Roborock Q Revo MaxV vs 3i S10 Ultra
Quick take: The 3i S10 Ultra has stronger suction (13,000 vs 7,000 Pa).
Which one to buy
At the same $700, this comes down to how much you hate handling water. The 3i S10 Ultra's dock distills its own dirty mop water and pulls moisture out of the room air to refill the clean tank, so in a humid house owners go weeks or months without touching a tank. The Q Revo MaxV runs a conventional all-in-one dock: you fill and drain, but it washes its spinning pads with hot water, which the 3i does not.
3i owners confirm the recycling works, and they praise how it swallows big debris and how its roller mop handles wet spills. The trouble is everything around it. The most repeated complaint is a musty, mildew smell from the water system that some owners never shake. Others find it hung on a threshold or sitting idle just off the dock instead of finishing the job. It's weak on dried-on stains, below average on deep carpet despite its 13000 Pa rating, and the dock ships at over 80 pounds with a compressor that hums between runs. Below about 30% humidity the self-refill stops and you're filling the tank by hand anyway.
The Q Revo MaxV is the safer machine. Owners call it the sweet spot in Roborock's lineup: obstacle avoidance that reliably dodges cables, shoes and pet toys, an app with strong per-room control, and spinning pads that press hard enough to lift dried spots. Its faults are ordinary ones. The 7000 Pa drops off on thick carpet, the bristle-and-rubber brush tangles with long hair, a few owners see circular streaks on dark floors, and its dock is large too.
For most homes the Roborock was the better $700, because it does everything well and has fewer ways to disappoint, but it is now discontinued; Roborock's successor is the Qrevo 2 Pro at $650. The 3i earns its place in one specific house: humid, mostly hard floors, a corner big enough for the dock, and an owner who would rather manage an occasional smell than ever carry a water tank again.
Roborock Q Revo MaxV
For a typical mixed-floor home with a pet or two and the usual cables on the floor, it's the lower-risk $700, with hot-water pad washing and obstacle avoidance owners trust; now discontinued, with the Qrevo 2 Pro as its successor.
3i S10 Ultra
Only worth it in a humid home with mostly hard floors and space for a dock that ships at over 80 pounds, where never refilling or draining a tank matters more than stain removal.

Roborock Q Revo MaxV vs 3i S10 Ultra: common questions
Does the 3i S10 Ultra's water recycling still beat the Q Revo MaxV in a dry climate?▾
Not really. Owners say the dehumidifier needs roughly 30% humidity or more to top up the tank, so in a dry house or a heated winter you refill the 3i by hand just like the Q Revo MaxV. At that point you've kept the big dock and the odor risk while losing the main reason to buy it.
Which handles dried-on stains better, the Roborock Q Revo MaxV or the 3i S10 Ultra?▾
The Q Revo MaxV. Its owners say the dual spinning pads press harder than older vibrating systems and lift dried spots well. The 3i scored poorly on dried-on stains in testing, although its owners say the roller mop does better than spinning pads on fresh wet spills.
Is the 3i S10 Ultra noisier to live with than the Q Revo MaxV?▾
While cleaning they're rated almost the same, 66 dB for the 3i and 67 dB for the Roborock. The difference is between runs: the 3i's dehumidifier compressor hums like a fridge, and owners advise keeping its dock away from a bedroom or desk.
