Juicer.Kitchen Verdict
One of the best vertical slow juicers currently available. The REVO830’s dual feed chute design genuinely changes the experience of daily juicing. The 3.5-inch wide chute accepts whole fruits and larger produce with little to no cutting, while the Auto-Cut chute slices long, fibrous ingredients like celery and carrots as they feed.
Most vertical juicers require celery to be chopped to prevent clogging. Horizontal juicers handle celery well but lack a wide feed chute. The REVO830 bridges that gap, combining the convenience of a wide chute with the fiber-handling ability of a horizontal design.
Yield is equally impressive. In our celery test, it produced the highest yield we’ve measured from any vertical juicer — matching the Sana 727, a horizontal model known for green juice performance.
Cleaning takes about 4–5 minutes, so it isn’t the quickest vertical to maintain. However, not having to pre-cut most produce helps balance that out. Built in South Korea and backed by a full 15-year warranty on all parts, the REVO830 is built for long-term use.
If you want a premium juicer that handles a wide variety of produce while minimizing prep, the REVO830 is an excellent choice.

Kuvings REVO830 Detailed Review
Intro
After more than a decade of reviewing juicers, we’ve cut more celery than we’d like to admit. Vertical juicers have always been our everyday choice because they handle almost everything equally well. Greens, fruits, roots — they do it all. But celery is the one ingredient that exposes the limitations of vertical designs. Anyone who has used a vertical juicer knows the routine: cut it small, feed it slowly, hope it doesn’t clog.
So the first time we dropped whole celery stalks into the REVO830 — no cutting, no fuss — and watched them disappear through the Auto-Cut chute without a single jam, we knew Kuvings had finally solved a problem the entire category has struggled with.
This is the first vertical juicer we’ve tested that can handle long, stringy ingredients like celery the way a horizontal juicer does, while still giving you the wide feed chute and versatility people expect from a vertical design.
Juicing Mechanism — Dual Feed Chute
The REVO830’s entire identity comes down to truly new and innovative dual feed chute:
- 3.5-inch Wide Chute (for larger produce)
Drop in whole apples, pears, peeled oranges, tomatoes — no slicing.
Kuvings invented and patented the first wide-chute slow juicer years ago, and this is their largest one yet.
- Auto-Cut Chute
A narrower chute built specifically for long, fibrous ingredients like celery, carrots, and rolled leafy greens. This chute feeds produce directly onto a newly designed auger with built-in cutting edges.
Why celery clogs vertical Juicers?
Most vertical juicers struggle with celery because of the way pulp exits the machine. As the auger squeezes the produce, the pulp has to make a sharp turn out of the pulp outlet. If celery isn’t cut into smaller pieces, the long fibers stay intact and can bunch up, wrap around the auger, or clog the outlet.
How Auto-Cut chute solves it?
The Auto-Cut chute solves this by feeding celery and carrots directly onto a redesigned auger with built-in cutting edges. As the auger rotates, it slices the produce into short, manageable pieces before juicing them. With the fibers already cut into small sections, the pulp moves through cleanly without forming long strings that cause jams.
Build Quality — Heavy, Solid, Built to Last
The REVO830 feels solid the moment you lift it. The 240-watt motor is one of the most powerful Kuvings has ever put in a household juicer, with more copper windings for extra torque — and it shows. In our testing, it snapped through wide carrots and fibrous greens with ease. It’s not a commercial unit, but it gets surprisingly close.
It’s rated for a 45-minute runtime. This means you can juice continuously for 45 minutes, then give it a short rest to cool down before running it again. For context, many popular vertical juicers — including the Nama J2 — are rated for around 30 minutes.
The parts feel just as robust. Everything is BPA-free, the auger and bowl are sturdy, and the containers are generously sized with a 1000 ml juice cup and a 1300 ml pulp bin.
On the counter, the REVO830 looks modern and well built — and more importantly, it feels like a machine designed to last for a long time.
How to prep the produce?
This is where REVO830 really separates itself from other slow juicers. This is the first vertical juicer we’ve tested that genuinely eliminates prep. Horizontal juicers usually require cutting most produce—except celery and leafy greens—to fit their narrow chutes, and vertical juicers almost always need celery chopped small to avoid clogs. The REVO830 removes both issues.
You can drop whole apples, pears, oranges, and other large fruits straight into the 3.5-inch wide chute — little to no slicing required. Long, fibrous ingredients like carrots, celery, or rolled kale go into the Auto-Cut Chute, and it processes them without clogging or backing up.
Kuvings clearly had celery drinkers in mind—especially the many people following medical programs who juice straight celery daily. Prep time is basically zero. Drop produce in one by one, the machine mostly self-feeds, and the pusher is rarely required.
What It Can Juice?
Despite being engineered with celery and carrots in mind, the REVO830 juices just about everything you throw at it. Soft fruits, firm fruits, hard vegetables, leafy greens — we tested them all.
Juicing Performance
We put the REVO830 through our full testing lineup — carrots, apples, celery, watermelon, leafy greens, pomegranate, oranges — and the results were consistently great across every category.
Carrots:
Good juice yield with very dry pulp. We’ve included photos below, and you can see how dry the pulp is.
Fruits:
If someone tells us they want a juicer mainly for fruit, we always recommend going with a vertical slow juicer — and the REVO830 is clearly one of the top-tier options in that category.
Watermelon juice came out with a good yield. Pomegranate pulp was impressively dry. And whole oranges dropped into the 3.5″ chute produced a bright, high-yield juice with almost no effort.
Celery:
This is really where the REVO830 sets itself apart. In our dedicated celery-juice test, it delivered the highest yield of any vertical juicer we’ve ever tested — right on par with the Sana 727, which is a green-juice specialist and our favorite single-auger horizontal juicer. We honestly didn’t expect a vertical juicer to compete that closely with the Sana, but the REVO830 did.
We have seen many juicers struggle with celery fibers. The REVO830 handled them cleanly, with no clogging or reverse needed.
Greens:
We fed wheatgrass and rolled kale through the Auto-Cut chute, and spinach through the wide chute. The results were far better than what we typically get from centrifugal machines.
Those high-speed juicers are great for hard produce like carrots, but with fruits and greens the pulp comes out so wet you’re basically losing money. With the REVO830, everything — even greens — came out dry.
Overall:
The REVO830 is genuinely versatile. It handled every type of produce we tested — fruits, veggies, greens, and especially celery — and the pulp stayed consistently dry exactly what you want from a premium slow juicer.
Juice Quality
Juice quality on the REVO830 is excellent. It runs at 50 RPM, so oxidation stays low and the juice tastes rich and full — exactly what you want from a cold-press machine. You can really taste the difference compared to high-speed juicers, which often make juice that feels a bit watery.
How Loud is it?
The REVO830 is much quieter than the high-speed juicers you find in department stores. Those machines can get loud fast — this one stays comfortably low. In our tests, it averaged around 67 dB, which is quiet enough to use early in the morning without waking everyone up.
Assembly
Assembly isn’t as instinctive as a fast juicer, and you’ll probably check the brochure the first time. But after doing it few times, you’ll get the hang of it.
Cleaning
Although this machine is excellent when it comes to juicing, it’s not the easiest to clean. It takes about 4–5 minutes, and a quick rinse alone won’t do the job.
The REVO830 does come with a unique cleaning brush, and this really helps. Kuvings is the only company that includes this style of brush. You place it around the juicing screen and spin it, and it scrubs the holes.
A simple cleaning tip we use:
Close the spout cap, pour in about 500 ml of water, turn the machine on, and let it rotate for a bit. Then open the spout to let the water out. This pre-rinse knocks off a lot of residue and makes the actual cleaning much easier.
What else it can do?
Kuvings includes both a smoothie strainer and a sorbet strainer with the REVO830, which gives the juicer more versatility than just cold-pressing juice.
Sorbet Strainer: This one is genuinely useful. You can run frozen bananas or mangoes to make healthy fruit sorbets with no added sugar. If you like frozen treats but want a healthier option than store-bought ice cream, this attachment is great.
Smoothie Strainer: You can make smoothies using the smoothie strainer, though I still think a blender is the better device for that job.
Warranty
Earlier Kuvings machines came with a 10-year warranty, but the REVO830 steps it up with a full 15-year warranty on all parts — one of the longest warranties in the home juicer industry. It’s a big reassurance. If anything breaks due to no fault of your own, you’re covered for the next 15 years.
Comparison with other recommended Juicers
Kuvings Revo830 vs Kuvings Auto10
Both machines cost the same, both are made in South Korea, and both are excellent — but they work differently.
The REVO830 is a traditional vertical juicer.
You feed produce one piece at a time, but the big advantage is that you don’t need to cut anything. Whole apples, whole carrots, whole celery — all go straight in.
The Auto10 uses a hands-free hopper.
You load the chamber, close the lid, and walk away while it pre-cuts and feeds everything. Most produce goes in whole, but celery still needs to be cut into shorter pieces. And if you want to fill the hopper efficiently, cutting produce into medium pieces helps you fit more in one batch.
So the trade-off is simple:
Auto10: minimal chopping for a few items, but fully hands-free juicing.
REVO830: zero chopping, but you stand and feed one by one.
Our Preference
Both are fantastic, and you can’t go wrong with either. For everyday convenience, we personally lean toward the Auto10, because loading the hopper and walking away fits our routine better.
If you want absolutely no chopping, or you mainly juice straight celery, the REVO830 is the better fit.
Kuvings REVO830 vs Sana 727
Both are premium South Korean juicers, but they’re designed for different priorities.
Sana 727 is a horizontal juicer and is leafy greens specialist. It is very easy to clean (about 1–1.5 minutes), but it does require pre-cutting because of its small feed chute. It’s not ideal for mostly-fruit juicing.
REVO830 is a vertical juicer and can juice all kinds of produce well, especially fruits. Cleaning takes longer (around 4.5 minutes), but the large feed chute makes everyday juicing easier.
Celery performance:
Both machines deliver the highest celery yield we’ve seen from any single-auger juicer, so you won’t go wrong with either.
Quick takeaway:
- Juice mostly leafy greens → get the Sana 727.
- Juice more fruits, or want zero prep → get the REVO830.
Final Words
The REVO830 isn’t cheap, but it’s a real investment in convenience and long-term reliability. If you’re tired of chopping celery or replacing lower-cost juicers every few years, this machine solves both problems. You can drop in whole apples, whole carrots, and whole celery stalks with little to no prep — and it simply works.
Built in South Korea and backed by a 15-year warranty, it’s designed for long-term use. If you want a powerful, low-prep, dependable slow juicer built to go the distance, the REVO830 remains an excellent choice.
