In a suction-type floor cleaning device, the suction ports (4,5) and their associated valves (22,23) are integrated with each other. The brushes (2,3) are mounted through tapered conical surfaces on connecting members (39,40) attached to the brush bearings for easy and quick. brush removal. Connections to and from the fresh water (21) and wash water (17) tanks are provided on the common lid (20) for said tanks, which is hollow and houses the various hoses (19). This makes the removal of tanks for cleaning etc. easy. Suction port (4,5) movement and valve switching is isolated from the operating handle (31) and is operated by a springloaded lever handle (9-16) which rests in the forward cleaning mode. Larger wheels (62)with their peripheries offset from the rearside of the device provide easy movement over stairs. Support wheels (63,58,46) on the parking leg (34), suction ports (4,5) and device sides take the weight off the brushes during parking, reduce wear on the suction port skirtings (7,8) and of the brushes (2,3) respectively. |
