Narwal Flow
$999.99
Buy on Amazon USA
Price is the Shark Stratos NeverTouch RV2720ZE's only win here: it costs less, but the Narwal Flow takes this robot vacuum comparison on owner rating, nearly double the runtime, and far broader smart home support, since the Shark reaches only Google Home, Alexa and Home Assistant while the Narwal Flow is Matter certified and adds Apple Home and Samsung SmartThings too. Both wash and dry their own mop pads, empty themselves, use laser navigation with multi-room mapping and no-go zones, and clean carpet. If price is the deciding factor, the Shark Stratos NeverTouch RV2720ZE still delivers a full self-cleaning vacuum-and-mop routine; for the longer runtime and the wider ecosystem reach, the Narwal Flow is the stronger buy.
