Abstract
In the invention, a brush body 30 that is rotated and driven by a motor 32 is disposed in a suction unit 2, and dust is sucked from the suction unit 2 by a blower 4, while exhaust of the blower 4 is sent to the suction unit 2 side through an exhaust passage 27. While the exhaust of the blower 4 is blown to the motor 32 exhaust is blown to the floor for lifting the dust from the floor to enhance the dust collection efficiency, and moreover, if the output of the motor 32 for driving the brush 30 is increased, temperature rise of the motor 32 can be suppressed, and thus durability may be enhanced.
