Abstract
A squeegee apparatus for a vacuum cleaner system. The apparatus includes a main body portion having an integrally formed neck portion operable to releasably connect to a wand of the vacuum cleaner system. The main body portion forms a manifold and includes a lower end portion to which a squeegee member is releasably secured. The squeegee member includes a central portion having a pair of longitudinally parallel extending bumper portions, with the bumper portions each including saw tooth-shaped surfaces. The squeegee blade also depends downwardly from the central portion and outwardly of the bumper portions. The central portion also includes first and second pluralities of ports disposed on opposite sides of the squeegee blade, with one or the other of the pluralities of ports being alternately blocked off during use as the squeegee blade flexes into abutting contact with one or the other of the bumper portions while being moved back and forth over a work surface. The bumper portions also function to maintain the pluralities of ports at a predetermined distance from the work surface during use, thereby maximizing the consistency of the liquid pick-up operation of the apparatus.
