Abstract
A window-cleaning robot provided with a closed wiper (13), comprising a rotating base (10) and an outer frame (20); said rotating base (10) being rotatably disposed on the outer frame (20); the bottom of said outer frame (20) being provided with a cleaning unit (21); said rotating base (10) being provided with a travel unit (11) and a suction cup (12); the bottom surface of the rotating base (10) also being provided with a wiper (13); said wiper (13) being disposed on the bottom surface such that the wiper (13) surrounds the rotating base (10) in a closed shape; the travel unit (11) and/or the suction cup (12) being enclosed within said closed shape. The wiper (13) is entirely closed such that regardless of where the robot travels, 360° wiping can be accomplished, effectively preventing the travel unit (11) and the suction cup (12) from becoming wet, resulting in more effective wiping and effectively preventing slippage.
