Abstract

A cleaning system. The system has a floor cleaning device, disposable floor sheet removably attachable to the device pad, and a rotatable beater bar. The device has a single wheel, and moves on the target surface by rolling action of the wheel and gliding of the floor sheet. This arrangement, not having multiple wheels, provides enhanced maneuverability, and improves cleaning performance. The cleaning system may be used to clean hard surfaces, such as a floor.

First claim

What is claimed is:

1. A foot for a floor cleaning device and being able to receive a handle pivotally attached thereto, said foot being movable on a floor and comprising:
a housing having a front side, a rear side longitudinally opposed thereto, a top and a bottom opposed thereto and two opposed sides connecting said front side and said rear side,
a sole plate juxtaposed with the bottom of the housing and being able to removably receive a disposable floor sheet thereon,
at least one wheel disposed in said foot and rotating in response to movement of said foot on a floor,
an axially rotatable beater bar with at least one blade extending radially outwardly therefrom, said beater bar rotating in response to rotation of said at least one wheel; and
a dirt bin disposed in said housing and in communication with said beater bar to receive debris therefrom and being removable through the top of said housing, said dirt bin having an inclined ramp fixedly mounted thereto and juxtaposed with said beater bar.

2. A foot according to claim 1 further comprising a castor and/or roller ball juxtaposed with the bottom of said foot, said castor and/or roller ball rotatably contacting a floor when said foot is placed thereon.

3. A foot according to claim 1 wherein said beater bar and said at least one wheel are coaxial.

4. A foot according to claim 3 having a longitudinal centerline, said axis of said at least one wheel being perpendicular to said longitudinal centerline.

5. A foot according to claim 1 having a longitudinal centerline, said at least one wheel being disposed on said longitudinal centerline.

6. A device for cleaning a hard surface, said device comprising:
a foot, said foot being connectable to a handle, said foot being movable on a hard surface, said foot having a front, a rear longitudinally opposed thereto, and two opposed sides connecting said front and said rear, said foot comprising
a sole plate for removably attaching a disposable sheet thereto;
an axially rotatable beater bar disposed in front of said sole plate, said beater bar rotating in response to movement of said foot on said hard surface,
said foot further comprising a plurality of wheels, at least one of said wheels being operably connected to said beater bar to cause rotation thereof when at least one of said wheels rolls on a hard surface, said plurality of wheels having a width of less than 10 mm between centerlines of said wheels.

7. A device according to claim 6 wherein said at least one wheel being operably connected to said beater bar has a diameter ranging from 18 to 63 mm.

8. A device according to claim 7 wherein said beater bar is gear driven, so that said beater bar is driven faster than said at least one said wheel.

9. A device according to claim 8 wherein said foot has a housing with said beater bar therein, wherein said beater bar is gear driven to be rotationally driven faster than said at least one said wheel.

10. A device according to claim 7 wherein said at least one wheel is stepped.

11. A device according to claim 10 wherein said at least one wheel is rotatably disposed on an axle and said axle is removable from said device independent of said beater bar.

12. A device for cleaning a floor, said device comprising
a foot, said foot being movable on a floor, said foot having a front side, a rear side longitudinally opposed thereto, and two opposed sides connecting said front side and said rear side,
a sole plate for removably receiving a disposable floor sheet thereon,
at least one wheel disposed in said foot and rotating in response to movement of said foot on a floor,
two axially rotatable beater bars juxtaposed with the front side of said device and operably connected to said wheel, one said beater bar being disposed on each side of said wheel, whereby said beater bars rotate in response to rotation of said wheel on a floor, each said beater bar being removable from said foot independently of said other beater bar,
at least one castor and/or roller ball mounted on said sole plate for contact with a floor and
an elongate handle pivotally connected to said foot.

13. A device according to claim 12 having a housing to contain said beater bar and said at least one wheel therein, wherein said beater bar rotates about an elongate axle, said axle being removable from said housing in a direction parallel to said axle.

14. A device according to claim 12 wherein said at least one wheel is disposed symmetrically intermediate said beater bars.

15. A device according to claim 12 having a longitudinal centerline, wherein each said beater bar is sleeved over a respective axle and being removable therefrom in a direction parallel to said axle and outwardly from said longitudinal centerline.

16. A device according to claim 15 wherein said at least one wheel is mounted intermediate two trunnions, each said trunnion supporting one said axle.

17. A device according to claim 12 wherein said at least one wheel and said beater bars are juxtaposed with the front side of said device.

18. A device according to claim 17 wherein each of said at least one wheels has a width of less than 10 mm.

19. A device according to claim 12 wherein said foot further comprises a dirt bin accessible from the top of said device.

20. A device according to claim 19 further comprising a vacuum for depositing debris into said dirt bin.
