Abstract

A bare floor cleaner with an upright assembly pivotally mounted to a base assembly, a steam generator, a fluid distributor which distributes steam onto the surface to be cleaned, and a mop cloth provided on the base assembly. The mop cloth is mounted to the base assembly by a mop cloth plate that is removable from the base assembly.

Claims

1. A bare floor cleaner comprising:

a base housing which is movable along a surface to be cleaned;

an upright housing pivotally mounted to the base housing;

a universal joint between the base housing and the upright housing;

a steam generator mounted in one of the base housing and the upright housing;

a mop cloth plate removably mounted to the base housing;

a mop cloth removably mounted to the mop cloth plate and positioned for contacting the surface to be cleaned; and

a fluid distributor mounted in the base housing and connected to the steam generator to distribute steam to the mop cloth;

a retention mechanism releasably retaining the mop cloth plate on the base housing, wherein the mop cloth is configured to be removably retained on the mop cloth plate so that the mop cloth plate and the mop cloth can be simultaneously removed from or mounted to the base housing as a unit, wherein the retention mechanism is a locking mechanism comprising;

a catch configured to engage the mop cloth plate for retaining the mop cloth plate on the base housing;

a release latch operably coupled with the catch for selectively releasing the catch from the mop cloth plate when the release latch is actuated, and

a detent mechanism for releasably retaining the catch in a released position when the mop cloth plate is removed from the base housing, and the detent mechanism further is adapted to reset the catch to releasably retain the mop cloth plate on the base housing when the mop cloth plate is replaced on the base housing.

2. The bare floor cleaner according to claim 1, wherein the release latch is configured to be operated by the foot of a user.

3. The bare floor cleaner according to claim 2 wherein the release latch is provided on the base housing.

4. The bare floor cleaning according to claim 1 wherein the detent mechanism further comprises an over-center spring that biases the catch to the released position.

5. The bare floor cleaning according to claim 4, wherein the locking mechanism further comprises an arm operably coupling the release latch with the catch, wherein the arm is biased by the over-center spring to move the catch to the released position.

6. The bare floor cleaner according to claim 1, wherein the base housing has an opening therein and the mop cloth plate is installed on the base housing through the opening, and wherein the detent mechanism comprises a lever which is positioned in the opening after the mop cloth plate is removed from the base housing and is moved from the opening when the mop cloth plate is replaced in the opening to reset the catch.

7. The bare floor cleaner according to claim 1 and further comprising a dirt receptacle positioned in the base housing, wherein the mop cloth plate comprises a portion of the dirt receptacle.

8. The bare floor cleaner according to claim 7, wherein the portion of the dirt receptacle comprises a flange on the dirt receptacle and the mop cloth is removably attached to the flange.

9. The bare floor cleaner according to claim 1, wherein the upright housing comprises a handle for maneuvering the base housing along the surface to be cleaned.

10. The bare floor cleaner according to claim 9 and further comprising a trigger on the handle operably connected to the fluid distributor for selectively distributing steam onto the surface to be cleaned.

11. The bare floor cleaner according to claim 1 and further comprising:

a sweeper mounted to the base housing and adapted to contact the surface to be cleaned to remove dust and dirt particles therefrom; and

a dirt receptacle positioned in the housing in a location to receive the dust and dirt particles swept from the surface to be cleaned by the sweeper.

12. The bare floor cleaner according to claim 11 and further comprising a motor mounted on the base housing and operably connected to the sweeper for rotationally driving the sweeper.

13. The bare floor cleaner according to claim 11, wherein the dirt receptacle is slidably received within the base housing and is installed into the base housing through an opening a lower surface of the base housing.

14. The bare floor cleaner according to claim 11, wherein the sweeper comprises one of:

a brush made of tufted bristles;

a brush made of blades or paddles; and

a brush made of a soft and compressible material.

15. The bare floor cleaner according to claim 1 and further comprising:

a tank mounted to one of the base housing and the upright housing, and adapted to hold a quantity of fluid; and

a fluid distribution system between the tank and the steam generator for distributing fluid from the tank to the steam generator.

16. The bare floor cleaner according to claim 1, wherein the fluid distributor is positioned above the mop cloth for distributing steam to the mop cloth.

17. A bare floor cleaner comprising:

a base housing which is movable along a surface to be cleaned;

an upright housing pivotally mounted to the base housing by a universal joint;

a fluid distribution system comprising;

a fluid distributor mounted in the base housing for distributing fluid to the surface to be cleaned;

a water tank mounted to the upright housing and adapted to hold a quantity of water;

a conduit between the water tank and the fluid distributor and extending through the universal joint to convey fluid from the water tank to the fluid distributor; and

a heating element in the conduit for heating the water from the water tank to steam, whereby the steam is distributed to the surface to be cleaned by the fluid distributor;

a mop cloth plate mounted to the base housing;

a mop cloth removably mounted to the mop cloth plate and positioned for contacting the surface to be cleaned; and

a foot operated release mechanism releasably mounting the mop cloth plate to the base housing, the release mechanism comprising;

a pivot member having a catch configured to engage the mop cloth plate for retaining the mop cloth plate on the base housing; and

a release latch configured to be operated by the foot of a user operably coupled with the pivot member for selectively releasing the catch from the mop cloth plate when the release latch is actuated;

wherein the mop cloth is configured to be removably retained on the mop cloth plate so that the mop cloth plate and the mop cloth can be simultaneously removed from or mounted to the base housing as a unit.

18. The bare floor cleaner according to claim 17 and further comprising a dirt receptacle positioned in the base housing, wherein the mop cloth plate comprises a portion of the dirt receptacle.

19. The bare floor cleaner according to claim 18, wherein the portion of the dirt receptacle comprises a flange on the dirt receptacle and the mop cloth is removably attached to the flange.

20. The bare floor cleaner according to claim 17 and further comprising a sweeper mounted to the base housing and adapted to contact the surface to be cleaned to remove dust and dirt particles therefrom.
