Abstract
A surface or floor cleaning machine including scrubbing means and a following squeegee assembly is provided. The squeegee assembly includes a squeegee located near the rear of the machine and an arm pivotally connecting the squeegee to a frame of the machine between the squeegee and the scrubbing means at the forward end of the machine. A spring connects the squeegee arm and the machine near the pivot point to urge the arm and the squeegee downwardly. The squeegee has spaced wheels which movably support the squeegee blades on the surface to be cleaned so that the blades are not the sole support of the squeegee on the surface. In this manner, the squeegee blades are maintained firmly against the surface, even in uneven areas, while the wheels minimize the drag of the squeegee on the surface.
