Abstract:
A suction apparatus, a glass-wiping device and a run control method thereof. The suction apparatus comprises a suction cup unit ( 1 ). The suction cup unit ( 1 ) comprises an inner suction cup ( 11 ) and an outer suction cup ( 12 ). The inner suction cup ( 11 ) is arranged on the inside of the outer suction cup ( 12 ). A chamber on the inside of the inner suction cup ( 11 ) forms an inner negative pressure chamber ( 13 ) via vacuum suction. A chamber between the inner and outer suction cups ( 11  and  12 ) forms an outer negative pressure chamber ( 14 ) via vacuum suction. The outer negative pressure chamber ( 14 ) is connected to a vacuum detection unit. The vacuum detection unit comprises a distensible piece ( 20 ) and a distension-sensing piece ( 21 ). The distensible piece ( 20 ) is sealedly connected onto an opening on the top end of the outer negative pressure chamber ( 14 ). The distensible piece ( 20 ) has arranged thereon the distension-sensing piece ( 21 ). The glass-wiping device is provided with the suction apparatus, when in cases of failure of the outer suction cup ( 12 ) in the suction apparatus and of failure of the outer negative pressure chamber ( 14 ), the glass-wiping device will take measures immediately to prevent an increased number of small protrusions from entering the inner suction cup ( 11 ), thus preventing the phenomenon of the glass-wiping device falling off a wall from occurrence.

Claim (Index 8):
A method for controlling a surface cleaning device comprising:\n activating, by a controller, one or more vacuum pumps to control a pressure within a suction assembly engaged with a surface to be cleaned, the suction assembly having\n a first suction cup forming an outer negative pressure chamber, and \n a second suction cup disposed within the first suction cup forming an inner negative pressure chamber within the outer negative pressure chamber; \n activating, by the controller, a drive assembly having a driver unit and a running unit, the drive assembly configured to move the device along the surface at a walking speed, v; sensing, at the controller, vacuum detection data related to a pressure within the suction assembly; detecting, at the controller, vacuum detection data below a stored threshold pressure; controlling, by the controller, the drive assembly based on the detecting.
