The Kuvings Whole Slow Juicer B6000S is a compression, or masticating juicer. Instead of a disk spinning at over 10,000 RPM like a centrifugal model, it has an auger that slowly rotates at 80 RPM, gently squeezing the juice out of your produce. While we can't substantiate the manufacturer's claim that this method doesn't break down nutritional compounds like a centrifugal model, we can tell you that this is a very good machine that produces a high quality glass of juice. It comes with a wide-mouth feed shoot, which does make it slightly easier to use than our Top Pick for Masticating Juicers, the Omega J8006, however you still need to cut up your produce fairly small otherwise it jams the machine and the juice ends up on the chunky side. The machine can also be used to makes smoothies and frozen sorbets, but at $430 it doesn't do anything appreciably better than the Omega J8006, which is "only" $300. If you are into top-of-the-line kitchen gadgets, then you won't be disappointed with this one, but if you are just looking for a juicer and nothing more, then our Editors' Choice award winner, the Breville Multi-Speed BJE510XL, is a cheaper and easier way to go.
Kuvings Whole Slow Juicer B6000S Review
Cons: Numerous moving parts, difficult to align, heavy
Our Analysis and Test Results
This machine weighs 14 lbs and has a smaller footprint than a standard piece of paper. It's a 240-watt machine and the auger spins at 80 RPM. It has a three-inch wide feed tube and a unique rotary cleaning brush, as well as a smaller brush for cleaning all the nooks and crannies. It also comes with a well-produced, full-color recipe book.
Ease of Use
The three-inch wide mouth on the Kuvings Whole Slow Juicer B6000S is supposed to cut down on prep time, however you still cannot place a whole carrot down the feed tube as this caused the machine to jam and the juice was very chunky. In fact, you have to slice carrots into fourths or even smaller if they are large, per the manufacturer's instructions. However, once the produce is in the chute, very little pressing is required, unlike the Omega J8006, as the vertical auger practically works itself.
As long as we chopped our veggies up a bit, this model produces a great quality juice with little pulp or sediment. However, it was heavy on the foam, particularly for greens. Although it extracted a high yield in our kale test, it had a thick one-inch foam residue on top. The juice from this machine wasn't as rich and creamy as the Breville models, which is likely due to the different extraction methods.
The Kuvings Whole Slow Juicer B6000S excelled at juicing greens and citrus, resulting in much higher yields than the centrifugal models. However, when it came to harder vegetables like carrots, the masticators yielded about 25 percent less.
Ease of Set-up & Clean-up
With various moving parts required for set-up, from the rotation wiper (a silicon-ribbed sleeve for the strainer) to the auger and compression silicon inserts for the pulp spout to prevent leakage, it's a bit confusing at first to get this product assembled. Additionally, the topset on the Kuvings Whole Slow Juicer B6000S is tricky to assemble and align. Even after multiple uses, we found ourselves struggling with the set-up, and repeatedly trying to set the auger down low enough for the lid to fit on top. Compared to a model like the Breville Compact BJE200XL, this machine is a lot harder to use.
From a cleaning perspective, this product is not that difficult to use. You can close the spout on the juicer, put a glass of water in the machine, turn it on, and it will do most of the cleaning for you. It also comes with a rotary cleaner, which you can place over the juicing strainer to de-gunk the fine mesh filter, but this didn't seem necessary most of the time. There was always pulp stuck in the pulp ejector spout and that was usually a bit of a chore to remove.
Ease of Storage
Despite its high price point and workhorse capability, this is a fairly compact machine with a small footprint. It is heavy though, and does not have a handle like the Omega J8006, so it's not that easy to lift and move. It is designed to fit into a cabinet, however, if your height clearance is limited, you may need to store it with the topset removed.
This machine comes with a blank "smoothie" screen. You can put whole fruits in there for blending instead of juicing, and even better, you can input frozen fruit to make delicious sorbets. However, it was a little messier to do this on the Kuvings machine compared to the Omega J8006. In the Omega, you can run the sorbet through a few times to get a uniform consistency and/or add yogurt or nut butters, but when we tried this in the Kuvings the sorbet just got stuck inside the mechanism and wouldn't come out. A messy battle with a spatula ensued. Unfortunately, the Omega VRT350 does not come with a blank screen, so you can only use that model for juicing.
We recommend the Kuvings Whole Slow Juicer B6000S for people who are into juicing greens and citrus, and also looking for a more versatile machine that can do other things like smoothies and sorbet. If you want to offer healthy desserts to your kids (or yourself!) this juicer is a good choice.
At $430, this machine is a big investment and we were hard pressed to find anything about it that was so much better than Omega J8006 as to warrant spending an extra $130. But if money is no object and you want a sleek machine for multiple uses, you definitely won't be disappointed with this one.
This is perhaps Rolls-Royce of juicers we tested; the smooth, quiet motor and lack of effort required to move produce through the feed tube make it almost hands-free. Combined with easy storage and the high quality juice, the Kuvings Whole Slow Juicer 6000S was a contender for our Top Pick award. However, the price point, heavy weight, and extra effort required for assembly and cleaning, are what put the Omega J8006 ahead of this model.
