3i S10 Ultra Robot Vacuum and Mop Review
Bottom Line
Choose the 3i S10 Ultra for hands-off mopping, water recycling, and hard-floor convenience. Skip it if you need compact storage, consistently strong deep-carpet pickup, low energy use, or flawless obstacle avoidance.
Best for
Best for busy households with hard floors, pets, or frequent mopping needs that value reduced water handling and automated cleaning. It fits humid homes especially well because the water-production feature has more favorable evidence there.
Not for
Not for minimalists, apartment dwellers, or buyers who need a compact dock, low energy draw, flawless obstacle avoidance, or consistently strong deep-carpet cleaning. Dry climates may also reduce the benefit of the self-refilling water tank.
Verdict
Across the supplied reviews, the 3i S10 Ultra stands out less as a pure vacuuming champion and more as a convenience-first floor-care system. Reviewers repeatedly praised the WaterRecycle dock, roller mop, self-cleaning cycle, hard-floor pickup, pet-hair handling, and set-and-forget autonomy. The tradeoff is that its most distinctive hardware also brings drawbacks: a very large, heavy base, higher power use, audible dock operation, humidity dependence, and occasional wait time while water processes. Performance evidence is strongest for mopping and surface debris, while dried-on stains, crevice pickup, deep carpet cleaning, app polish, and obstacle avoidance were more inconsistent across reviews. It earns its strongest case in busy homes that value automation over compactness or low ownership complexity.

FAQ
Does the 3i S10 Ultra really avoid manual water refills?
Reviewers repeatedly said the WaterRecycle system reduced or eliminated manual water handling in humid conditions. Several also warned that drier rooms or humidity below about 30% may require manual refilling.
How good is the mopping performance?
The strongest evidence is for wet messes, daily mopping, and roller-mop convenience. Dried-on stains are more mixed, with some reviewers impressed and others finding below-average results.
Is it good on carpet?
Surface debris pickup on carpets can be good, but multiple test-heavy reviews criticized deep-cleaning and high-pile carpet performance. It is a better fit for hard-floor-heavy homes than carpet-first homes.
Is the app easy to use?
The app offers schedules, maps, cleaning modes, and customization, but reviewer sentiment is mixed. Some found it straightforward, while others called it clunky or missing expected controls.
Is it suitable for pet owners?
Most pet-related evidence is positive, especially for pet hair pickup and reduced roller tangles. Obstacle avoidance around pet messes is not consistent across reviews, so pre-cleaning risky objects may still matter.
How much space does the dock need?
Reviewers consistently described the dock and overall system as large and heavy. It needs a dedicated location and is not ideal for users who frequently move their robot vacuum system.
What maintenance remains?
The water system reduces dirty-water and clean-water tank chores, but reviewers still mention dust bags, filters, cleaning solution, onboard debris filters, and occasional dock or roller checks.
