Roborock QV 35A Robot Vacuum and Mop Review
Bottom Line
Choose the Roborock QV 35A for strong value, polished mapping, easy app control, and good everyday vacuum-mop upkeep. Skip it for heavy carpet hair, cable clutter, edge-perfect mopping, or fast heated drying.
Best for
Best for buyers who want an affordable robot vacuum-mop for routine hard-floor upkeep, accurate mapping, app scheduling, and low-effort dock maintenance. It fits homes where floors are prepped before cleaning and carpet hair is not the main challenge.
Not for
Not for households expecting upright-vacuum carpet performance, hands-off cable avoidance, edge-perfect mopping, or fast heated pad drying. It is also a weak fit for huge wet spills or heavy muddy messes.
Verdict
Reviewers describe the Roborock QV 35A as a strong budget-to-midrange robot vacuum and mop because it brings reliable lidar mapping, an intuitive app, auto-emptying, mop washing, and good everyday hard-floor cleaning into a lower price tier. The tradeoff is that it omits premium extras such as hot water washing, hot air drying, dirt detection, extendable edge hardware, and stronger object recognition. Evidence is strongest for mapping, app control, value, and routine mopping, while cable avoidance, corner reach, carpet hair pickup, odor management, and heavy muddy messes remain the main limits.

Cons
