ABSTRACT:
A mechanical cleaner for carpets or floors comprising a main casing having driving wheels which protrude through an open bottom and are rotatable by movement of the cleaner. A rotatable brush, driven by the wheels, is adapted to brush dust from the carpet or floor into a dust box on the main casing. A vertically moveable means for releasably mounting the brush comprises a pair of swinging frames, one end of each of which is rotatably journaled on the casing at a point spaced apart from the other swinging frame. The brush is rotatably mounted between the ends of the frames opposite the location of the journals and are urged downwardly. There is an engaging means on the casing which will releasably engage the frames and limit their downward movement. As a result, releasing the engaging means permits the frames carrying the brush to rotate downwardly to allow the brush to be detached and replaced by a new brush.
