Abstract

A self-propelled walk behind floor cleaning apparatus includes a frame. A plurality of floor engaging wheels support the frame above a floor and a brush assembly fixed to the frame agitates a fluid on the floor. A floating tank is supported by the frame.

Claims

1. A self-propelled walk behind floor cleaning apparatus comprising:

a frame;

a plurality of floor engaging wheels supporting said frame above a floor;

a brush assembly fixed to said frame and agitating a fluid on the floor; and

a floating tank supported by said frame.

2. The floor cleaning apparatus as in claim 1, in which one of said tank and said frame includes a peg receptacle receiving a peg extending from the other of said tank and said frame, said peg receptacle having a length and being open along at least a portion of said length allowing said tank to float relative to said frame.

3. The floor cleaning apparatus as in claim 2, in which said tank includes a peg receptacle formed therein, and said peg receptacle opens downwardly.

4. The floor cleaning apparatus as in claim 1, in which said tank is pivotally supported on said frame.

5. The floor cleaning apparatus as in claim 4, in which a detachable restrainer restricts pivotal movement of said tank.

6. The floor cleaning apparatus as in claim 1, including a resilient latch urging said tank toward said frame.

7. The floor cleaning apparatus as in claim 1, in which said tank is partitioned into at least two volumes, one of said volumes holding unused cleaning solution and the other of said volumes holding recovered cleaning solution.

8. The floor cleaning apparatus as in claim 1, including a squeegee assembly fixed to a rear end of said frame, said squeegee assembly recovering solution from said tank.

9. The floor cleaning apparatus as in claim 1, in which said brush assembly includes at least one motor driven brush.

10. The floor cleaning apparatus as in claim 1, including handlebar fixed relative to said tank for grasping by a user walking behind and operating said apparatus.

11. A self-propelled walk behind floor cleaning apparatus comprising:

a frame having a rear end and a front end;

a plurality of floor engaging wheels supporting said frame above a floor;

a floating tank supported by said frame;

a fluid dispenser in fluid communication with said tank and dispensing a fluid from said tank onto a floor;

a brush assembly fixed to said frame rearwardly of said fluid dispenser and agitating the fluid on the floor; and

a squeegee assembly fixed to a said frame rearwardly of said brush assembly and recovering the fluid from the floor.

12. The floor cleaning apparatus as in claim 11 in which one of said tank and said frame includes a peg receptacle receiving a peg extending from the other of said tank and said frame, said peg receptacle having a length and being open along at least a portion of said length allowing said tank to float relative to said frame.

13. The floor cleaning apparatus as in claim 12, in which tank includes a peg receptacle formed therein, and said peg receptacle opens downwardly.

14. The floor cleaning apparatus as in claim 11, in which said tank is pivotally supported on said frame.

15. The floor cleaning apparatus as in claim 14, in which a detachable restrainer restricts pivotal movement of said tank.

16. The floor cleaning apparatus as in claim 11, including a resilient latch urging said tank toward said frame.

17. The floor cleaning apparatus as in claim 11, in which said tank is partitioned into at least two volumes one of said volumes holding unused cleaning solution and the other of said volumes holding recovered cleaning solution.

18. The floor cleaning apparatus as in claim 11, including handlebar fixed relative to said tank for grasping by a user walking behind and operating said apparatus.
