content produce such as oranges or pears. Because we wanted to compare how well different juicers could juice individual fruits or vegetables we did not follow this recommendation during our testing. The carrots, celery, apples, and spinach we juiced were juiced without adding any high water content fruits or vegetables to the mix. It is our recommendation that you follow the manual’s advice and that you do try to juice a combination of fruits and vegetables when juicing at home. However, we do not believe that juicing individual low water content produce will necessarily do damage to your juicer. We tested over 30 juicers and not one of them was damaged during our testing.

3. Soak hard ingredients in cold water prior to juicing

Again, we did not follow this recommendation during our testing as it would have introduced unnecessary variance into our experiments. We certainly could have soaked the carrots we used for testing but if we did so we would have no way to determine the extent to which carrots were soaked for one test as compared to another. Carrots that absorbed a lot of water would have juiced to a much higher yield than carrots that had absorbed less water. To eliminate this variable we didn’t soak carrots at all. Should you soak hard produce such as carrots prior to juicing? You certainly can and it will make things easier on your juicer should you do so but we do not feel that it is absolutely necessary to do so in order for you to not damage the juicer.

4. Do not collect more than 500g of leafy green juice per session

500g is half a kilogram or 17.6 ounces. We never attempted to juice more than 1 lb. or 16 ounces of leafy greens at a time for any of our tests and so none of the juicers we tested yielded more than 16 ounces of juice during testing. The B6000S, specifically, yielded 7.6 ounces of juice from juicing 1 lb. of baby spinach. Thus, you would have to juice more than 2 lb. of leafy greens to reach the manufacturer limit of 500g of collected juice. 2 lb. of leafy greens and the approximately 15 ounces of juice the juicer will make from it is a generous amount and you’re highly unlikely to want to juice more than this amount of leafy greens at any one particular time. If you do want to juice more than 2 lb., we definitely recommend that you stick to the manufacturer’s recommendation: juice the 2 lb. but then clean the top-set of the juicer (the juicing bowl, strainer, etc.) first before continuing to juice more. Juicing leafy greens puts quite a bit of strain on the juicer. In addition, the pulp generated by juicing this type of produce can clog the juicing strainer over time. It is for these reasons that the manual makes these recommendations and that we recommend that you follow them to prevent damaging the juicer and voiding the warranty.

Food Preparation Summary

We began our discussion of preparing produce for juicing with the B6000S (and C7000S) by pointing out the fact that its large 3 inch diameter feed chute puts it in prime position to be a juicer that requires less food preparation than most others. What our testing showed was that while this was certainly the case for juicing soft produce such as oranges and even certain harder types of produce such as apples, it certainly was not the case for juicing carrots and celery.

The B6000S was one of only two masticating juicers we tested that could juice oranges whole and for which we had to cut apples only into quarters. Every other slow juicer we tested required that oranges be cut to at least quarters and that apples be cut into at least 8 different pieces. Here the B6000S has a large advantage, at least in terms of food preparation, over almost every other masticating juicer we tested.

When it came to juicing certain hard produce, however, we found that the B6000S’s 3 inch feed chute did little to enable it to accept larger pieces of fruits or vegetables than comparable juicers with smaller sized feed chutes. Carrots are inherently long and thin so we could feed them just as well into the other vertical masticating juicers we tested as we could feed them into the B6000S. Yes, it is possible to feed more than one carrot at a time into the feed chute of the B6000S – something that isn’t possible with a juicer with a smaller feed chute. However, the owner’s manual strongly advises against doing so and for this and other reasons which we won’t discuss here we didn’t do so during testing.

Carrots were not the only hard vegetable that required just as much preparation for juicing with the B6000S as many of the other slow juicers we tested. We had to cut celery just as small for the B6000S as we had to for all other masticating juicers we tested. This is because the B6000S even with its oversized feed chute is still a masticating juicer and as such it has certain limitations inherent to masticating juicers. To prevent the juicer’s auger from jamming during juicing we had to cut celery for the B6000S despite its large feeding chute.

That all being said, these tables found in our general buyer’s guide summarize our findings and neatly compare food preparation requirements for the B6000S (and C7000S) to that of other juicers we tested.

Performance

To test the Kuvings whole slow juicer’s performance we used it to juice 7 different fruits and vegetables in 8 different tests. For the first 6 tests we juiced 1 lb. of each fruit or vegetable that was to be tested. For our orange juicing test, for example, we juiced exactly 1 lb. of oranges. For the 7^th test we juiced only 4 oz. of wheatgrass. Finally, we juiced 2 lb. of produce for our combination test in which we juiced 1 lb. of oranges and 4 oz. each of spinach, carrots, celery, and apples in combination. This test was unique in that we tested more than one type of produce at the same time by alternating feeding different fruits and vegetables into the juicer.

A Few Words About Our Testing Methodology

We already touched on one of the many goals of our testing when we mentioned how we tested a certain amount of wheatgrass to simulate real world application of the juicer. For much more on our testing methodology including the reasons why we selected certain types of produce for juicing, why we chose to juice in the particular way in which we did, and why we chose to measure the yields that we did, please see here.

Out of Juicer Yield vs After Sieve Yield vs % Yield

During juicer performance testing we recorded two types of measured yield in addition to a type of calculated yield. The first type of measured yield is what we call “out of juicer” yield. This is simply the raw yield as it came directly out of the juicer. The second type of measured yield is what we refer to as “after sieve” yield. This is the yield that was measured after we poured the initial out of juicer yield through a sieve. Finally, the only type of calculated yield that we use for analysis and comparison is % yield. Percent yield is calculated by taking either the out of juicer or after sieve yield, dividing it by the initial dry weight of the produce, and then multiplying that number by 100%. For example, if we juiced 1 lb. (16 oz.) of oranges and the juicer extracted 8 oz. of juice we would divide 8 by 16 which equals 0.5 and multiply it by 100% which equals 50%. In this example the out of juicer percent yield for oranges is 50%.

Juicing Performance Results

This part of our general buyer’s guide shows tabled test results for the B6000S (and C7000S) side by side with the those of all other juicers we tested.

Juicing Performance Summary and Score

As the table we referenced above shows, the B6000S’s test results were far from impressive. It garnered below average results in the majority of tests. Its best performance was in our apple juicing test and even there it managed to yield a volume of juice that wasn’t much better than what most of the 13 other slow juicers we tested were able to yield in the same test. Here are its after sieve yield placements for all 8 tests in order: 10^th, 13^th, 10^th, 12^th, 6^th (the lone bright spot that we just mentioned), 9^th (barely an average result in our spinach test),  8^th (a decent result in our wheatgrass test), and 13^th (this was its result for the combination test for which we only measured out of juicer yield).

What are we to make of these test results? Do they make the B6000S (and C7000S) a juicer that you should avoid buying at all costs? To answer these questions, we need to put the Kuvings’ test results within a certain context. That context is that the B6000S (and C7000S) is a whole slow juicer. It is designed for those consumers looking for the quality of juice that can be extracted from a masticating juicer without having to sacrifice the time it takes to normally prepare produce for such a juicer and actually go through the process of juicing with such a juicer. When testing all juicers we also recorded the time it took us to juice each of the fruits and vegetables that we juiced. The B6000S ranks in the top 2 in each and every category except for juicing wheatgrass where it ranks 4^th. It took us only 44 seconds to juice 1 lb. of oranges with the B6000S. Juicing the same quantity of produce with all of the slow juicers that we tested took an average of more than a minute longer – 1 minute, 45 seconds. It took us a mere 46 seconds to juice 1 lb. of apples with the B6000S. The same task took an average of almost 3 minutes for all of the slow juicers we tested. The pattern at this point should be clear – it takes much less time to juice the same quantity of produce with the B6000S (and C7000S) than it does for most other slow juicers that we tested.

We’ve already discussed food preparation for the B6000S at length earlier in this review but remember, preparing all of the fruits and vegetables we used for testing took us about 3 minutes to do for most other slow juicers we tested. Doing the same took us only about a minute and half to do for the B6000S. This is yet another category in which the B6000S excels in compared to the competition.

The bottom line is that the B6000S (and C7000S) is not a juicer we recommend if maximum yield is your highest priority. The juicer’s most unique feature is its extra wide mouth feeding chute. This design feature provides several benefits including lesser requirements for food preparation and lower juicing time. Unfortunately, these benefits do come at a cost – and that cost is lower yields. So, if your goal is to buy a juicer that will provide you with maximum yields our suggestion is to look elsewhere. If, however, you’re willing to sacrifice a few ounces of yield for the sake of being able to juice almost as fast as you can juice with a centrifugal juicer but with the benefit of making juice that tastes just as good as the juice extracted from a slow juicer, either the B6000S or C7000S may be the juicer for you.

Cleaning

The juicer’s included manual is very detailed in its description of how to go about disassembling and cleaning the juicer after use. It provides several tips to make cleaning the juicer easier, the most important of which is what the manual refers to as “quick rinsing” the juicer or what we simply call “pre-washing” the juicer. To pre-wash you simply run water through the juicer the same way you run fruits and vegetables through it when juicing (with the juicer turned on). It is recommended that you close the juice cap to allow water to well up in the juicing bowl when doing so. The accumulated water will be pushed around the juicing bowl in the same way juice is when juicing. This will allow the water to rinse a maximum area within the juicing bowl.

As the juicer’s manual does, we recommend pre-washing the juicer after each use. If you plan on using the juicer later in the same day you can get away with only pre-washing it before using it again later on. If it’s your final or only time using the juicer for the day we still recommend pre-washing before washing all parts in earnest in the sink.

During testing we pre-washed and washed all parts in the sink after each test to ensure that no leftover pulp or juice would be introduced in measured yields. For our final test (our combination test) we actually filmed and recorded the time it took us to clean all of the juicer’s parts in the sink. We did the same for all of the other slow juicers we tested as well. For the vertical masticating juicers (the B6000S/C7000S falls in this category) we tested, the average time it took us to clean all parts in the sink was 5 minutes. For horizontal masticating juicers the same task took us 4 minutes on average and for centrifugal juicers the same task took us about 6 minutes on average. Thus, the time that it takes to clean a vertical masticating juicer’s parts in the sink is an average time (5 minutes is right in between 4 and 6 minutes) compared to the same time for other juicer types.

Cleaning Method

We’ve already discussed the procedure that should be followed for pre-washing the juicer before it’s fully disassembled and its parts are washed in the sink. Once it’s disassembled, washing its parts in the sink involved 3 steps. First, we made sure to fill the sink about halfway with warm soapy water. Second, we placed the parts in the sink to soak. Those parts that required the least amount of soaking (juice and pulp containers, food pusher) were washed first. Third, we washed most of these parts with a microfiber cloth. The fourth and final step was to place the parts under running water under the faucet to rinse. We then placed them on a dry towel on the countertop next to the sink to dry.

Some parts required a few extra steps. Those parts in which pulp had accumulated required that we remove the pulp from them before washing them. We removed pulp from the pulp container by hand and pulp from the juicing bowl’s pulp outlet using both of the two included cleaning brushes (the handle of one brush and the actual brush of the other). We used both one of the cleaning brushes and the included strainer cleaning tool to clean the strainer although using just one of these two cleaning tools would have been sufficient.

Cleaning Tools

The B6000S (and C7000S) comes with two different cleaning brushes and a cleaning tool for the strainer. The inclusion of two cleaning “tools” is well above and beyond the one standard cleaning brush included with most other slow juicers we tested. Which tools you use to clean particular parts is a matter of personal preference. We chose to use all three cleaning tools during testing in order to get a feel for what we liked the most. That being said, we definitely preferred using the heavier duty of the two included cleaning brushes to clean the strainer than the bonus cleaning tool included with the juicer to be used specifically for that purpose. The strainer cleaning tool can only clean the outside of the strainer and we found it necessary to clean the inside of the strainer as well. To do so we had to use a brush.

As we mentioned earlier we used both the handle of the heavier duty brush and the actual brush end of the less heavy duty brush to clean the juicing bowl and while you could probably get away with using only the heavier duty brush, being able to use the less heavy duty brush in conjunction is a nice bonus and definitely makes the cleaning process a bit easier.

Pulp Accumulation

After pre-washing each vertical masticating juicer we tested we noticed that each juicer had different amounts of pulp that had remained accumulated within certain parts. Those parts were the bottom of the auger, the strainer, and the juicing bowl. We didn’t observe any excessive pulp accumulation within the bottom of the B6000S’s auger but definitely noticed extra accumulation in its strainer and juicing bowl. This extra accumulation of pulp required that we remove it with the handle of the heavier duty cleaning brush while placing these parts under running water.

Staining and Deposits

In order to make the parts that compose their juicers more stain resistant most slow juicer manufacturers make those parts using stain resistant materials. Normally, the only characteristic of those materials that makes them more stain resistant is their color. Dark plastics are much less likely to stain than light plastics. Orange and green parts are much less likely to stain than any other colored parts (orange and green produce such as carrots or spinach stain most easily and so staining is less pronounced on similarly colored parts).

Kuvings has done an excellent job making all of the B6000S’s (and C7000S’s) parts stain resistant by selecting only dark and orange plastics to construct most of its parts. The juicer’s feeding chute assembly, auger, and spinning brush are all made of black plastic. Its juicing bowl is made of a darkened clear plastic and its strainer is made of an orange plastic. The only parts that make up the juicer that are susceptible to staining are the (white plastic) gear inside of the juicing bowl and the clear juice and pulp containers although we did not observe any staining of these parts during testing.

Dishwasher Safe Parts

The fourth page of the juicer’s manual lists several safety warnings, one of which is “Do not put the juicer parts in the dishwasher or extremely hot water”. Note that most slow juicers we tested also cannot be washed in the dishwasher while most centrifugal juicers can (excluding the main body of the juicer of course).

Cleaning Summary and Overall Score

The B6000S/C7000S earns strong marks in this category for two reasons. First, Kuvings provides three different cleaning tools with your juicer purchase. While not all of these tools are absolutely necessary for cleaning they definitely can make the process much easier. Second, most of the juicer’s parts are highly stain resistant. As such, you don’t have to worry about repeatedly cleaning parts or soaking parts overnight to remove stains from them. Factoring in how the overall difficulty of cleaning a vertical masticating juicer such as the B6000S/C7000S compares to the difficulty of cleaning other types of juicers we give the Kuvings a solid 4.5 out of 5 for cleaning difficulty.

Ease of Use

Initial Learning Curve

The B6000S (and C7000S) is easier to learn how to use than most other slow juicers we tested. This is mostly because it has less stringent food preparation requirements than those other juicers (mostly due to its wide mouth feeding chute). Most other slow juicers, especially horizontal masticating juicers and twin gear juicers require that produce be cut in very specific ways to ensure that they can juice the same produce with maximum efficiency. Learning how to cut different types of produce correctly for these juicers takes a lot of time and experience. The B6000S/C7000S also has a few food preparation requirements (we discussed those requirements that do exist earlier in our review) but overall you’ll need to learn much less about preparing produce for juicing with the Kuvings whole slow juicer (and whole slow juicer elite) than you need to for even most other vertical masticating juicers we tested (which are generally easier to prepare produce for than horizontal masticating or twin gear juicers).

Other than with regard to proper food preparation, the learning curve for the B6000S/C7000S is about the same as it is for other slow juicers. It also requires that you learn how to assemble it, feed produce into it, and clean it over time. Accomplishing these tasks will be slow going at first as you learn to do them correctly and as efficiently as possible. Only after a few days, weeks, or months of use (depending on how frequently you use it) will you be able to put the juicer together, juice with it, and clean it properly and as quickly and efficiently as possible.

Continued Difficulty

Once you’ve gained some experience using the juicer the difficulty of assembly, disassembly, and use and care of the juicer will dwindle. However, certain difficulties that don’t become easier with experience will persist. Those difficulties are discussed below.

How Hard Is It to Push Produce into The Juicer?

Pushing produce into a masticating juicer can be difficult to do depending on juicer type. Horizontal masticating and twin gear juicers can require that a lot of force be exerted in order to push produce into their feeding chutes to allow them to actually process the produce and extract juice from it. Vertical masticating juicers do not. In fact, many of the vertical masticating juicers we tested didn’t require that we push certain types of produce down into their feeding chutes at all. When juicing grapes with the B6000S, for example, we didn’t even use the food pusher at all when juicing them. We simply dropped the grapes into the feeding chute and allowed gravity and the auger to pull the grapes into the juicing bowl to enable the juicer to process them and extract juice from them. To do the same with a twin gear juicer is simply impossible and being able to do so with a horizontal masticating juicer is highly unlikely.

Other Design Choices and Features that Improve or Detract from Ease of Use

Weight and Carrying Handle

No matter how many times you use the juicer it will always have the same weight and thus be either easy (if it’s light) or more difficult (if it’s heavy) to move around the kitchen to use it. Of course, should you keep it permanently on the countertop, you’ll only be moving its top assembly parts from the main body of the juicer to the sink (to clean them) – you won’t actually have to move the main body. If this describes how you’ll be using the juicer then its weight is not important. However, if you do plan on moving it around a lot, whether in and out of storage or simply from one location to another on the countertop, its weight can certainly make a difference as to how easy it is to use. The B6000S’s fully assembled weight and body only weight are listed in the table below along with the same measured values for comparable juicers. Note how juicers of the same type tend to weigh about the same and how the only three juicers that are distinctly less or more difficult to move around the kitchen compared to others are the Hamilton Beach 67950A, Tribest Green Star Elite, and Champion juicers.

Buttons and Controls

The B6000S (and C7000S) is controlled with a single switch on the front of the main body. The switch is clearly labeled “FORWARD”, “OFF”, and “REVERSE” and as such you won’t have any difficulty remembering which direction to flip the switch for either function.

 Juicer Movement, Power Cord Length

The Kuvings whole slow juicer has 4 rubber feet that keep it firm and secure on the countertop. We didn’t observe the juicer moving at all during testing (this phenomenon – the juicer moving around on the countertop while it’s juicing – was actually common with the centrifugal juicers we tested).

The B6000S/C7000S has a very long 59 inch power cord. Its long power cord will allow you to likely be able to place it anywhere on the countertop you’d like. A shorter power cord would limit you to being able to only place it close to wall outlets.

Other Factors That Affect Ease of Use

Manual Quality

The B6000S’s manual is the best juicer manual we’ve had the chance to have a look at thus far, and at the time of this review, we’ve taken a look at over 30 juicer manuals in preparation for the 31 juicers we tested for review. The B6000S’s manual is highly detailed with clear and cogent text accompanying high quality clearly marked diagrams which describe every aspect of juicer use and care you could possibly think of. The manual does an especially good job of describing proper preparation of produce for juicing – something that most manuals only briefly mention if they even discuss it all. It also gets into the intricacies of properly cleaning the juicer – another topic that most other manuals neglect to cover in detail. The comprehensive nature of the B6000S’s included manual makes the juicer both much easier to learn how to use and much easier to actually use over time.

In addition to a manual a 100+ page recipe book was also included with our purchase. The recipe book mirrors the quality of the manual as it is both highly detailed and comprehensive in its coverage. It describes in detail the steps necessary to make a wide variety different of juices, baby food, fruit cocktails, smoothies, and frozen desserts with the juicer.

Parts and Their Properties

The parts we listed for the B6000S (and C7000S) at the beginning of this review are the same parts you’ll find composing all other vertical masticating juicers we tested, with one exception – the juice cap. Some of the vertical masticating juicers we tested did not include this part. This is an important distinction to make because the juice cap is a very significant part in terms of improving your quality of life when using this type of juicer. And while it being included is a big positive, its absence is just as big of a negative. The juice cap can be used for

1. Making pre-washing the juicer a more efficient process.

We recommend that you always pre-wash any vertical masticating juicer before washing all of its parts in earnest in the sink. To pre-wash, operate the juicer in exactly the same manner as you would operate it when juicing, but instead of feeding fruits and vegetables into the feed chute, pour water into it. The water will take the same path through the juicer as a processed fruit or vegetable normally would, and during its journey, will rinse all of the parts it comes into contact with. Closing off the juice cap allows water to accumulate within the juicing bowl while the juicer is running which allows for the rinsing process to be carried out much more efficiently – not only will the water come into contact with a greater surface area of parts within the juicing bowl, but it will be able to soak those same parts at the same time.

2. Making pre-mixing juices a more efficient process.

When juicing a wide variety of different fruits and vegetables at the same time, the processed juice that accumulates within the juice container is normally a heterogeneous mixture which, quite simply, doesn’t taste very good should you pour it directly into a glass to drink it. To make the juice more palatable, you’ll normally want to mix it by hand using a spoon until it becomes more homogenous, blending the different types of juices together, and making the juice much more pleasant to taste. An even simpler and much more efficient way to go about mixing the juice is to simply close off the juice cap while you’re juicing. Doing so will enable the spinning brush rotating in the juicing bowl to mix the juice for you. Simply open the cap to allow the pre-mixed juice to accumulate in the juice container – you now have a juice that’s ready to pour into a glass for your enjoyment.

3. Further making juicing a variety of fruits and vegetables a more efficient process.

Speaking of juicing a wide variety of fruits and vegetables, should you do so it’s likely that you’ll juice a large enough quantity of produce to make so much juice that it exceeds the included juice container’s capacity. Should this happen, you’ll need to empty the container at some point while you’re juicing. Being able to close off the juice spout with a juice cap makes this a much more efficient process. When the juice container reaches capacity simply close the juice cap before you empty the container and place it back underneath the juice spout. Closing off the juice spout with the juice cap allows you to carry out the task of emptying and replacing the juice container while the juicer continues to run and you don’t have to make a mess of things while doing so.

Now imagine carrying out the same task using a juicer that doesn’t come equipped with a juice cap. Not only will you have to turn off the juicer before emptying and replacing the juice container, but you’ll have to be very careful to make sure not to have any juice leak out of the juice outlet and onto your countertop while you’re doing so.

Juice and Pulp Containers

In addition to the juicer’s juice cap two other included parts also have an impact on how easy (or difficult) the juicer is to use. Those parts are the juice container and the pulp container. The volume of these parts have a direct impact on the overall ease of using the juicer as explained here. The table below shows the size (in ounces) of the B6000S’s included juice and pulp containers compared to the size of the same containers included with comparable juicers.

	Juice Container	Pulp Container
Kuvings B6000S	42	48
Omega VSJ843QS	38	58
Tribest Slowstar	36	36
Omega 8004/8006	32	40
Tribest Solostar 4	32	32

Ease of Use Summary and Score

The B6000S/C7000S earns well above average marks or ease of use. It is easier to prepare produce for than other vertical masticating juicers when vertical masticating juicers, in general, are already easier to prepare produce for than other types of slow juicers. Its exceptional manual, its juice cap and its extra-large juice and pulp containers are also positives for it in the category. We give the Kuvings a perfect 5 out of 5 for ease of use.

Versatility

The B6000S/C7000S is more versatile than most other vertical masticating juicers (it includes a blank strainer and a smoothie strainer can be purchased separately) but not quite as versatile as other horizontal masticating juicers and twin gear juicers (most of these types of juicers include nozzles to extrude food in different ways in addition to a blank strainer). For more information on the versatility of this machine see our comments regarding its assembly for its many uses at the beginning of this review.

Durability

Build Quality and Materials

Both the B6000S and C7000S are very well made using very high quality parts. Most parts are constructed using highly durable thick and resilient plastics. The juicing strainer also incorporates the use of stainless steel.

Consumer Feedback

Consumer reviews for the B6000S are mostly positive though the juicer certainly does have its fair share of critics. There are several reports of the juicer malfunctioning or simply not working after just a few weeks of use. That being said, for every negative review there are at least 10 times as many positive reviews praising the juicer’s durability that contradict these negative reports. Consumer reviews for the C7000S are yet to be plentiful enough for us to comment on them.

Brand Reputation and Quality of Support

Kuvings is one of several slow juicer manufacturers, including Omega, Tribest, and Hurom that have factories in South Korea but market and sell their juicers worldwide. The only difference between Kuvings and Hurom vs Tribest and Omega is that Kuvings and Hurom are headquartered in Korea while Tribest and Omega are headquartered in the United States. Again, all four companies manufacture juicers in South Korea.

Despite being headquartered in Korea, Kuvings does have offices in the United States. As such, all US customer service and warranty claims are handled through their offices in the US, not through their main headquarters in Korea. Their US offices can be contacted via email, a 1800 number, a snail mail address, or via a contact form on their website at shopkuvings.com. Most consumer reviews we surveyed that comment on Kuvings customer service do so in a positive way. There are, however, several reports of Kuvings customer service not being very professional.

Warranty

The B6000S (and C7000S) comes with a rock solid 10-year warranty that covers all of the juicer’s parts. In our opinion, Kuvings juicers have some of the best warranties of all of the juicer warranties we surveyed for our reviews. Here’s why. First, warranty terms and exclusions are clearly listed on the Kuvings website. Warranty terms are often difficult to find listed explicitly anywhere for juicers manufactured by other slow juicer brands. Second, you can actually fill out an online warranty request form electronically on the Kuvings website. Most other slow juicer manufacturers require that you mail them a filled out hard copy warranty card and make warranty claims via phone. Third, Kuvings actually covers shipping costs if warranty claims are made within the first year of purchase. Most other manufacturers do not cover shipping costs under any circumstances. Fourth, product registration is encouraged but not required for warranty coverage. Certain other manufacturers, namely Tribest, actually require that you register their products within a certain number of days of purchase in order to receive warranty coverage for them.

Summary and Score

In our time using the B6000S and testing it for review there was nothing that we observed about the juicer or any of its parts that would give us the inclination to think that it is less well made or made using lower quality parts than any of the other similarly priced vertical masticating juicers we tested. And while the B6000S doesn’t include the 15-year warranty included with some Omega juicers, the 10-year warranty that is included with your purchase of this juicer is very well and clearly defined and very simple and easy to claim. We give the B6000S (and C7000S) a perfect 5 out of 5 for durability.

Value

Bonus Accessories

Our purchase of the B6000S included a wealth of different bonus accessories including three different cleaning tools (two more than what you get with most other slow juicers), a blank strainer (most other juicers of this type do not come with any additional strainers), and a 100+ page recipe book (again, something not included with most other juicers we tested).

Initial Cost

The B6000S’s price normally falls around the $400 mark, which makes it slightly more expensive than the Tribest Slowstar (normally priced around $380) and slightly less expensive than the Omega VSJ843 (normally priced around $430). At $400 it is a full $100 more than the vertical masticating Breville BJS600XL and most top rated horizontal masticating juicers such as the Omega NC800 and J8006 which normally retail for about $300. At $400 it is still at least about $100 less than the top rated twin gear juicer we tested, the Green Star Elite.

Long Term Cost

$400 is quite a bit of money to spend on a juicer. However, this amount is actually quite insignificant if you compare it to the total amount of money you’ll spend on produce (for juicing) during the life of the juicer. The cost of produce varies according to many factors, most of which you cannot control. However, a factor you can control is the juicer that you use to juice it. How well the juicer you end up buying juices produce has a tremendous impact on the money you’ll end up spending on produce during the life of the juicer. We discuss this phenomenon in great detail here.

Value Summary

The B6000S/C7000S’s lackluster performance in our juicing performance tests (with regards to yield) means that you will have to buy more produce to make the same amount of juice with the Kuvings, than you would have to with a high yield juicer such as the Green Star Elite (again, please read the write-up we linked to above to see why this is the case). In addition, its price is quite a bit higher compared to most other slow juicer options on the market. Its saving grace in this category are the myriad of bonus items that are included with your purchase. However, these items are not enough to sway us from giving the Kuvings whole slow juicer (and whole slow juicer elite) a below average 3 out of 5 for value.
