ABSTRACT:
A surface cleaning machine is provided which employs a drum broom at a forward portion of the machine for sweeping the floor, a hopper in front of the drum broom to receive debris therefrom, a plurality of disc-type scrubbing brushes at an intermediate portion of the machine for scrubbing the floor, and a squeegee assembly therebehind. A solution or supply tank and a recovery tank are located in side-by-side relationship at a forward portion of the machine, the solution tank supplying clean solution for the disc brushes and the recovery tank receiving dirty solution gathered by the squeegee assembly. The squeegee assembly is connected to the machine by arms which also raise and lower the assembly, the arms being engaged by a mounting plate carrying the disc brushes so that both the squeegee assembly and the disc brushes can be raised and lowered by common mechanism. The squeegee assembly has front and rear squeegee blades which are attached to a supporting member by clamping bands at the rear of the rear squeegee blade, the bands clamping both blades in place relative to the supporting member. The clamping arrangement requires no special attaching provisions such as fasteners and holes in the blades. The bands are quickly releaseable so that the squeegee blades can be easily and quickly removed and replaced, when necessary.
