It runs 290 minutes against 180 and lists 25000Pa suction, a 4L water tank and a Matter update on the way. The Shark PowerDetect ThermaCharged RV2920XE is the one to look at for its heated mop-pad washing, and it has the larger onboard dustbin, 379ml against 245ml, with owners describing wood and tile mopping as outstanding. Both map with LiDAR, avoid obstacles, wash, dry and lift their mop pads, empty themselves at the dock and work with Alexa, Google Home and Home Assistant, and both carry a 2-year warranty. The Shark sheet leaves suction, tank and dock bin sizes blank, so a like-for-like power comparison stops at the Roborock's numbers. Pick the Roborock Qrevo Curv 2 Pro for big or mixed-floor homes, the Shark for hot-water mopping.

What the differences mean

Battery life

290 minutes on the Roborock Qrevo Curv 2 Pro against 180 minutes on the Shark PowerDetect ThermaCharged RV2920XE. In a large home the Roborock is more likely to finish a vacuum-and-mop run without going back to charge, while Shark owners recommend separate vacuum and mop schedules.

Documented power figures

The Roborock Qrevo Curv 2 Pro lists 25000Pa of suction, a 4L clean-water tank and a 2.7L dock bin. The Shark PowerDetect ThermaCharged RV2920XE lists none of those, so you cannot compare raw cleaning power on paper, only owner reports.

Onboard dustbin

The Shark carries 379ml and the Roborock 245ml. A larger bin means fewer mid-clean trips to the dock in a home with heavy shedding, which is where the Shark has the small edge.

Mop washing

Both wash, dry and lift their mop pads. The Shark PowerDetect ThermaCharged RV2920XE is built around high-heat washing, and owners say that is what keeps the pad from smearing. The Roborock Qrevo Curv 2 Pro also washes with hot water.

Smart home reach

Both work with Alexa, Google Home and Home Assistant, and neither is a Thread device. The Roborock Qrevo Curv 2 Pro lists Apple Home, SmartThings and Matter as an upcoming update, while the Shark lists none of them.

What owners say

Owners of both robots describe a dock that does most of the upkeep, and both groups run them in homes with pets. Roborock Qrevo Curv 2 Pro owners single out fast setup and accurate maps, strong suction and hot-water mopping, a carpet-climbing chassis and a run quieter than they expected, and they note that the box has no floor cleaner and no spare bag, that some find everyday suction less striking than the headline figure and that Apple Home waits on a later update. Shark PowerDetect ThermaCharged RV2920XE owners single out mopping on wood and tile, quiet operation, accurate carpet and hardwood detection and whole-home coverage on one charge when only vacuuming, and they report failures to leave or return to the dock, a mop cycle that falsely reports an obstruction and water dispensing that stops on some units within months.
