The Omega VSJ843 is one of the slowest and quietest machines we’ve tested, and it produces juices without much foam. The VSJ843 produced almost as much green juice as our top pick, the high-yielding Tribest. So if you’re a devoted green juicer, you might prefer this Omega to our pick. However, for most people, its higher price, slightly lower yields on carrot-apple juice, and lack of versatility make it a second choice to our top pick.
A twin-gear juicer such as one of those in the Tribest Greenstar series can extract the most juice from greens like kale, spinach, and wheatgrass, but isn’t good at juicing fruit. The juicers in this series are specialty machines usually used in professional juice bars; they’re also quite expensive. We did not test any twin-gear juicers for this review.
An efficient design allows the Slowstar to crank out a high volume of juice within a small footprint of 6½ by 8 inches. The feed-tube opening is a relatively wide 2½ by 1½ inches—wider than the 1½-inch chute on the Omega J8004—which helps reduce the amount of vegetable prep you’ll have to do beforehand. The solid waste collects cleanly in a waste container that’s included. The Slowstar has a reverse button in the back in case you need to dislodge stuck vegetable matter, but I never needed to use it.
We got more juice out of the Kuvings Centrifugal Juicer NJ-9500UB than any other machine we tested. All that remained was a small amount of pulp that felt relatively dry to the touch. The Kuvings did an excellent job extracting juice from hard and soft produce in virtually all our tests. Since getting juice is the whole point of a juicer, the Kuvings got top marks.
And the Tribest Slowstar doesn’t just juice. It also comes with a “homogenizing” mincer attachment that grinds without extracting liquid—useful for making sorbets, nut butters, and more. I haven’t used the machine for anything other than making juice, so I can’t attest to its food-chopping and frozen-fruit-sorbet-making abilities, but you can see it in action in this DiscountJuicers.com video. The separate bowl attachment fits onto the base, using the auger to pulverize the food and push it through a large chute without a screen.
When your fruits or vegetables are put into a centrifugal juicer, they are grated into smaller slices and pieces through sharp teeth-like blades. These blades are usually found on the bottom of a basket-like part, such as the Nutridisk of the Breville 800JEXL, and less efficient than the augers found on masticating juicers. Juice is extracted during this process by through the pressure of centrifugal force as the ground-up parts of the fruits and vegetables are pressed against walls of a filter. The faster these juicers spin, the greater the amount of force applied during this process, and the great the amount of juice that is extracted. A typical Centrifugal juicer will have a motor with 800 watts of power or more spin at nearly 15,000 RPM and are regarded as being very noisy. The juices produced by these juicers have shorter shelf lives due to increased aeration associated with centrifugal separation processes.
To look for the best juicers to test, we read editorial reviews of juicers from Good Housekeeping, Real Simple, and Top Ten Reviews, and watched video reviews and comparisons of new models. We also looked at the offerings from the four main juicer companies at the forefront of juicing technology: Tribest, Kuvings, Omega, and Hurom. John Kohler said that these companies innovate and improve upon their technology, and the cheaper versions are often Chinese knockoffs. Watching hours of side-by-side comparison videos and reviews also helped narrow what to include from each brand.
"This is a gem of a juicer! I could not have purchased a better working, all inclusive machine. All the features I wanted without going overboard! Not knowing how much I would be using a juicer, I opted for a smaller price tag as they can run pretty crazy in my opinion. This one has a high & low optional switch which I mostly use the low juicing celery, cucumber, carrots, apples and some leafy greens. The wide mouth means I have to do very little cutting and prep, the juicer is thorough and i get very dry pulp leftover (which i've used in the puplp muffin recipe included in the manual). There is no extra assembly or dissasembly when I get it out of the cupboard it all pops together very quickly and comes apart easily for fast cleaning with the brush included. Overall I absolutely love it and definitely recommend it!"
