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