The Omega VSJ843 is the vertical pick in my celery juicer guide, at $330.99. It is an upright slow juicer: an auger turning at 43 RPM presses produce against a screen, pulp leaves through its own outlet, and a flap on the spout holds juice in the bowl until you open it.
Amazon shows 4.3 stars across 1,953 ratings. Filtering to this listing leaves 492 written reviews, and 140 of those are critical.
Owners who get on with it praise dry pulp and quiet running. The critical reviews centre on jams with fibrous produce, a hopper that locks onto the bowl so tightly some owners reach for pliers, and machines that stop working.

What Comes in the Box
The manual lists the pusher, hopper, auger, screen, spinning brush with its silicone wipers, juice bowl, motor base, pulp container, juice cup and a cleaning brush.
Amazon’s included-components field says only “Juicer”, so check the parts against that list on arrival. Two critical owners describe units that arrived used or damaged, one with dried produce still inside.
The listing gives the warranty as 15 years on the motor and one year on parts. Omega’s warranty policy adds that owners pay the shipping on replacement parts, that lids and gaskets count as consumables, and that cover applies only to the original purchaser.

What 43 RPM and Omega’s Own Numbers Tell You
43 RPM is the point of the design. A slow auger crushes and presses produce rather than shredding it against a fast-spinning basket. My masticating vs centrifugal comparison covers the trade-off.
The numbers do not all agree. The Amazon listing says 150 watts and the manual says 250 watts rated consumption. Omega’s product image puts the footprint at 7 by 8.5 inches and the manual at 7 by 10. Either way, it takes far less counter depth than a horizontal slow juicer.
It is not built for long sessions. The manual says not to run it for more than 30 minutes at a time, then to let it cool for 5 minutes. For a morning glass that never matters; for batch juicing a week of bottles it does.
The rating needs care. 140 of the 492 written reviews for this listing are critical, or 28%, and 80 are one star. That is a larger critical share than the 4.3 average suggests.
Who It’s For
- Anyone juicing a glass or two at a time who wants dry pulp. Dry pulp is among the most repeated praise, including from owners who have had other juicers.
- Kitchens short on counter depth. It stands upright on a base about 7 inches wide.
- Early-morning juicers in shared homes. Quiet running comes up again and again in the positive reviews.
- People willing to cut celery and other stringy vegetables small. Omega’s manual asks for 1 to 2 inch pieces.
- Anyone who washes the parts straight after juicing, which is what keeps the hopper from locking on.
Who Should Look Elsewhere
- Batch juicers. The 30-minute operating limit and the time spent cutting produce small both work against big sessions.
- Anyone who wants to drop whole produce in. Owners repeatedly report cutting carrots, celery and apples into small pieces to stop it jamming.
- Buyers on a budget. The Omega Cold Press All-in-One is $199.87 and the Ninja NeverClog JC151 is $149.95.
- Anyone counting on the warranty to be painless. Owners describe unanswered emails and replacement parts whose shipping cost more than the part, which matches Omega’s policy that owners pay shipping.
- People who leave the juicer assembled with pulp inside. Several owners describe a hopper they could not unscrew.
Performance
Juice and pulp
Dry pulp is among the praise that recurs most. One owner says the pulp from ginger was dry enough to use as kindling; another, who had tried other juicers, likes this one best because it extracts a lot of juice and the pulp comes out near dry.
Not every owner sees that. A critical owner found wet pulp and pulp in the juice, and another, after three years, says its moist carrot pulp and juice are no better than their earlier $100 juicer. One owner notes that softer fruit leaves wetter pulp and runs it through a second time.
Hard produce such as carrots, beets, apples, ginger and cucumber comes up most in the positive reviews.
Celery, greens and jams
Jams are the most specific complaint. Owners describe the auger stalling on small pieces of carrot, fibrous produce wrapping around it, and having to stop mid-batch to clear it. One says celery’s long fibres bind inside the machine.
Omega’s manual expects this. It tells owners to cut celery, fennel and other stringy stalks into 1 to 2 inch pieces, and to hold REV for a few seconds, then restart, if the auger stops. Positive reviewers who juice celery say the same thing: cut it small and feed it slowly.
If a slow juicer keeps stalling, my guide to why a juicer clogs covers the usual causes before you call support.
The hopper that will not come off
The hopper screws clockwise onto the juice bowl, and several owners report it locking on. One owner cannot take it apart without help as the base screws itself tighter during use; another needed channel-lock pliers; a third uses a clamp and a wrench.
One critical owner, a month outside the warranty, says the hopper threads jumped their track and the assembly is now stuck for good.
The manual’s advice for a hopper that will not open is to run the motor to clear pulp, press REV, and not to force it. Taking it apart soon after juicing, before pulp dries, is the habit most likely to avoid the problem.
Cleaning
Cleaning divides owners. Several positive reviews call it easy to clean, some once they have learned how it comes apart, while others say rinsing, washing and drying the parts is the one drawback, and that the screen basket is hard to scrub.
Between juices, the manual says to close the flap, pour water through and run it, then wash the full bowl set at the end of the day. The spinning brush wipes the inside of the screen as it turns, which Omega calls its auto cleaning system.
The listing calls the parts dishwasher safe and the manual shows both a hand-wash soak and the top rack of a dishwasher. My guide on how to clean a juicer covers screens and augers.
Design and Build
It is a silver and black upright machine: a tall black feed chute and pusher on top, a clear juice bowl with a measuring scale, the pulp outlet on the left, the spout and its flap on the front, and a rocker switch on the side.
It weighs 11.5 pounds, and the manual says to lift it by the base with both hands rather than by the bowl.
The manual calls some shaking normal with hard produce such as carrots and beets. Its troubleshooting page puts juice leaking over the base down to overfeeding, which pushes the seal aside, or a juice flap left open.
What Owners Report
Of the 492 written reviews filed under this listing, 298 are five stars and 80 are one star; 352 are positive and 140 critical. The themes below each appear in more than one unconnected review.
What recurs in the positive reviews
- Dry pulp. Owners describe pulp coming out near dry, especially from hard produce.
- Quiet. Quiet running comes up in dozens of positive reviews.
- Juice quality. Smooth juice with little pulp, by owner accounts.
- Longevity for some. Owners report years of regular use, one at three years.
- Easy once learned. A learning curve to assemble, then simple to use and clean for many.
What recurs in the critical reviews
- Jams. Stalling on fibrous or hard pieces unless produce is cut small.
- A hopper that locks on. Owners needing pliers, clamps or help to unscrew it.
- Failures. Machines that stopped after 15 uses, within a year, or once out of warranty.
- Used or damaged on arrival. Broken lids and dried produce inside.
- Wet pulp for some. Pulp in the juice and moist pulp from carrots.
- Warranty service. Unanswered emails and parts that cost more to ship than to buy.
- Cleaning time. Several parts to wash and a screen that is hard to scrub.
The reviews split by how the machine is used. Owners juicing hard produce in modest amounts, cut small and cleaned straight away, rate it highly; owners pushing stringy greens through it, or leaving it assembled, meet the jams and the stuck hopper.
Value
At $330.99 the VSJ843 costs $131 more than the Omega Cold Press All-in-One at $199.87, a horizontal slow juicer with a longer body, and $181 more than the Ninja NeverClog JC151 at $149.95.
What the extra buys is an upright footprint and continuous pulp ejection at 43 RPM. It does not buy a better owner record: 28% of the written reviews for this listing are critical.
The price moves. My celery guide recorded it at $308.99 in June and $334.99 in August, and the listed price is $399.99, so it is worth checking before buying.
Durability
Durability reports cover the whole range: owners still using theirs after three years, and others whose machines stopped after 15 uses, within a year, or once out of warranty.
The 15-year motor warranty is the listing’s strongest reassurance, but parts are covered for one year, owners pay shipping on replacements, and Omega classes lids and gaskets as consumables. Register it and keep the receipt.
Two habits in the manual are within your control: stop within 30 minutes and let the motor cool, and cut stringy produce small so the auger is not forced.
None of this is a failure rate. Unhappy owners write more reviews than happy ones, and 492 reviews is a modest sample for a machine sold this long.
Alternatives to Consider
- For a horizontal Omega at much less money, my Omega Cold Press juicer review covers the All-in-One.
- For the cheaper cold press pick in the celery guide, see my Ninja NeverClog JC151 review, and for a hands-free premium machine, my Nama J2 review.
- If you are not sure juicing will stick, my Hamilton Beach Big Mouth review covers a $74.95 centrifugal starter.
- For the full field, see my best juicer guide and best juicer for greens, and the juicers hub collects everything else.
Verdict
The Omega VSJ843 is a quiet upright slow juicer that owners credit with dry pulp and smooth juice, and it fits a counter a horizontal slow juicer would not.
Against that, it costs $330.99, 28% of its written reviews are critical, and those reviews keep returning to jams with fibrous produce, a hopper that locks on, and machines that stop. Cut produce small and clean it straight away, and many of those problems look avoidable; the failures do not.
Six out of ten: marked up for pulp, noise and footprint, marked down for price, jams, the stuck-hopper reports and warranty friction.
How This Review Was Put Together
Plainly: this is research-based, not a hands-on test. I have not owned or used this juicer, and nothing here should be read as a report from my own kitchen.
What it rests on: the published specification — the speed, motor, auger, dimensions, operating limit and parts Omega lists on Amazon and in the VSJ843 user manual, and the terms of Omega’s warranty policy — read against the other juicers in my celery juicer guide; the split of the 492 written reviews filed under this exact listing rather than the 4.3 average across 1,953 ratings; and the text of the positive and critical reviews, read for themes that recur across independent owners.
Why owner reviews are treated as evidence here: one reviewer cooking on one unit for a fortnight cannot show whether a hopper that locks solid or a motor that stops after a year is one bad unit or a pattern. Several hundred owners writing over several years can at least show which problems repeat. A theme is only reported above where more than one unconnected owner raised it.
What I could not establish: which of Omega’s two wattage and two depth figures is current, since the manual dates from 2014; whether the 1,953 pooled ratings include other colours of this model; and what share of units fail, since unhappy owners are over-represented in written reviews.
Price, stock and ratings were read from Amazon’s US marketplace on 15 September 2026 and will move.
Frequently Asked Questions
Is the Omega VSJ843 good for celery juice?
It can juice celery, but Omega’s manual says to cut celery into 1 to 2 inch pieces, and owners report the long fibres binding the auger when pieces are larger. Feed it slowly and use REV if it stalls.
How fast does the Omega VSJ843 turn?
43 RPM, according to both the listing and the manual.
Why won’t the hopper come off my Omega vertical juicer?
Several owners report the hopper locking onto the bowl. The manual says to run the motor to clear pulp, press REV to push stuck food up, and not to force it, and to contact Omega if it still will not open.
How long can the Omega VSJ843 run at a time?
Under 30 minutes at a time, according to the manual, followed by 5 minutes to let the motor cool.
Is the Omega VSJ843 dishwasher safe?
The listing says the parts are dishwasher safe, and the manual shows both a hand-wash soak and the top rack of a dishwasher. Owners are split on how easy it is to clean.
What is the warranty on the Omega VSJ843?
15 years on the motor and one year on parts, according to the listing. Omega’s policy says owners pay shipping on replacement parts and that lids and gaskets count as consumables.
Omega VSJ843 or the Omega Cold Press All-in-One?
The VSJ843 is upright and takes less counter depth. The All-in-One is a horizontal machine at $199.87 with nut butter and pasta attachments. Both are slow juicers; the choice is mostly footprint against price.
What comes in the box?
The juicer, pusher, hopper, auger, screen, spinning brush, juice bowl, pulp container, juice cup and a cleaning brush, according to the manual.
