The eufy Omni S1 Pro does one thing better than almost every robot vacuum we have tested: mop hard floors. Its roller mop system pushes down with 1 kg of force — enough to scrub dried coffee stains in two passes. And when you combine that with the self-washing roller, ozone sanitization, and a 10-in-1 dock that handles everything automatically, you get the most hands-off hard floor cleaning experience available.
But there is a catch. Carpet cleaning is genuinely weak — it scored below average in Vacuum Wars' deep clean tests, consistently earning some of the lowest carpet scores. If your home has significant carpet coverage, this is the wrong robot.
At $849.99 on sale (down from the \$1,499 MSRP), the S1 Pro is a focused tool: exceptional on hard floors, disappointing on carpet. Know what you are buying, and it will not disappoint.

Design & Build
The S1 Pro is a sleek robot — at just 96 mm tall (3.78 inches), it slides under most couches and bed frames. The matte black body with a subtle eufy logo looks understated compared to the bulkier designs from Ecovacs and Dreame.
The real engineering is underneath. Instead of spinning mop pads, eufy uses a roller mop that spins continuously while the robot moves. The roller self-washes during cleaning — dirty water gets scraped off and clean water is applied — so you are never dragging dirty water across the floor. This is the same approach as the Ecovacs X9 Pro Omni, but eufy's implementation is more compact.
The UniClean dock is the 10-in-1 station that handles: auto-emptying, mop washing, mop drying with hot air, water tank refilling, cleaning solution dispensing, ozone sanitization, wastewater collection, and LCD touch control. It is large — plan for dedicated floor space — but you genuinely do not need to touch it for weeks at a time.
One design concern from long-term users: the rear water receptacle has a plastic component that can crack after several months, causing water leaks. eufy has acknowledged this in warranty claims, but it is worth monitoring.
Navigation & Mapping
Navigation is a genuine strength. The S1 Pro uses internal LiDAR — meaning the sensor is hidden inside the body rather than mounted on a turret. This contributes to the slim 96mm profile while delivering accurate room mapping.
The active binocular infrared obstacle avoidance is outstanding. RTINGS gave it a perfect score for obstacle avoidance, with a 100% success rate dodging simulated pet waste. In daily use, it avoids cables, shoes, pet toys, and furniture legs with precision.
Room mapping is accurate on the first run. The eufy app shows a clean 3D map with automatic room labeling. Zone cleaning, no-go areas, and scheduling all work reliably. The app itself is polished — TechRadar specifically praised it as "excellent," with a clean interface and intuitive controls.
Cleaning Performance
Hard floors: Excellent. The 8,000Pa suction is more than adequate for smooth surfaces — crumbs, flour dust, pet food, coffee grounds all get picked up in a single pass. One Homes & Gardens reviewer reported the S1 Pro "reduced my canister vacuum use by 90%." For daily maintenance cleaning on hardwood, tile, or laminate, it is one of the best.
Carpet: Below average — genuinely weak. This is the S1 Pro's most significant flaw. In Vacuum Wars' carpet deep clean evaluation, it scored below average — and when tested multiple times in different configurations, it "consistently earned some of the lowest scores." Carpet pet hair pickup averaged about 65%, compared to 90-100% from competitors like the Dreame L50 Ultra.
The reason is simple: 8,000Pa of suction is fine for hard floors but insufficient for pulling embedded debris from carpet fibers. The roller mop also does not help on carpet — it lifts automatically, but the vacuum alone cannot compensate.
Bottom line: If your home is all hard floors, the S1 Pro is exceptional. If you have even one room with medium or thick carpet, look elsewhere.
Mopping Performance
Mopping is the S1 Pro's superpower. The roller mop spins at high speed while pushing down with 1 kg (2.2 lbs) of force — significantly more pressure than dual spinning pad systems. The result is genuine scrubbing, not just wiping.
In testing against dried-on stains — coffee, grape juice, muddy paw prints — the S1 Pro outperformed most competitors. Dried coffee came up in two passes. Fresh spills disappeared in one. The always-clean mop design means the roller self-washes during cleaning, so dirty water never touches clean floor.
The HydroJet system sprays water ahead of the roller for even coverage. Combined with the ozone sanitization in the dock, floors are not just clean — they are genuinely sanitized.
One drawback: eufy requires you to use their proprietary cleaning solution. Third-party solutions may void the warranty and potentially damage the roller. A bottle lasts about 30 cleans and costs \$15-20 to replace. This adds to ongoing costs compared to robots that work with plain water.
Battery & Noise
Battery life is adequate at 170 minutes on standard mode — enough for most hard floor homes under 2,000 sq ft. The 4,600mAh battery is smaller than the 6,400mAh cells in Dreame and Ecovacs flagships, which explains the shorter runtime.
On max suction, expect about 90-100 minutes — more than enough for daily hard floor cleaning but limiting if you need deep cleaning of a large home.
Noise is pleasantly low at about 65 dB on standard mode. One reviewer compared quiet mode to "the volume of a washing machine wash cycle" — barely noticeable from another room. Max mode is louder ("like a hair dryer"), but you rarely need max on hard floors.
App & Smart Features
The eufy Clean app is one of the best in the industry. TechRadar specifically called out "outstanding" app quality with a clean interface, intuitive room controls, and reliable scheduling.
Features include room-by-room cleaning, adjustable suction and mop wetness per room, no-go zones, virtual walls, and detailed cleaning history. The 3D map view shows the robot's position in real time.
Voice control works through Alexa and Google Assistant. No Matter support yet — if you need Apple HomeKit integration, the Ecovacs X9 Pro Omni is the only roller-mop competitor with Matter.
The dock's LCD touch screen adds a nice physical interface for quick commands without opening the app.
Maintenance & Running Costs
RTINGS specifically flagged the S1 Pro's recurring costs as high — and we agree.
The proprietary cleaning solution is the main ongoing expense. A bottle costs \$15-20 and lasts about 30 cleaning cycles. Over a year of daily cleaning, that adds up to approximately \$180-240 just for solution.
The roller mop lasts about 3-4 months before needing replacement (\$20-25 each). The dustbin is bagless and washable — a plus that saves money. Side brushes need replacement every 3-6 months (\$10-15).
Total annual maintenance cost: approximately \$250-350 — significantly higher than competitors that work with plain water. This is the S1 Pro's hidden cost, and it is worth factoring into your purchase decision.

Who Should Buy the eufy Omni S1 Pro
Buy it if:
- Your home is primarily hard floors (hardwood, tile, laminate) with minimal carpet
- Mopping quality is your top priority — the roller system is one of the best
- You want a truly hands-off experience — the 10-in-1 dock handles everything
- You prefer a compact robot that fits under low furniture (96mm tall)
Skip it if:
- You have medium or thick carpet anywhere in your home — performance is genuinely poor
- You want to avoid proprietary consumables — the required cleaning solution adds \$180-240/year
- You need Apple HomeKit / Matter support — not available
- You want maximum suction — 8,000Pa is adequate for hard floors but weak for everything else
The Verdict
8/10The eufy Omni S1 Pro is a specialist — and a very good one. Its roller mop system delivers some of the best hard floor mopping we have tested, the obstacle avoidance earned a perfect score, and the eufy app is genuinely excellent. But the carpet cleaning weakness is real and significant — this is not an all-rounder. If your home is all or mostly hard floors, the S1 Pro at $849.99 is an excellent value. If you need carpet performance too, the [Dreame L50 Ultra](/reviews/dreame-l50-ultra-review) or [eufy X10 Pro Omni](/reviews/eufy-x10-pro-omni-review) are better all-around picks.

Frequently Asked Questions
Is the eufy Omni S1 Pro worth it?
For hard floor homes, absolutely. The roller mop system delivers some of the best mopping performance available, the obstacle avoidance is perfect, and the 10-in-1 dock is genuinely hands-free. At sale prices around $849.99, it is excellent value. Just be aware of the high recurring costs for the proprietary cleaning solution (\$180-240/year) and the weak carpet performance.
How does the eufy S1 Pro compare to the Ecovacs X9 Pro Omni?
Both use roller mop systems, but the X9 Pro Omni has significantly stronger suction (16,600Pa vs 8,000Pa), better carpet cleaning, and Matter/HomeKit support. The S1 Pro wins on obstacle avoidance (perfect RTINGS score), app quality, and lower profile (96mm vs 98mm). The X9 Pro is the better choice if you have mixed floors; the S1 Pro is the better specialist for hard-floor-only homes.
Can the eufy S1 Pro clean carpet?
Technically yes, but performance is genuinely below average. In Vacuum Wars' carpet deep clean tests, it consistently scored among the lowest. Pet hair pickup on carpet averaged only 65%. The roller mop automatically lifts on carpet, but the 8,000Pa suction alone is insufficient for embedded debris. If you have carpet, choose a different robot.
Does the eufy S1 Pro require special cleaning solution?
Yes — eufy requires their proprietary cleaning solution for the roller mop. Using third-party solutions may void the warranty. A bottle costs \$15-20 and lasts about 30 cleans. For daily cleaning, budget approximately \$180-240 per year. This is significantly higher than competitors that work with plain water.
How does the eufy S1 Pro compare to the eufy X10 Pro Omni?
The S1 Pro is the mopping specialist — its roller mop outperforms the X10 Pro's spinning pads on dried stains. The X10 Pro is the better all-rounder — stronger carpet cleaning, better pet hair pickup, and no proprietary solution requirement. If your home is all hard floors, get the S1 Pro. If you have mixed floors, get the X10 Pro.
