Abstract
A squeegee assembly includes a front blade, a rear blade, and a support for mounting the blades. The front blade includes an outer surface, an inner surface, and a floor engaging edge. The rear blade includes an outer surface, an inner surface facing the inner surface of the front blade, and a wiping edge. The support includes a vacuum source port and a suction port. The rear blade has a curvature between opposing first and second ends of the rear blade that defines at least one rearmost point. At least the suction port is offset from a line of the support that extends through the at least one rearmost point parallel to a forward direction of travel of the squeegee assembly.
