ABSTRACT:
A squeegee attachment for a wet/dry vacuum cleaner having an elongate cleaning head and a deformable blade inserted into the head such that the blade barely extends past a lower portion of the cleaning head which forms part of a suction part, the blade effectively blocking the part in its nondeformed position and opening the part in its deformed position so as to create a maximum amount of suction at the surface to be cleaned.
