Which robot vacuums wash their mops in hot water?
Wash water and drying, robot by robot.
The Roborock Saros 20 washes its mops in the hottest water we track, up to 212°F. Three more reach 176°F: the Saros 10R, the Saros 10 and the Dreame X50 Ultra. Next, at 167°F, come the ECOVACS DEEBOT X9 PRO OMNI, the ECOVACS DEEBOT X11 OmniCyclone and the Narwal Freo Z10 Turbo. Roborock lists no hot water for the QV 35A, and eufy rinses the Omni S1 Pro’s pads in ozonated tap water.
