摘要： An apparatus for cleaning windows and wall surfaces of a building which includes a cleaning head unit having squeegee blades, cleaning fluid nozzles and brushes together with apparatus for producing a vacuum pickup between the squeegee blades. The head unit is adjustably slidable on the rail of a platform and further it is mounted for lateral sliding movement on rollers engaging rails carried by the platform. The cleaning head unit includes a linkage and which allows positioning of the unit upon the window and/or wall surfaces and withdrawl of the unit from the surfaces. The cleaning head unit also has spring members for absorbing the shock of movement over irregular configurations of window and wall surfaces which also maintains the squeegees and brush in pressure engagement with the window and wall surfaces. The cleaning head unit cleans as the same is lowered and raised with the platform.
