发明名称 CARPET CLEANING DEVICE
摘要 The device is of the known type comprising a brush (32) which rotates and orbits about an eccentric axis to scrub powder distributed on the carpet. In order to prevent the tendency of the brush to redistribute the powder and create a streaked appearance, at least one pressing element (33, 37a or 37b) projects from the periphery of the brush. At this element sweeps across the carpet, it presses the powder into the carpet before the powder is scrubbed into the carpet by the main part of the brush.
