Roborock Qrevo S vs Roborock QV 35A
Quick take: The Roborock QV 35A costs $70 less; the Roborock QV 35A has stronger suction (8,000 vs 7,000 Pa).
Which one to buy
The QV 35A is essentially the Qrevo S updated, and it costs $70 less. The Qrevo S is now discontinued, so there's little reason to pick it here. Both use the same kind of dock (auto-empty, mop washing in unheated water, refills, drying), dual spinning mops at 200 RPM, a 10 mm mop lift, a 330 ml bin, a 180-minute battery and the same Roborock app. The QV 35A adds a step in suction, 8000 Pa against 7000 Pa, and it lists obstacle avoidance the Qrevo S lacks.
Owners describe the two in similar terms. Qrevo S owners call it reliable with great mopping, pads that lift over carpet and weeks of hands-free running, but say it eats cables, is weak on carpet, and can jam on long pet hair. QV 35A owners say the mops lift sticky spots, the anti-tangle roller stays clear of cat hair, and six-month owners touch it only to swap the bag. Their complaints: robot and dock are loud, hair still gathers at the brush end caps, heavy hair can clog the auto-empty port, and medium or thick carpet edges come out damp. A few early owners had dock flooding traced to badly seated tanks or damaged gaskets, so seat both tanks firmly and check the gaskets on delivery.
Neither suits thick carpet or a floor covered in cords. For everything else, the QV 35A gives you the same experience, a little more suction and a model that's still sold, for less money.
Roborock Qrevo S
Only worth it if you find one discounted well below the QV 35A, since it's discontinued and its newer sibling does the same job for $70 less.
Roborock QV 35A
For a mostly hard-floor home with rugs that wants a full self-maintaining dock on a budget, it's the current version of this robot and the cheaper one.

Roborock Qrevo S vs Roborock QV 35A: common questions
Is the Roborock QV 35A just a newer Qrevo S?▾
Close to it. The QV 35A keeps the Qrevo S's dock routine, 200 RPM spinning mops, 10 mm mop lift and 180-minute battery, adds a bump from 7000 Pa to 8000 Pa, and costs $70 less. With the Qrevo S discontinued, the QV 35A is the one to get.
Do the Qrevo S and QV 35A both struggle with cables on the floor?▾
Yes. Qrevo S owners say it eats cables because it has no camera. The QV 35A's obstacle avoidance is sensor-based too, and it can still swallow phone cables and socks, so pre-tidy the floor with either one.
Will the QV 35A or Qrevo S keep my medium-pile rugs dry while mopping?▾
Low-pile rugs stay dry on both thanks to the 10 mm lift. QV 35A owners with medium or thick pile report damp carpet edges, and the Qrevo S uses the same lift height, so plan separate vacuum-only runs or no-mop zones for plusher carpet.
