る。When the electric blower 12 is driven by operating the power setting switch, the dust collection chamber 11 has a negative pressure, and the hose 15, the extension pipe 17, the connection pipe 22, and the communication air passage 40 have a negative pressure. When the suction port body 20 is moved forward, the rotating portion 3 is moved by the brush 35B of the detection member 35 as shown in FIG.
5A rotates counterclockwise around the cylinder shaft portion 36, and the valve element 37 closes the upper opening 41A of the first guide air passage 41.

前進移動操作は軽いものとなる。Further, since the contact piece 50 comes into contact with the contact 51 due to the counterclockwise rotation of the rotating portion 35A of the detection member 35, the voltage input to the input port 55 of the controller 54 is Vc.
Becomes The controller 55 reads the voltage Vc input to the input port 55, determines that the suction port body 20 is moving forward, drives the motor 33 in the normal direction, and rotates the cleaning body 3.
0, 31 are rotated counterclockwise as shown in FIG.
That is, the rotary cleaning bodies 30, 31 are rotated in the forward direction with respect to the moving direction of the suction port body 20, and the forward movement operation of the suction port bodies 30, 31 becomes light.

る。Then, the dust scraped up by the rotary cleaning bodies 30, 31 is sucked from the suction opening 24A of the second suction chamber 24. That is, after the dust is picked up by the rotary cleaning bodies 30 and 31, it is sucked by the suction opening 24A of the second suction chamber 24, and the scratched dust is sucked by the suction opening 24A of the second suction chamber 24. The suction can be surely performed, and it is possible to prevent the scraped dust from being left.

The control device 55 reads the voltage (0 volt) input to the input port 55 and determines that the suction port body 20 is moved backward, and drives the motor 33 in the reverse direction to rotate the rotary cleaning body 30,
Rotate 31 counterclockwise. That is, the rotary cleaning body 30 is rotated in the forward direction with respect to the moving direction of the suction port body 20, and the backward movement operation of the suction port body 20 becomes light.

That is, after the dust is picked up by the rotary cleaning bodies 30, 31, it is sucked in by the suction opening 23A of the first suction chamber 23, and the scratched dust is sucked by the suction opening 23A of the first suction chamber 23. The suction can be surely performed, and it is possible to prevent the scraped dust from being left.
