The Roborock Qrevo QV 35A still has an argument: it typically costs less and edges out a slightly larger onboard dustbin than the Roborock Saros 20 Sonic. Both are self-emptying vacuum-and-mop combos with LiDAR navigation and a dock that washes and dries the mop pads automatically, and both support Alexa and Google Home. Buyers who want flagship-level suction, the longest runtime and the broadest smart-home support should choose the Roborock Saros 20 Sonic; anyone who wants the core Roborock experience for a typically lower price should pick the Roborock Qrevo QV 35A.
