- Which is better for carpet?
- The Qrevo Curv. Its 10,000 Pa suction is the stronger carpet figure here, and its mop pads lift so rugs stay dry. The Shark is built more around hard-floor mopping.
- Which mops better?
- The Shark PowerDetect UV Reveal. Its Hypersonic scrubbing claims 7x the scrubbing power of the Shark RV2820ZE, and its dock washes and heat-sanitizes the pad. The Qrevo Curv scrubs with rotating pads but does not state pad washing.
- Is the Shark worth the extra $77?
- Yes if you want UV stain detection, HEPA filtration and a dock that cleans and sanitizes the mop pad. No if carpet suction and a smaller dock matter more, since the Qrevo Curv wins both.
- Which avoids obstacles better?
- The Qrevo Curv, on paper. ZDNET and reviewers flag the Shark's avoidance as so-so against small items. The Shark's NeuraNav still handles dog toys and furniture well.
- Which lasts longer between charges?
- The Qrevo Curv lists a 5,200 mAh battery and up to 120 minutes of runtime. Shark does not publish a runtime figure for this model, so the Roborock is the only one you can plan around.
- Do both work with Alexa?
- Yes. Both list Amazon Alexa support and app control. The Qrevo Curv adds LiDAR mapping, and the Shark adds room-by-room targeting through its app.
