Abstract
The present invention discloses a robot that moves on a surface. The robot includes a casing, a moving unit coupled to the casing, and a suction disk coupled to the casing. The casing, the suction disk and the surface are configured to form an airtight space. The robot further includes an air extraction module and a spray module. The air extraction module is disposed in the casing and is in communication with the airtight space, and the air extraction module is configured to generate a negative pressure in the airtight space. The spray module is coupled to the casing and configured to spray a liquid onto the surface.

A cleaning robot configured to move on an inclined or vertical surface, the cleaning robot comprising:
- a casing;
- a moving unit coupled to the casing;
- a suction disk coupled to the casing, wherein during a cleaning operation the suction disk is configured to contact the surface, and the casing, the suction disk and the surface are configured to form an airtight space for allowing the cleaning robot to move on the surface without falling off due to gravity;
- an air extraction module, disposed within the casing and in communication with the airtight space, configured to generate a negative pressure in the airtight space;
- and
- a spray module coupled to the casing, wherein the spray module comprises a water outlet provided on a side of the cleaning robot and configured to spray a liquid from the side of the cleaning robot onto the surface.
