The Multifunctional Dock 4.0 provides 10-in-1 hands-free maintenance including 176°F hot water mop washing, 176°F dock self-cleaning, automatic mop removal, auto detergent dispensing, and warm air drying. AdaptiLift Chassis climbs thresholds up to 4cm and lifts the mop up to 22mm on carpet. Compatible with Alexa, Google Assistant, Apple HomeKit, and Matter.
