Roborock Qrevo S5V

What testers say about the Roborock Qrevo S5V

The Roborock Qrevo S5V is a mid-range robot with two spinning mop pads of which one extends, a split anti-tangle main brush, an extending side brush and obstacle recognition with 3D structured light. The station empties the bin into a 2.7-liter bag, washes the pads and dries them with warm air. Vacuum Wars tested it and calls it a great-value robot, provided you find it discounted.

The surprise was carpet: 92 percent of the embedded sand came out, the fourth-best score among more than 150 robots tested, and pressed-in pet hair was picked up at 92 percent. Nothing was wrapped around the brush after the long-hair test. Mopping was good too: dried stains scored 120 points against a 93 average, and the overall mopping score came in well above average. The pads lift 0.4 inches on carpet, so vacuuming and mopping fit in one run.

The criticism: the station washes the pads in cold water where rivals increasingly use hot water, and the robot leaves about a quarter more water on the floor than average, which can cause streaks. The lidar sits in a fixed turret, thresholds stop at 0.8 inches and there is no water-line hookup. For homes with mostly carpet and pet hair that want a self-emptying station with mopping without flagship money, it is one of Roborock's strongest bargains.
