The various components of the extraction cleaner can be arranged for a balanced weight in hand. The supply tank can be integrated with a fluid distributor in a removable, modular unit. ## Claims ### Claim 1 A handheld extraction cleaner, comprising: a body provided with a carry handle; a working air path through the body having a dirty air inlet, defined by a suction nozzle, and a clean air outlet; a suction source in fluid communication with the dirty air inlet; and a recovery tank selectively carried by the body, the recovery tank including a flapper valve thereon, the flapper valve configured to be pushed open by a portion of the body when the recovery tank is mounted to the body and the flapper valve configured to automatically close when the recovery tank is removed from the body. ### Claim 2 (depends on 1) The handheld extraction cleaner of claim 1 wherein the recovery tank comprises a hollow tank body with an inlet opening and the flapper valve seals the inlet opening when the recovery tank is removed from the body. ### Claim 3 (depends on 2) The handheld extraction cleaner of claim 2 wherein the hollow tank body further comprises an outlet opening selectively closeable via a cap. ### Claim 4 (depends on 2) The handheld extraction cleaner of claim 2 wherein the flapper valve includes an elastically deformable flap moveable between an opened position and a closed position. ### Claim 5 (depends on 2) The handheld extraction cleaner of claim 2, further comprising a separator fluidly coupled to the working air path, the separator having a debris outlet, and the separator adapted to transfer debris and liquid separated from the working air path into the recovery tank. ### Claim 6 (depends on 5) The handheld extraction cleaner of claim 5, further comprising a seal provided around the debris outlet and adapted to prevent fluid leaks between the debris outlet and the inlet opening. ### Claim 7 (depends on 5) The handheld extraction cleaner of claim 5, further comprising a valve actuator provided adjacent the debris outlet, the valve actuator adapted to automatically open the flapper valve when the recovery tank is mounted to the body. ### Claim 8 (depends on 7) The handheld extraction cleaner of claim 7 wherein the valve actuator comprises at least one rib. ### Claim 9 (depends on 8) The handheld extraction cleaner of claim 8 wherein the at least one rib comprises a pair of ribs projecting from a rear edge of the debris outlet. ### Claim 10 (depends on 2) The handheld extraction cleaner of claim 2, further comprising at least one rib adapted to push open the flapper valve when the recovery tank is mounted to the body. ### Claim 11 (depends on 1) The handheld extraction cleaner of claim 1 wherein the body further comprises a recovery tank receptacle formed on a portion of the body. ### Claim 12 (depends on 11) The handheld extraction cleaner of claim 11, further comprising a recovery tank latch provided on the body, the recovery tank latch adapted to secure the recovery tank within the recovery tank receptacle. ### Claim 13 (depends on 1) The handheld extraction cleaner of claim 1, further comprising a supply tank carried by the body, a fluid distributor fluidly coupled with the supply tank, and a receptacle for removably mounting the supply tank to the body, wherein the receptacle is provided forwardly of the carry handle. ### Claim 14 (depends on 13) The handheld extraction cleaner of claim 13, further comprising a tank cavity provided in the body below the carry handle, wherein a portion of the supply tank is insertable through the receptacle and into the tank cavity. ### Claim 15 (depends on 13) The handheld extraction cleaner of claim 13 wherein at least a portion of the supply tank extends under the carry handle. ### Claim 16 (depends on 13) The handheld extraction cleaner of claim 13 wherein the fluid distributor is positioned to deliver fluid directly to a surface to be cleaned, outwardly in front of the suction nozzle. ### Claim 17 (depends on 16) The handheld extraction cleaner of claim 16 wherein the fluid distributor comprises a spray tip provided on the front of the suction nozzle. ### Claim 18 (depends on 1) The handheld extraction cleaner of claim 1, further comprising an agitator provided on a bottom of the body, rearwardly of the suction nozzle and forwardly of the recovery tank. ### Claim 19 (depends on 1) The handheld extraction cleaner of claim 1, further comprising a battery pack carried by the body and electrically coupled with the suction source, wherein the battery pack is located at least one of: above the suction source or rearwardly of the carry handle. ### Claim 20 (depends on 1) The handheld extraction cleaner of claim 1, further comprising at least one of: a flat back end on a rearward end of the body configured to support the handheld extraction cleaner in a self-standing position on a surface; a motor housing substantially enclosing a motor of the suction source and at least one baffle integrally formed with the motor housing and configured to dampen motor noise; and a window cleaning attachment comprising a squeegee and a foam scrubber, wherein the window cleaning attachment is removably mounted on the body with the squeegee and the foam scrubber substantially below the suction nozzle.
