eufy C28 Robot Vacuum Cleaner and Mop Combo, 15,000 Pa, HydroJet Roller Mop

Instead of spinning pads, the eufy C28 mops with a 28 cm roller. Water feeds through 24 ports while it turns at 270 RPM, and a built-in scraper sends the dirt into a separate tank so the roller stays clean while it works. Suction for the vacuum side is rated at 15,000 Pa and goes up on its own when it reaches carpet. Long hair is the other thing it's built around. eufy says the DuoSpiral brush takes strands up to 30 cm (11.8 in) without wrapping, based on its own trials with human hair and Golden Retriever fur. The station empties dust into a 3 L bag, washes the mop, dries it with 50°C air and collects the dirty water, and eufy says that covers up to 75 days before you need to step in. It navigates with LiDAR and no camera, which eufy pitches as a privacy feature. The trade-off is that its obstacle avoidance is specified for objects of 3 x 3 x 3 cm and larger. Runtime is listed at 140 minutes and the listed weight is 24 lb.
