PURPOSE:To shorten cleaning work time by a method wherein an air blower and a dust collector are connected to both ends of ducts and wire ropes are attached to both sides of the front and rear of cleaning robots and these wire ropes are alternately wound up by respective winches placed at both ends of the ducts. CONSTITUTION:When respective winches 17, 18 are rotated as they are wound up and drawn out in exerting the air blast action of an air blower 4 and the suction action of a dust collector 5 on respective ducts 1A-1D, respective cleaning robots RA, RB are pulled up by the wire ropes and advance or rise up in the ducts 1A-1D with the rotation of brushes 9 and nylon strings 12. Dust DS sticking to and deposited on the inner wall is exfoliated by brushing and tapping. Thus, the exfoliated dust DS is subjected to the air blast action and sent out outside the ducts 1A-1D and collected in the collector 5 through respective suction hoses 5a. In this case one span of work can be lengthened and work time can be shortened. |
