ABSTRACT:
A squeegee assembly (60) includes first and second protrusions (314) interconnected to a support (172) to which front and rear flexible blades (170a, 170b) are mounted. In preferred aspects, squeegee assembly (60) is of a curved design such that the flexible blades (170a, 170b) are spaced at the center of the support (172) where a suction tube (174) is provided and taper towards each other so that their ends are closely adjacent each other. The first and second protrusions (314) define upper and lower channel portions (324, 326) between the flexible blades (170a, 170b) so that appreciable reduction in the speed of air flow towards the suction tube (174) does not occur, which reduction may result in dropping of carried moisture.
