Floor cleaning device
First Claim
1. A wet extraction cleaning device comprising:
- a base assembly adapted to move on a surface to be cleaned, the base assembly comprising an inlet nozzle forming a fluid communication path between an inlet slit and a nozzle outlet, the inlet slit being located on the base assembly proximal to the surface to be cleaned;
an operation handle pivotally attached to base assembly, and having a pivot axis about which the operation handle pivots relative to the base assembly;
a supply tank adapted to hold cleaning fluid and having a supply tank outlet;
a recovery tank adapted to hold recovered fluid, and having a recovery tank inlet and a recovery tank outlet;
a fluid deposition assembly in selective fluid communication with the supply tank outlet and adapted to convey fluid from the supply tank to the surface to be cleaned;
a vacuum source having a vacuum source inlet;
a first external pocket;
a second external pocket; and
wherein the supply tank is adapted to be selectively received in the first pocket to place the supply tank in fluid communication with the fluid deposition assembly, and the recovery tank is adapted to be selectively received in the second pocket to place the recovery tank inlet in fluid communication with the nozzle outlet and the recovery tank outlet in fluid communication with the vacuum source inlet.

Abstract
A wet extraction floor cleaning device having a base assembly adapted for movement on a surface being cleaned, an operating handle pivotally attached to the base assembly, a supply tank having a supply tank outlet, and a recovery tank having a recovery tank inlet and a recovery tank outlet. The base assembly has an inlet nozzle that extends from an inlet slit proximal the surface being cleaned to a nozzle outlet. The device further includes a fluid deposition assembly that can be selectively placed in fluid communication with the supply tank outlet, a vacuum source, and first and second external pockets. The supply and recovery tanks are adapted to be selectively placed in the first and second external pockets, thereby placing the supply tank outlet in fluid communication with the fluid deposition system, the recovery tank inlet in fluid communication with the nozzle outlet, and the recovery tank outlet in fluid communication with the vacuum source inlet.
