Abstract

A floor cleaning machine including a support frame with a handle attached to the upper end of the support frame for guiding the machine along the floor and a wheel assembly attached to the lower end. A plurality of disc-shaped floor cleaning pads disposed and held adjacent one another such that a floor pad cylinder having a horizontally-disposed longitudinal axis is formed are attached to the lower end of the frame. A motor supported by the frame rotates the floor pads about the axis on the floor in a vertical cleaning motion. A spraying system sprays cleaning fluid downward towards the floor and forward of the rotating cleaning pads. The dirtied cleaning fluid is then sucked up through a nozzle positioned behind the floor pad cylinder to a vacuum and holding tank assembly mounted on the frame.

Claims

1. A floor cleaning machine comprising:

a frame having a frame lower end and a frame upper end,

a handle attached to said frame upper end,

a wheel assembly attached to said frame for supporting, at least in part, said frame on a floor,

a plurality of disc-shaped floor cleaning pads, each having an outer edge adapted to clean the floor,

a holding means for holding said floor cleaning pads longitudinally adjacent one another such that a floor pad cylinder having a longitudinal axis is formed and such that said longitudinal axis is horizontally disposed,

said outer edges together forming the circumferential floor cleaning surface of said floor pad cylinder,

a motor supported by said frame for rotating said floor cleaning pads about said horizontal longitudinal axis,

said holding means holding said floor cleaning pads so that said outer edges, when said motor rotates said floor cleaning pads, engage the floor in a vertical cleaning motion,

a spraying means supported by said frame for spraying cleaning fluid towards the floor and generally forward of said floor cleaning pads,

a fluid pick-up means supported by said frame for recovering cleaning fluid from the floor after said floor cleaning pads have been rotated on the floor by said motor, and

said fluid pick-up means including a wiping member engageable with the floor, a holding tank supported by said frame for holding the excess fluid recovered from the floor, and a suction means generally adjacent to said wiping member for sucking excess fluid to said holding tank.

2. The floor cleaning machine of claim 1 including,

a cleaning fluid storage container supported by said frame for supplying fluid to said spraying means.

3. The floor cleaning machine of claim 1 including,

said wiping member comprising a squeegee positioned to be in contact with the floor.

4. The floor cleaning machine of claim 1 including,

said frame including spaced first and second frame members extending from said handle downward to said lower frame end, and

said motor and said holding tank being positioned between said first and second frame members.

5. The floor cleaning machine of claim 4 including,

said holding tank being positioned above said motor.

6. The floor cleaning machine of claim 1 including,

said cleaning pads having a horizontal pad assembly drive axis,

said motor having a horizontally extending motor drive shaft parallel to said pad assembly drive axis, and

a drive belt directly and drivingly connecting said motor drive shaft to said pad assembly drive shaft.

7. The floor cleaning machine of claim 1 including,

an arcuate shield positioned directly above and over the upper half of said cleaning pads, and

said spraying means being attached to said shield.

8. The floor cleaning machine of claim 1 including,

each said cleaning pad being made from fibers embedded in a resin.

9. The floor cleaning machine of claim 1 including,

said holding means including a pair of opposed metal discs positioned at the outer ends of said cylinder and having prongs projecting into the outermost said cleaning pads.

10. The floor cleaning machine of claim 1 including,

said motor being an electric motor operating at 3000 RPM.

11. The floor cleaning machine of claim 1 including,

said cleaning fluid comprising a fluid wax and a floor wax stripper fluid mixture.

12. The floor cleaning machine of claim 1 including,

said horizontal axis being spaced forward of said frame lower end.

13. The floor cleaning machine of claim 1 including,

said wheel assembly being attached to said frame behind the attachment point of said mounting means to said frame lower end.

14. The floor cleaning machine of claim 1 including,

said disc-shaped floor cleaning pads being formed of a non-woven abrasive material.

15. The floor cleaning machine of claim 1 including,

said suction means including a nozzle having an elongated horizontal opening positioned behind and parallel to said floor pads and hosing connecting said nozzle and said holding tank.

16. The floor cleaning machine of claim 1 including,

said disc-shaped floor cleaning pads being formed from randomly-distributed, air-layered fibers in a binder.

17. The floor cleaning machine of claim 1 including,

said disc-shaped pads being one-half to one inch thick and 12-14 inches in diameter, and

said holding means holding between five and nine said disc-shaped floor cleaning pads in adjacent relation.

18. The floor cleaning machine of claim 1 including,

said holding means including said disc-shaped floor cleaning pads being formed of a sticky material that causes the surfaces of adjacent disc-shaped floor pads to adhere to each other.

19. The floor cleaning machine of claim 1 including,

said holding means including a pair of horizontally opposed discs positioned at opposite ends of said floor pad cylinder and having prongs projecting horizontally inwardly into the end of said floor pads.

20. The floor cleaning machine of claim 1 including,

said floor pad cylinder having a longitudinal axis greater than its radius.
