ABSTRACT:
A cylindrical brush is mounted in a housing of a carpet-sweeping device or the like for rotation about an axis extending transversely of the direction of movement of the device over the surface to be cleaned. Two dirt-collecting receptacles are located respectively at the front region of the housing and at the rear region of the housing as considered in the direction of movement of the receptacle over the surface being swept. The dirt-collecting receptacles are removably mounted on the housing, and arrested in their respective fully inserted positions. The dirt-collecting receptacle can be introduced into the housing from the side through one of the lateral portions, from the front, from the rear, from below or from above, depending on the particular construction of the housing. Various arrangements for arresting the dirt-collecting receptacle in its fully inserted position are disclosed. The dirt-collecting receptacle proper has an inlet opening bounded by the top and bottom walls, as well as the two lateral walls, of the dirt-collecting receptacle. A guide wall may be provided which extends upwardly from the bottom wall at an angle thereto away from the brush, and a closing wall may be hinged to the top wall of the dirt-collecting receptacle and be held in its open position when the dirt-collecting receptacle assumes its fully inserted position, while assuming its closed position during the removal of the dirt-collecting receptacle from the housing.
