PROBLEM TO BE SOLVED: To remove by exfoliating almost completely dust in a duct by a system wherein a robot which cleans by exfoliating dust or the like in the duct, and a hose of a dust collector are provided, and the robot is so constituted as to be advanced by blowing out air from the air hose backward. SOLUTION: Air 8 from an air compressor is sent in a dry air machine 11 via an air hole 20, and dry air generated herein is sent to duct cleaning robot bodies 23, 23' via air hoses 13, 15. Respective robots 23, 23' rotate a rotor 3 together with a brush 5 at a high speed with air discharged from a through-hole 7a. Further, reverse blowing out force is given to the rotor 3 with the air jetted from an air nozzle 7c to obtain driving force. Thereby, deposited dust in the duct is exfoliated. The exfoliated dust is sent backward in the duct with the air jetted from the air nozzle 7c, and recovered in a filter box of the dust collector through the hose of the dust collector connected to the duct. |
