Eufy Robot Vacuum Omni S1 Pro Review 2026: Worth Buying?

The eufy Robot Vacuum Omni S1 Pro arrived as eufy’s boldest experiment yet. It skipped the usual mop pads and used a spinning roller instead. It washed that roller with water jets while it cleaned. It even added an ozone generator to the water tank.

Two years later, the questions are still the same. Does the roller mop actually beat pads? Does the huge tower earn its space? And in 2026, with the S1 Pro now discontinued at eufy.com, does buying one still make sense?

This review covers both sides honestly, including the carpet problems most marketing pages skip. Keep reading before you spend a dollar.

In A Nutshell:

• Mopping is the star. The HydroJet roller applies about 1 kg of downward pressure and rinses itself constantly. It removed dried coffee and grape juice stains that pad based robots smeared around. It also handles large wet spills without streaking, because dirty water goes into an onboard tank.
• Carpet cleaning is the weakness. Surface debris pickup is fine. Deep embedded dirt is not. Independent lab testing scored it below average for carpet deep cleaning despite the 8,000 Pa rating.
• Obstacle avoidance is outstanding. The 3D MatrixEye binocular infrared system recognizes 100 objects and earned near perfect scores in testing. It dodged cables, socks, and pet bowls reliably.
• The station does almost everything. It empties debris into a 2.5L bag, washes and dries the roller, drains dirty water, refills clean water, and adds detergent automatically.
• The tower is tall and the app is basic. You cannot tuck the station under a counter. The MACH app lacks spot cleaning and mop direction controls.
• It is discontinued now. eufy pulled the S1 Pro in April 2026. Clearance pricing makes it tempting, but newer models exist.

eufy Robot Vacuum Omni S1 Pro

Last update on 2026-10-16 / Affiliate links / Images from Amazon Product Advertising API

The S1 Pro launched in June 2024 at $1,499.99. It was eufy’s flagship and it looked nothing like the competition. The robot itself is low and sleek with a glossy shell. eufy calls the styling Sportscar Streamlined, and honestly, it does look sharp next to the boxy competition.

Inside, the hardware is serious. You get 8,000 Pa of suction, a dToF internal LiDAR sensor, two side brushes, a floating main brush, and the HydroJet roller mop. The internal LiDAR keeps the robot profile low enough to slide under more furniture.

The headline feature remains the mopping system. Instead of dragging a damp pad across your floor, the S1 Pro spins a roller, sprays it clean with water jets, and squeezes the dirty water out with a squeegee. That water never touches your floor again.

Unboxing Experience And First Setup

The box is heavy. The station alone weighs a good chunk of the 30 pounds total, and you will want two hands to lift it out. eufy packs everything in molded cardboard trays rather than foam, which feels tidy and easy to recycle.

Inside you find the robot, the tall UniClean station, two dust bags, a spare roller mop, spare side brushes, an extra filter, a cleaning tool, and a sealed bottle of eufy floor cleaner. The spare parts bundle is genuinely generous. Most brands charge extra for this.

Setup took me under fifteen minutes. You clip in the side brushes, drop the roller into place, fill the clean water tank, install the detergent bottle, and plug in the station. The LCD panel on top of the station lights up and walks you through pairing. No tools needed anywhere.

Design And Build Quality

The robot feels premium. The shell has a smooth matte finish, the bumper has decent travel, and panel gaps are tight. Nothing rattles when you carry it.

The station is a different story. It stands tall, roughly like a small stick vacuum, and it carries the word MACH across the front. The smoked transparent plastic lets you half see the tanks inside. Some people love the look. I found it slightly cheap looking in daylight.

The bigger issue is practical. Height does not buy you a smaller footprint. The station takes up about the same floor space as shorter docks, so you lose the option to hide it under a counter or console table. Measure your spot before ordering.

On the plus side, the tall design puts the water tanks and touch controls at a comfortable height. Pulling the dirty tank out takes no bending at all.

HydroJet Roller Mop: The Real Highlight

This is why people buy the S1 Pro. The roller spins against your floor with about 1 kg of pressure, which beats most robots in this price band. Water jets rinse the roller continuously while it works.

The results speak for themselves. In my tests the S1 Pro lifted dried coffee rings and sticky grape juice on the first pass. Pad based robots I have used pushed that grime into a wider smear instead.

Large spills are the other win. A traditional mop pad saturates fast and then streaks everything. The S1 Pro pulls liquid into an onboard dirty water tank, so it keeps mopping with a clean surface. It handled a full cup of spilled water without leaving a haze.

Floors dry quickly too, because the squeegee removes most of the moisture as it goes.

Suction Power And Hard Floor Cleaning

On hard floors the S1 Pro performs very well. Bench testing showed suction around 1.45 kPa and airflow near 25 CFM, both comfortably above the average robot vacuum. That translates into real world pickup.

Two side brushes feed debris toward a floating main brush. Fine dust, rice, cereal, and larger crumbs all disappeared in a single pass across my tile and hardwood. Crevice pickup was decent, meaning the robot keeps a reasonable seal against flat surfaces.

Edges are less perfect. The S1 Pro does not have an extending side brush or a swing out arm, so it leaves a thin strip of dust along baseboards and in square corners. Newer robots with extending arms clean edges better.

One reviewer also noted the robot missed a single onion peel sitting in the middle of a kitchen floor after multiple passes. Odd misses happen occasionally.

Carpet Performance: Where It Falls Short

Here is the honest bad news. The S1 Pro is a hard floor specialist wearing a flagship badge.

The roller lifts 12.7 mm when it detects carpet, which is higher than the 10 mm average. Good. Surface level debris on low pile carpet came up fine. Also good.

Deep cleaning is the problem. In controlled carpet deep clean testing, the S1 Pro scored below average and repeated runs at maximum power did not fix it. Embedded sand and fine grit stayed in the fibers. For a robot with an 8,000 Pa rating, that is disappointing.

Long pile rugs cause a second issue. Despite lifting the mop, the robot got physically stuck on shaggy carpets more than once. You will want to draw no go zones around thick rugs in the app.

Pet hair on low pile carpet was also mediocre rather than great.

Navigation, Mapping And Coverage

Navigation is one of the S1 Pro’s strong suits. The dToF LiDAR sits inside the chassis, so the robot stays low while still building an accurate map.

First mapping run took a few minutes and the layout came out clean and correct across two floors. Multi level maps work reliably, which matters if you carry the robot upstairs.

Coverage efficiency tested above average. A roughly 38 square meter floor plan finished in about 45 minutes with tidy parallel lines and few repeated passes. The robot rarely got confused about where it had been.

Room editing in the app is simple. You split, merge, and name rooms with a few taps. You can also set cleaning preferences per room rather than per run, and you can order which room gets cleaned first. That is a smarter system than most competitors offer.

3D MatrixEye Obstacle Avoidance

If you have kids, pets, or a floor full of charging cables, this section matters most.

The S1 Pro uses active binocular infrared imaging that eufy brands as 3D MatrixEye. It recognizes 100 object types and builds a depth map of the room instead of guessing from a flat photo.

Performance here is exceptional. Testing gave it a near perfect obstacle avoidance score, among the best results recorded for any robot vacuum. In my home it avoided phone cables, slippers, a dog bowl, and a laundry pile without a single tangle or collision.

The app also lets you tune sensitivity. There is a Tiny Obstacle Avoidance toggle that helps if clumps of pet hair keep triggering false stops. Turning it off made cleaning smoother in my hallway.

Infrared also means the system works in complete darkness, which camera only robots cannot do.

Inside The UniClean Station

The station handles nearly all maintenance for you. When the robot docks, debris empties into a disposable bag that holds up to 65 days of dirt, based on a 2.5L capacity.

It then washes the roller mop, dries it with warm air, drains the onboard dirty water, refills the clean water tank, and mixes in floor cleaner from the 600 ml detergent bottle. You do almost nothing daily.

The clever bit is the built in ozone generator in the clean water tank. eufy claims it removes up to 99.99% of bacteria like E. coli when used as directed. I cannot verify lab claims at home, but the mop smelled fresh rather than musty after weeks of use, which is more than I can say for some pad based docks.

Touch controls on top of the station let you start cleaning without your phone.

MACH App Features And Missing Options

The MACH app is separate from the standard eufy Clean app, which is annoying if you already own other eufy products. Once you accept that, it works well.

You get scheduling, virtual barriers, no go zones, no mop zones, suction levels, water levels, station behavior toggles, and remote control. The interface is clean and responsive. Per room settings remain my favorite feature.

Some notable gaps exist. There is no pin and go spot cleaning, which many rivals include and which I use constantly. There is no onboard camera feed for remote viewing. You also cannot set the mop to follow the grain of hardwood, and you cannot manually control mop lifting behavior.

Roborock and Ecovacs apps simply offer more. If app depth matters to you, this may sting.

Battery Life, Noise And Daily Use

eufy rates the battery at 184 minutes in quiet mode. Real world numbers land lower once you use higher suction and mopping together, but I still finished a full 1,500 square foot single level on one charge with power left over.

The robot recharges and resumes automatically if it runs out mid job. Charging is reasonably fast thanks to the upgraded station.

Noise is acceptable in standard mode and loud in maximum mode. The station is the noisy part. Auto emptying produces a short blast that will interrupt a phone call, and mop drying runs a fan for a while afterward.

Daily living is mostly hands off. I emptied the dirty water tank about once a week and changed the dust bag roughly every two months with one shedding dog in the house.

Pet Hair And Tangle Resistance

Pet owners get a mixed result. Obstacle avoidance means the robot will not eat your dog toys or run through an accident, and that alone prevents a lot of horror stories.

Pickup on hard floors is strong. Fur, dander, and dust bunnies vanish from tile and wood easily. Low pile carpet is much weaker, and thick fur woven into fibers often stays put.

Tangling is the other consideration. The S1 Pro does not use the newest anti tangle spiral brush design that eufy later added to models like the E28 and S2. Long human hair wrapped around the main brush during my testing, and I trimmed it free with scissors about every two weeks.

If you own a heavy shedding pet and lots of carpet, look at a newer model instead.

Maintenance Needs And Running Costs

Ongoing costs deserve attention because they are higher than average here.

The detergent system uses eufy branded sealed bottles only. You cannot pour in your own cleaning solution like you can with several competitors. That locks you into buying refills from eufy at eufy prices.

Dust bags are a recurring cost too, though a 2.5L bag lasting up to 65 days keeps that reasonable. Filters, side brushes, and the roller mop all need periodic replacement. The generous in box spares delay your first purchase by several months.

Manual jobs still exist. You rinse the station tray occasionally, wipe sensors, clear hair from the brush, and refill clean water every few runs. Budget roughly ten minutes of attention per month.

Now that the model is discontinued, eufy confirms accessories remain available and support continues for owners.

What The eufy Omni S1 Pro Does Not Do Well

An honest review needs a plain list of failures. Here they are.

Deep carpet cleaning is genuinely weak. Repeated maximum power runs did not pull embedded grit out of medium pile carpet. Do not buy this robot for a carpeted home.

Long pile rugs trap it. Even with mop lifting, the chassis beaches itself on shaggy pile.

Edge cleaning leaves a visible dust line because there is no extending brush or arm.

The station is tall and cannot hide under furniture.

The app misses spot cleaning, mop direction control, and manual mop lift settings.

Detergent is proprietary and sealed.

Hair tangles on the main brush if you have long hair or a shedding pet.

And one reviewer flagged occasional odd misses, like leaving a piece of debris sitting in the open after several passes. It is very good, not flawless.

Pros And Cons Of The eufy Omni S1 Pro

Pros

• Best in class mopping thanks to the self rinsing HydroJet roller and 1 kg of pressure
• Handles large wet spills without streaking because dirty water goes onboard

• Discontinued by eufy in April 2026

Price, Value And Discontinuation In 2026

This is the part that changes everything. eufy officially discontinued the S1 Pro in April 2026, and the standard S1 followed in June 2026. It is no longer sold on eufy.com in the United States.

That matters two ways. First, remaining stock sells at steep clearance pricing, sometimes near $500 to $600 versus the original $1,499.99. At that price the mopping performance becomes a bargain.

Second, you are buying older hardware. eufy’s newer S2 offers 30,000 Pa suction, HydroJet 2.0, anti tangle brushes, and 200 object recognition. The E28 adds a detachable portable deep cleaner.

eufy promises lifetime customer support and continued accessory availability for S1 Pro owners, which softens the risk considerably. Still, warranty coverage runs twelve months from purchase, so buy from a reputable seller.

Who Should Buy The eufy Omni S1 Pro

Buy it if your home is mostly hard floors. Tile, hardwood, vinyl, and laminate are where this robot shines, and the roller mop genuinely outperforms pad based rivals on dried stains and spills.

Buy it if you have a messy floor environment. Cables, toys, shoes, and pet bowls do not faze the obstacle avoidance system. Parents and pet owners with hard floors get real peace of mind.

Buy it if you find it deeply discounted. At clearance pricing the mopping value is hard to match.

Skip it if your home has significant carpet. Skip it if you own long pile or shaggy rugs. Skip it if you want the newest anti tangle hardware or a deeper app.

For carpet heavy homes, the newer eufy S2 or a Roborock flagship will serve you better.

FAQs

Is the eufy Omni S1 Pro still available in 2026?

Not from eufy directly in the United States. eufy discontinued the S1 Pro in April 2026. You can still find remaining stock through Amazon and other retailers, often at clearance prices. eufy confirms that accessories remain available and that support continues for existing owners.

How good is the S1 Pro on carpet?

Average at best. It picks up surface debris fine, but independent testing rated its deep carpet cleaning below average. It also risks getting stuck on long pile rugs. Treat it as a hard floor robot.

Does the mop really clean itself while running?

Yes. Water jets spray the spinning roller continuously and a squeegee scrapes dirty water into an onboard tank. That is why it avoids streaking on big spills.

Can I use my own floor cleaner?

No. The station accepts sealed eufy branded detergent bottles only. You cannot substitute third party solutions, which raises long term running costs.

What is the ozone generator for?

It treats water in the clean tank. eufy claims it removes up to 99.99% of bacteria such as E. coli in lab conditions when used as directed. Real world results vary by home.

Does it work in the dark?

Yes. The obstacle avoidance uses active infrared imaging rather than a standard camera, so it detects objects reliably even with all lights off.

How often do I need to touch it?

Very rarely. Empty the dirty water tank about weekly, change the dust bag every two months, and trim hair off the main brush every few weeks.
