The Shark PowerDetect ThermaCharged RV2920XE is the robot vacuum this comparison selects, as the better reviewed, more affordable model with a 2 year warranty and a 379ml onboard bin. The Roborock Saros 10 still leads on a 220 minute battery against 180, on Matter, Apple Home and SmartThings, and on 22000Pa of published suction. Shark does not publish a pascal figure, so suction is not a scored loss. Both mop, wash, dry, lift and self-empty. Choose the Shark when warranty, price and reviews lead, and the Roborock when the smart home and the longer run lead.

What owners say

Owners of both flagships talk about floors they stopped mopping and a map that usually behaves, then they hit different faults. Roborock Saros 10 owners single out hair from under furniture, a body low enough to slip under sofas, and a dock that refills water and detergent, and they complain about bag and pad costs, slow full-house mop runs, and weaker results on thicker carpet. Shark PowerDetect ThermaCharged RV2920XE owners, often pet homes and parents, single out hot mop washing and quiet mapping, and they complain about the robot missing the dock, false mop obstructions, and water dispensing that quit on some units within months.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
