Xiaomi Robot Vacuum X20 Max

The Robot Vacuum X20 Max vacuums and mops, with a dock that empties the dust on its own (rated by the manufacturer for up to 75 days) and washes the pads with water heated to about 55°C, then dries them with warm air in about 3 hours. The 4-litre water tank cuts down on frequent refills. An extending arm reaches the mop pad out toward walls and furniture legs, so edges get cleaned without a second manual pass; an ultrasonic sensor lifts the pads by 10 mm when it recognises a rug, and the same area can get a suction boost. At the front, a wide-angle structured-light sensor spots low obstacles, even in the dark, and a drop sensor turns the robot away from stairs.

The main brush cuts hair and fur collected during cleaning, to cut down on manual maintenance. The robot connects only to 2.4 GHz Wi-Fi. The official page does not specify whether Alexa and Google Assistant voice commands go through a separate device or a microphone on board the robot, nor whether the dock doses detergent on its own: the wash water is not described as mixed with any specific product. It suits someone who wants to minimise manual work on dust and pads, in a large home with several rugs.
