Roller-mop robot with 10,000 Pa suction, a 50°C hot-air drying station, Matter support and an optional plumbed water station.
Verdict: One of the cheapest ways into a self-rinsing roller mop, with Matter for smart-home fans. Suction is modest next to flagships, and it only clears about 20 mm thresholds.
The SwitchBot S20 mops with a RevoRoll roller that rinses itself as it cleans (RinseSync), pressing down with 1 kg at 300 cycles per minute. It vacuums at 10,000 Pa with anti-tangle rubber brushes and dToF LiDAR navigation plus an AI camera for obstacles. The station empties into a 4 L dust bag (up to 90 days) and dries the mop with 50°C hot air. It has a 2.7 L clean and 2.5 L dirty water tank, and SwitchBot sells an optional Water Station for automatic refill and drainage. Matter support adds Apple Home, Alexa and Google Home control.
