Abstract

PURPOSE:To surely scrape off dust on an irregular surface to be cleaned by providing a plurality of rows of brush hair of a brush member on an opening face of a suction port, and forming suction openings on both sides along the longitudinal direction of the rows of brush hair. CONSTITUTION:Suction openings 8, 8... are formed on both sides along the longitudinal direction of rows of brush hair 7a, 7a, 7b, 7b. Dust scraped by the rows of brush hair 7a to 7b is immediately sucked by the suction openings 8, 8... near thereto. Thus, even when the dust is relatively large or cotton dust, it is not entangled in the brush hairs but pressed by the rows of brush hair, so that the dust does not remain. Since a plurality of rows of brush hair are separated from one another on a rugged face to be cleaned over the opening face of a suction port 4, the plurality of rows of brush hair 7a to 7b repeatedly enter recessed parts of an irregular surface to be cleaned and scraping-off movements are repeated. Accordingly, the dust in the recessed parts is effectively scraped off and sucked from the suction openings 8, 8....
