2026 verdict
Heated mop care and a 2-year warranty flip the cheaper robot: the Shark PowerDetect ThermaCharged RV2920XE wins this robot vacuum comparison with a 379ml onboard bin against 330ml on the Roborock Qrevo Pro.
The Qrevo Pro is still the lower-priced LiDAR combo dock, with FlexiArm pads and Home Assistant already listed. Both last about 180 minutes, map with LiDAR, and wash and dry mops after self-emptying runs, so this is not a features-versus-none split. Choose the Shark PowerDetect ThermaCharged RV2920XE for 185F mop washing and the longer warranty; choose the Roborock Qrevo Pro when the lower price and FlexiArm mopping are the rows that matter.
