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.
