PROBLEM TO BE SOLVED: To provide a floor polishing device which allows slight dust scattered on the floor or dust generating in a polishing process to be sucked and the polished condition (accuracy) of the floor to be enhanced. SOLUTION: The floor polishing device P1 is provided with a polishing brush 2 on the outer rotor R of an outer rotor motor M. A hollow casing 1 of a hollow pipe shape is placed vertically at the center of the motor M, a stator S is fixed outside the hollow casing 1, and the outer rotor R is mounted outside the stator S rotatably through bearings 9. The polishing brush 2 whose center section only corresponding to the outer diameter of the hollow casing 1 is scooped out, is integrated with the outer rotor R as a body being placed horizontally at the bottom of the hollow casing 1, and a suction hose 4 is connected with the hollow casing 1 at the top. |
