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.
