ABSTRACT:
A floor polisher with a dust collecting device has a buffing pad which is rotated at a high speed by a motor, a circular cover member and a skirt for covering an upper surface of the buffing pad, and a dust collecting device for exerting a collecting function thereof on an internal space surrounded by the cover member and the skirt. The floor polisher is characterized in that the cover member and the skirt are partly extended on a tangential line to form a guide chamber for a dust-containing air current, that the guide chamber is provided at an inlet port thereof with a guide wall opposite inner wall surfaces of the cover member and the skirt extended on the tangential line and an inclined plate which is inclined toward a floor, and that the guide chamber is provided at the outer end thereof with an outlet port communicating with the dust collecting device.
