Roborock Qrevo Curv 2 Flow review

The Qrevo Curv 2 Flow is Roborock's answer for hard-floor homes, and at $649.99 when checked it is the cheapest roller-mop robot on this list. Its 270 mm SpiraFlow roller is wetted by 8 clean-water points and wiped by a built-in scraper as it works, so it does not push dirty water around a room. Roborock says mopping pressure reaches 15 N, up from 6 N on the original Qrevo Curv, and the roller lifts up to 15 mm under a Roller Shield on carpet. Suction is 20,000 Pa with anti-tangle side brushes and a DuoDivide main brush, and LiDAR plus structured light and an RGB camera handle mapping and avoidance. The dock washes the roller at 167°F and dries it at 131°F. Roborock is unusually open about noise, listing 56 to 57 dB for washing and 70 dB for under a minute while emptying. The cooler wash and 1-year warranty keep it just behind Dreame. We compared documented features and published prices.
