PURPOSE: To enable a suction means to be miniaturized and large dust to be sucked by forming a small space through the process of making longitudinal first and second floor surface contact members in contact with a floor surface, so as to suck air from the lower both sideway part, in a dust collector to be placed on a car body provided with wheels and moved.
CONSTITUTION: A small space A faced to a plurality of suction ports 4 of a suction means is formed by making a first floor surface contact member 8 and a second floor surface contact member 9 in contact with a floor surface 7. Air is sucked from a lower both sideway part 10 of an outside air intake port 5 and a suction part main body 6 so as to suck dust on the floor surface 7 of the small space A. The second floor surface contact member 9 is separated from the floor surface 7 with the movement of the car body 3 in the travel direction of the car body 3, so as to take dust into the small space A. After that, dust taken in by making the second floor surface contact member 9 in contact with the floor surface 7 is sucked by the suction means. Since the small clearance A has the large breadth and the cleaning area is increased with the movement of the car body 3, the wide place can be cleaned for a short period.
