<p>The cleaner has a base unit movable by a chassis on a surface to be cleaned. A motor blower (11) produces low pressure acting on the surface to be cleaned, where the blower is arranged in the base unit. A pivoted joint is arranged between an upper body and the base unit. The upper body and the base unit are pivotably supported together around a horizontal axis in a usage condition by the pivoted joint. An air hose (106) guided to a suction side of the blower is rotatably supported opposite to the blower. The air hose forms a pivotal point of the pivoted joint.</p> |
