ABSTRACT:
A glass surface cleaning machine includes a supporting frame which has a fluid receiving chamber provided therein and includes a supporting arm frontwardly extended therefrom, a wiper blade transversely mounted on a front edge of the supporting arm of the supporting frame for wiping on a glass surface, and a vacuum device supported by the supporting frame. The vacuum device includes at least a fluid suction nozzle supported underneath the wiper blade and in communication with the fluid receiving chamber and an impeller to create a low pressure within the fluid receiving chamber with respect to the atmosphere pressure so as to create a sucking effect for removing fluid from the glass surface through the fluid suction nozzle and directing the fluid to deposit in the fluid receiving chamber.
