Abstract

A portable surface cleaning apparatus for a floor surface includes a recovery tank and a supply tank separated by a partition, and further includes a carry handle defining a handle grip spaced above the supply and recovery tanks, wherein the handle grip does not intersect the supply tank or the recovery tank.

First claim

What is claimed is:

1. A portable surface cleaning apparatus for delivering a cleaning fluid to and extracting cleaning fluid and debris from a surface to be cleaned, the portable surface cleaning apparatus comprising:
a main housing assembly carrying a fluid delivery system for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system for removing the cleaning fluid and debris from the surface to be cleaned and storing the recovered cleaning fluid and debris, the main housing assembly comprising a base housing with an upwardly extending partition housing;
the fluid delivery system comprising a supply tank received on the main housing assembly and a pump assembly in fluid communication with the supply tank, wherein the base housing defines an internal pump chamber for receiving the pump assembly;
the fluid recovery system comprising:
a recovery tank received on the main housing assembly and separated from the supply tank by the partition housing;
an extraction nozzle; and
a motor/fan assembly in fluid communication with the extraction nozzle and the recovery tank to generate a working air flow from the extraction nozzle into the recovery tank, wherein the motor/fan assembly is provided within the partition housing;

a carry handle defining a handle grip spaced above the supply tank and the recovery tank, wherein the handle grip does not intersect the supply tank or the recovery tank; and
a pump-cooling air pathway fluidly connected with the fluid recovery system and comprising an inlet defined by an inlet opening provided in the base housing.

2. The portable surface cleaning apparatus of claim 1 wherein the carry handle is at an upper portion of the partition housing.

3. The portable surface cleaning apparatus of claim 1 wherein the base housing and the partition housing collectively define two opposing tank receivers respectively receiving the supply tank and the recovery tank.

4. The portable surface cleaning apparatus of claim 1 and further comprising a button provided on the main housing assembly, adjacent the carry handle, and operably coupled to at least one electrical component within the main housing assembly.

5. The portable surface cleaning apparatus of claim 4 and further comprising a resilient boot seal provided around the button and isolating the button and the at least one electrical component from moisture ingress.

6. The portable surface cleaning apparatus of claim 1 and further comprising a resilient seal provided on a portion of the carry handle.

7. The portable surface cleaning apparatus of claim 6 wherein the resilient seal comprises a boot seal provided around an inner portion of the carry handle.

8. The portable surface cleaning apparatus of claim 1 wherein the fluid recovery system further comprises an air/liquid separator provided within the recovery tank for separating liquid from air in the working air flow.

9. The portable surface cleaning apparatus of claim 8 , and further comprising a mechanical coupling removably coupling the air/liquid separator to the recovery tank, wherein the mechanical coupling can be operated to selectively detach the air/liquid separator from the recovery tank for removal of the air/liquid separator from the recovery tank.

10. The portable surface cleaning apparatus of claim 1 and further comprising a suction hose in fluid communication with the extraction nozzle and the recovery tank, wherein the base housing includes a skirt having a suction hose rest adapted to receive the suction hose when wrapped around the skirt for storage.

11. The portable surface cleaning apparatus of claim 1 and further comprising a tool retaining bracket extending from the partition housing and adapted to retain an accessory tool, wherein the tool retaining bracket is below the carry handle.

12. The portable surface cleaning apparatus of claim 11 and further comprising a cord wrap caddy provided on the partition housing, adjacent the tool retaining bracket, for storing a power cord which emerges from an interior of the partition housing through a cord aperture, wherein the cord wrap caddy is below the carry handle.

13. The portable surface cleaning apparatus of claim 1 and further comprising a hand-held accessory tool in fluid communication with the supply tank and the recovery tank, wherein the extraction nozzle and a fluid distributor for delivering the cleaning fluid from the supply tank to the surface are provided on the hand-held accessory tool.

14. The portable surface cleaning apparatus of claim 1 and further comprising:
a button provided on the partition housing, adjacent the carry handle, and operably coupled to at least one electrical component within the main housing assembly; and
a resilient boot seal provided around the button and isolating the button and the at least one electrical component from moisture ingress.

15. The portable surface cleaning apparatus of claim 14 wherein the at least one electrical component is at least one of the motor/fan assembly or the pump assembly.
