Abstract

A surface cleaning apparatus includes a housing, a fluid delivery system including a supply tank removably mounted on the housing and a fluid distributor, a fluid recovery system having a recovery tank removably mounted on the housing, an extraction nozzle, a motor/fan assembly, and a supply tank receiver provided on the housing for receiving the supply tank and comprising a void at least partially defining a seat for the supply tank.

First claim

What is claimed is:

1. A surface cleaning apparatus, comprising:
a housing including a partition having opposing sides;
a fluid delivery system comprising a supply tank removably mounted on the housing and a fluid distributor;
a fluid recovery system having a recovery tank removably mounted on the housing, an extraction nozzle, and a motor/fan assembly;
a recovery tank receiver provided on the housing for receiving the recovery tank and comprising a void at least partially defining a seat for the recovery tank;
a recovery tank latch provided on the recovery tank receiver and configured for securing the recovery tank to the recovery tank receiver;
a supply tank receiver provided on the housing for receiving the supply tank and comprising a void at least partially defining a seat for the supply tank, wherein the supply tank receiver and the recovery tank receiver are located on opposing sides of the partition; and
a supply tank latch provided on the supply tank receiver and configured for securing the supply tank to the supply tank receiver.

2. The surface cleaning apparatus of claim 1 wherein the supply tank latch further comprises a latch member selectively moveable between a retracted position and an extended position where the latch member extends into the void and a biasing member configured to bias the latch member into the extended position.

3. The surface cleaning apparatus of claim 2 wherein the seat comprises a platform and a first overhanging portion spaced above the platform and the supply tank latch is provided on an underside of the first overhanging portion.

4. The surface cleaning apparatus of claim 3 wherein the first overhanging portion includes a pocket therein and the supply tank latch is at least partially retained within the pocket.

5. The surface cleaning apparatus of claim 4 wherein the biasing member further comprises a coil spring retained between the latch member and a contoured portion of the pocket.

6. The surface cleaning apparatus of claim 3 wherein the supply tank further comprises a catch provided at an upper portion thereof and wherein the catch is configured to retain the latch member.

7. The surface cleaning apparatus of claim 6 wherein the catch comprises a recess defined by an upper wall of the supply tank that further receives at least a portion of the first overhanging portion within the recess.

8. The surface cleaning apparatus of claim 6 wherein the latch member further comprises an angled portion or a ramped portion configured for engaging the catch, via an interference fit, when the latch member is in the extended position.

9. The surface cleaning apparatus of claim 2 wherein the housing further comprises an upright handle assembly including the supply tank receiver and a cleaning head mounted to the upright handle assembly and adapted for movement across a surface to be cleaned.

10. The surface cleaning apparatus of claim 9 , further comprising a pivotable joint coupling the upright handle assembly to the cleaning head.

11. The surface cleaning apparatus of claim 9 wherein the supply tank further comprises a bottom wall at a bottom end and a side wall extending from the bottom wall toward a top end and wherein the side wall includes indentations configured to form a grip for a user.

12. The surface cleaning apparatus of claim 1 , wherein the seat for the recovery tank comprises a platform and a second overhanging portion spaced above the platform and the recovery tank latch is provided on an underside of the second overhanging portion.

13. The surface cleaning apparatus of claim 1 wherein the housing comprises a base, the partition extends upwardly from the base, and the seat of the supply tank receiver and the seat of the recovery tank receiver are defined by portions of the base.

14. The surface cleaning apparatus of claim 13 wherein the base has a lower surface adapted to rest on a surface to be cleaned.

15. The surface cleaning apparatus of claim 1 wherein the partition comprises a carry handle at an upper portion thereof which facilitates carrying the surface cleaning apparatus.

16. The surface cleaning apparatus of claim 1 wherein the surface cleaning apparatus is a portable extraction cleaner.
