Roomba S9+ vs Roborock Qrevo: S9+ wins on carpet corners, Qrevo wins on hard floors

Regarding the Roborock: The Roomba S9+’s D-shape digs into corners that round robots like the Qrevo miss, leaving carpets spotless without manual touch-up. The Qrevo outperforms on hard floors, but for wall-to-wall carpet, the S9+ cleans more thoroughly thanks to its flat front edge and powerful suction.
