A pump for removing fluid from a floor covering includes a piston chamber, a piston disposed within the piston chamber, a nozzle plate for pressing against the floor covering and having a plurality of nozzles extending therefrom, a reservoir for storing fluid removed from the floor covering, and a diverting valve having an interior. The diverting valve defines a first fluid flow path, a second fluid flow path, and a third fluid flow path. A method of removing fluid from a floor covering includes causing a piston to move in a first direction within a piston chamber, drawing fluid through a plurality of nozzles of a nozzle plate and into the piston chamber, causing the piston to move in a second direction within the piston chamber, and pushing fluid from the piston chamber and into a reservoir extending circumferentially around the piston chamber.

A compact machine for cleaning floors includes a solution tank and dispensing system for dispensing solution onto the surface to be cleaned, a deck assembly for guiding dirty solution to a recovery pickup point, a mechanically operated pump for collecting the dirty solution from the recovery pickup point, and a recovery tank for receiving the collected fluid.

This patent relates to devices that can be manipulated by a user to expel or draw in a material. In one example, a hand-operable vacuum device can include an interface portion configured to contact a material. The hand-operable vacuum device can also include a deformable portion that extends along an axis that passes through the interface portion and wherein the deformable portion includes at least one longitudinally-oriented resilient structure that extends generally parallel to the axis.
