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.

1. An apparatus for cleaning a surface comprising: a collection tank having a first chamber and a second chamber, said first chamber and said second chamber having a top end and a bottom end; at least one first check valves connecting said first chamber and said second chamber such that a first fluid flows between said second chamber and said first chamber; at least one second check valves located at said top end of said first chamber such that a second fluid flows between inside of said first chamber and outside of said first chamber; and a piston chamber within said first chamber, said piston chamber having a piston located within, a rod coupled at a first end to said piston and at a second end to a pump handle located outside of said first chamber, said piston being movable in a first direction and a second direction within said piston chamber by actuation of said pump handle. 2. The apparatus of claim 1, wherein moving said piston in said first direction creates a vacuum in said first chamber thus closing said second check valves and opening said first check valves thereby causing said first fluid to flow from said second chamber to said first chamber.3. The apparatus of claim 1, wherein moving said piston in said second direction causes partial evacuation of said second fluid from said first chamber to said outside of said first chamber by opening said second check valves and closing said first check valves.4. The apparatus of claim 1, wherein said second chamber has at least one suction hole at said bottom end of said second chamber for, obtaining said first fluid.5. The apparatus of claim 4, further comprising: a suction finger coupled to each of said at least one suction hole, wherein said suction finger extends said suction hole to outside of said second chamber. 6. The apparatus of claim 5, wherein moving said piston in said first direction causes said suction fingers to be in substantial contact with any of said first fluid residing outside of said second chamber thereby causing said first fluid to flow through said suction fingers and through said second chamber to said first chamber.7. The apparatus of claim 5, further comprising: a plurality of bristle brush materials at said bottom end of said second chamber. 8. The apparatus of claim 1, further comprising: a fluid sprayer coupled to said collection tank, said fluid sprayer having a refillable reservoir. 9. The apparatus of claim 1, wherein said collection tank further comprises a drainage port for cleaning said collection tank.10. The apparatus of claim 1, wherein said first fluid flows in one direction from said second chamber to said first chamber.11. The apparatus of claim 1, wherein said second fluid flows in one direction from inside of said first chamber to outside of said first chamber.12. An apparatus for cleaning a surface comprising: a collection tank having a first chamber and a second chamber, said first chamber and said second chamber having a top end and a bottom end; at least one first check valves connecting said first chamber and said second chamber at said bottom of said first chamber and said top of said second chamber; at least one second check valves located at said top end of said first chamber such that a second fluid flows between inside of said first chamber and outside of said first chamber; and a piston chamber within said first chamber, said piston chamber comprising a piston and a and a rod coupled at a first end to said piston and at a second end to a pump located outside said first chamber, said rod having a hollow opening from outside said first chamber into said piston chamber thereby maintaining pressure of said outside of said first chamber within said piston chamber, said piston being movable in a first direction and a second direction within said piston chamber by actuation of said pump, wherein vacuum is created when said piston is moved in said first direction causing said first fluid to flow b etween said second chamber and said first chamber, and said second fluid flows between said first chamber and said outside of said first chamber when said piston is moved in said second direction. 13. An apparatus for cleaning a surface comprising: a collection tank having a first chamber and a second chamber, said first chamber and said second chamber having a top end and a bottom end; at least one first check valves connecting said first chamber and said second chamber such that a first fluid flows in one direction from said second chamber to said first chamber; at least one second check valves located at said top end of said first chamber such that a second fluid flows in one direction from inside of said first chamber to outside of said first chamber; and a cylindrical piston chamber within said first chamber, said piston chamber having a piston located within and a rod coupled at a first end to said piston and at a second end to a pump located outside said top end of said first chamber, said rod having a hollow opening from outside said first chamber into said piston chamber thereby maintaining pressure of said outside of said first chamber within said piston chamber, said piston being movable in a first direction and a second direction within said piston chamber by actuation of said pump, wherein vacuum is created when said piston is moved in said first direction causing said first fluid to flow from said second chamber tosaid first chamber, and wherein said second fluid flows from said first chamber to said outside of said first chamber when said piston is moved in said second direction. 14. An apparatus for cleaning a surface comprising: a collection tank having a top end and a bottom end; at least one first check valves located at said bottom end of said collection tank, said first check valves capable of passing a first fluid, said first check valves connecting inside of said collection tank at said bottom end through a first set of suction openings to outside of said collection tank; at least one second check valves located at said top end of said collection tank, said second check valves capable of passing a second fluid between inside of said collection tank and outside of said collection tank; and a piston chamber within said collection tank, said piston chamber comprising a piston located inside of said piston chamber and a rod coupled at a first end to said piston and at a second end to a pump located outside of said collection tank, said piston being movable in a first direction and a second direction within said piston chamber by actuation of said pump. 15. The apparatus of claim 14, wherein moving said piston in said first direction creates a vacuum in said collection tank thus closing said second check valves and opening said first check valves thereby causing said first fluid to flow from said outside of said collection tank to said inside of said collection valve.16. The apparatus of claim 14, wherein moving said piston in said second direction causes partial evacuation of said second fluid from said collection tank to said outside of said collection by opening said second check valves and closing said first check valves.17.
