Abstract
A cylindrical brush is mounted in a housing of a carpet-sweeping device 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 a front region of the housing and at a rear region of the housing as considered along this direction. Each dirt-collecting receptacle has an opening bounded on all sides by a plurality of walls and each receptacle is mounted for pivoting movement on the housing between a filling position in which the respective opening is located in a path in which dirt from the surface being swept travels into the receptacle, and a discharging position in which the opening is located out of the path so as to permit discharging of any deposited dirt from the receptacle. Each receptacle is lockable in its filling position, and each receptacle has top, bottom and rear walls which overlie open top, bottom, and end regions of recesses provided in the housing when a respective receptacle is locked in its filling position. An inclined guide wall may be provided at the opening for guiding the dirt from the brush into the receptacle.
