PURPOSE: To surely collect the dust removed with a brush without splashing the dust in a duct by providing a truck with the brush rotating to peel the dust forward or backward and forming a suction passage for sucking the peeled and removed dust in the truck. CONSTITUTION: The cleaning robot is inserted into a duct and wheels are rotated by a drive motor 3 thereof to cause the self-traveling of the robot within the duct. During this self-traveling, the brush 7 at the front end of the truck 1 of the robot is rotated counterclockwise by a drive motor 9 and the dust in the duct is peeled by the brush 7 and is removed toward the rear of the brush 7. The dust removed backward in such a manner is sucked by a fan 14 along the suction passage 4 formed in the truck 1 and is collected through a flexible hose 13 into the dust collecting bag in a dust collecting box 11. |
