It moves 20,000 Pa, runs 242 minutes against 180 on the Shark PowerDetect ThermaCharged RV2920XE, and its dock washes and dries the roller automatically. The Shark PowerDetect ThermaCharged RV2920XE answers with mop-pad washing at 185 F that owners rate highly, a two-year warranty against one, and a larger 379 ml onboard bin, but it publishes no suction rating and carries no Matter support. The Roborock is also the lower-priced of the two, while the Shark has owner reports of docking and water-dispensing faults. Pick the Roborock Qrevo Curv 2 Flow for value and a roller mop, and the Shark PowerDetect ThermaCharged RV2920XE if heated pad washing and the longer warranty appeal.

What the differences mean

Mop type

The Roborock Qrevo Curv 2 Flow rinses its roller continuously with clean water so it never drags a dirty pad, while the Shark PowerDetect ThermaCharged RV2920XE uses mop pads washed at 185 F at the base. The roller scrubs better mid-run; the heated pad wash is the newer trick.

Runtime

The Roborock Qrevo Curv 2 Flow runs 242 minutes against 180 on the Shark PowerDetect ThermaCharged RV2920XE, a clear edge for a larger single-floor home.

Warranty

The Shark PowerDetect ThermaCharged RV2920XE is covered for two years and the Roborock Qrevo Curv 2 Flow for one, which matters given the docking and water-dispensing faults owners report on the Shark.

Smart home reach

The Roborock Qrevo Curv 2 Flow adds Matter through an announced over-the-air update, which brings Apple Home and SmartThings. The Shark PowerDetect ThermaCharged RV2920XE supports Alexa, Google Home and Home Assistant only.

Onboard bin

The Shark PowerDetect ThermaCharged RV2920XE carries a larger onboard bin, 379 ml against 325 ml on the Roborock Qrevo Curv 2 Flow, a small edge in how much it holds between dock visits.

What owners say

Owners of both robots rate the self-cleaning dock as the reason to buy, but they diverge on how reliable it is. Roborock Qrevo Curv 2 Flow owners describe running it daily for weeks without rescuing it, praise the roller mop that rinses as it works, and note it does not hug baseboards or reach under low cabinet kicks, with a minority reporting streaking on hardwood. Shark PowerDetect ThermaCharged RV2920XE owners, many with pets or a crawling baby, call it their best purchase and praise quiet operation, accurate mapping and whole-home coverage on one charge, yet report frequent failures to leave or return to the dock, a mop self-clean that falsely flags obstructions, and on some units water dispensing stopping 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.
