1. A handheld extraction cleaner, comprising:
- a unitary body provided with a carry handle;
a working air path through the unitary body having a dirty air inlet and a clean air outlet;
a suction source in fluid communication with the dirty air inlet;
a recovery tank carried by the unitary body;
a modular fluid supply assembly comprising a supply tank and a fluid distributor integrated with the supply tank;
a flow control valve at least partially controlling a delivery of fluid to the fluid distributor and configured to open upon seating the modular fluid supply assembly on the unitary body; and
including at least one of;
a receiver provided on the unitary body which places the supply tank in fluid communication with the fluid distributor when the modular fluid supply assembly is installed on the unitary body;
a flapper valve on the recovery tank configured to be pushed open by a portion of the unitary body when the recovery tank is mounted to the unitary body and to automatically close when the recovery tank is removed from the unitary body;
a flat back end on a rearward end of the unitary body configured to support the handheld extraction cleaner in a self-standing position on a surface;
a motor housing substantially enclosing the suction source and at least one baffle integrally formed with the motor housing and configured to dampen motor noise;
ora window cleaning attachment comprising a squeegee and a foam scrubber, wherein the window cleaning attachment is removably mounted on the unitary body with the squeegee and the foam scrubber substantially below the dirty air inlet; and
wherein the modular fluid supply assembly is removable from the unitary body as a single module, such that the fluid distributor is removed simultaneously with the supply tank.
