Abstract

Mopsweeping apparatus is disclosed which has a housing adapted to move over a surface to be cleaned. A cooperating pair of rollers is carried by the housing and comprises a first roller having a dust gathering cloth wound thereon and a second roller on which the cloth is windable. A motor is provided to drive the rollers for winding the cloth from the first roller to the second roller, with the winding direction being in the same direction as the direction of movement over the surface. A pressing structure under which the cloth is retained is provided. The pressing structure comprising two rollers over which an endless flexible belt is carried to provide a horizontal contact surface with the surface to be cleaned.

Claims

1. Mopsweeping apparatus comprising a housing adapted to be moved over a surface to be cleaned, a cooperating roller pair, carried by said housing, and comprising a first roller and a second roller, a supply of a dust gathering cloth wound on said first roller, said cloth being windable from said first roller to said second roller, means for driving said cooperating roller pair for winding said cloth from said first roller to said second roller, the winding direction of said cloth being in the same direction as the movement of said apparatus over said surface to be cleaned, and a pressing means under which said cloth is retained during movement of said apparatus over a surface to be cleaned, said pressing means comprising two rollers over which an endless flexible belt is carried, said pressing means providing a horizontal contact surface with said surface to be cleaned.

2. Mopsweeping apparatus according to claim 1, wherein the cloth is wound at a velocity which is considerably lower than the moving velocity of the apparatus.

3. Mopsweeping apparatus according to claim 2, characterized in that the winding velocity is 2-15 m/hour at a moving velocity of about 3-4 km/hour.

4. Mopsweeping apparatus according to claim 1, wherein the belt consists of an inert, resilient plastic material which is porous and which can take up the unevennesses of the floor and which is further resistant to chemicals and oil.

5. Mopsweeping apparatus according to claim 1, wherein said cloth is impregnated with a dust binding agent.

6. Mopsweeping apparatus according to claim 1, wherein the cloth is moisture or water absorbent.

7. Mopsweeping apparatus according to claim 6, wherein the cloth is impregnated with a floor cleaning agent and/or a floor maintaining agent.

8. Mopsweeping apparatus according to claim 1, wherein said housing is manually driven.

9. Mopsweeping apparatus according to claim 1, further comprising a means located adjacent the front of said apparatus in close proximity to said surface to be cleaned, for retaining coarse dirt particles.
