PROBLEM TO BE SOLVED: To provide a cleaning device for collecting dust by electrostatic adsorption.SOLUTION: A main body case includes: a static electricity generation means storage chamber having a wide suction port in the lower surface; and travel wheels to rotatably have contact with a cleaned surface. A cleaning device includes inside the main body case: a cylindrical rotation adsorption body rotatably stored in the static electricity generation means storage chamber so as to face the suction port by non-contact with the cleaned surface; a dust movement body where multiple small-diameter brush pieces stored in parallel to allow the outer surfaces to have contact with the rotation adsorption body are radially formed; a dust collection chamber having comb-shape dust removal body to be abutted to the dust movement body; and a transmission mechanism constituted by gears, etc. for transmitting the rotation of the travel wheels so as to allow the rotation adsorption body and the dust movement body to be rotated by respective predetermined rotation frequencies. The rotation adsorption body and the dust movement body are constituted by respective materials, i.e. the rotation adsorption body is constituted by a base material to be negatively charged in rotation contact and the dust movement body is by a base material to be positively charged in rotation contact.SELECTED DRAWING: Figure 3 |
