Abstract
An apparatus for efficiently cleaning stains and extracting cleaning fluid from surfaces such as carpets and upholstery without requiring electrical power is presented. The invention eliminates the inconvenience of retrieving, filling with cleaning fluid, and plugging a deep cleaner into an electrical outlet in order to remove a small spot from a carpet. In addition to the scrubbing and fluid extracting capabilities, embodiments of the invention include a sprayer for applying cleaning fluid to stains. The sprayer may receive fluid from an attached refillable reservoir of cleaning solution, for example. During scrubbing, the top of a pump actuator provides resting place for the heel of a user's palm. The pump actuator may be locked down when scrubbing and unlocked for pumping to suck up fluid. A piston in a chamber provides the suction force for pulling fluid up through tubules, which may be interspersed between bristle tufts, past check valves and into a waste reservoir. A downward force on the piston provides the suction thereby assuring that the tubules are in contact with the surface during suction. The waste reservoir may be dumped via a plug in the waste reservoir.
