To solve the problem that a conventional squeegee is easily hooked by the unevenness of a floor surface so that smooth operation can not be done and therefore can hardly respond especially to a tiled floor surface with an uneven pattern or a floor surface covered with a carpet, and that operation efficiency is markedly reduced in a carpet with an uneven pattern.

The squeegee for sucking and removing a contaminated water after cleaning the floor surface with a suction device by moving on the floor surface has a suction port in communication with the suction device and sled-shaped sliding portions in front and rear sides of the suction port in the bottom part, a plurality of suction elements whose one end side is turnably attached to a squeegee body and whose suction port portion at the other end side is vertically movably supported and downwardly biased using an elastic body are arranged in parallel.
