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.

Abstract: An air-releasing valve for use in a suction apparatus and a suction robot having the air-releasing valve are provided. The air-releasing valve comprises an activation unit and an air-releasing valve retaining base (3). An air-releasing hole (11) in communication with a negative pressure chamber (18) of the suction apparatus is provided on the air-releasing valve retaining base (3). The activation unit is provided on the air-releasing valve retaining base (3) and is movable relative to the air-releasing valve retaining base (3) to open the air-releasing hole (11). A switch (4) is provided on the air-releasing valve retaining base (3). The activation unit opens the air-releasing hole (11) and triggers the switch (4) to shut off a vacuuming apparatus (14) of the suction apparatus simultaneously. The air-releasing valve is capable of rapidly releasing air from the suction apparatus and shutting off the vacuuming apparatus (14) in a timely manner.
