Abstract

A surface cleaning apparatus having comprises a surface cleaning head having a dirty air inlet; a longitudinally extending upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising first and second longitudinally spaced apart portable surface cleaning unit mounting members; a portable surface cleaning unit removably mounted to the upper portion and comprising an air treatment member and a suction motor; above floor cleaning wand removably mounted in the upper portion and removable when the portable surface cleaning unit is mounted to the upper portion; and, a flexible air flow conduit forming at least part of an air flow path from the above floor cleaning wand to the surface cleaning unit.

Claims

1. A surface cleaning apparatus comprising:

(a) a surface cleaning head having a dirty air inlet;

(b) a longitudinally extending upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position;

(c) a portable surface cleaning unit removably mounted to the upper portion and comprising an air treatment member and a suction motor;

(d) an above floor cleaning wand removably mounted to the upper portion and all of the above floor cleaning wand is removable when the portable surface cleaning unit is mounted to the upper portion wherein, when the portable surface cleaning unit is mounted to the upper portion and the above floor cleaning wand is mounted to the upper portion, an upright assembly is provided that comprises first and second longitudinally spaced apart portable surface cleaning unit mounting members; and

,

(e) a flexible air flow conduit forming at least part of an air flow path from the above floor cleaning wand to the portable surface cleaning unit.

2. The surface cleaning apparatus of claim 1 wherein the first portable surface cleaning unit mounting member comprises a pair of laterally extending portions.

3. The surface cleaning apparatus of claim 1 wherein the second portable surface cleaning unit mounting member provides a support on which the portable surface cleaning unit seats when mounted to the upper portion.

4. The surface cleaning apparatus of claim 1 wherein the upper portion comprises a portion of an air flow path from the dirty air inlet to the above floor cleaning wand.

5. The surface cleaning apparatus of claim 1 wherein, the surface cleaning head comprises an air flow path from the dirty air inlet to a cleaning head outlet and when the above floor cleaning wand is mounted to the upper portion, an inlet end of the above floor cleaning wand faces the cleaning head outlet.

6. The surface cleaning apparatus of claim 5 wherein the air flow path from the dirty air inlet to the cleaning head outlet comprises a flexible hose.

7. The surface cleaning apparatus of claim 1 further comprising an accessory cleaning tool connectable to the upstream end of the above floor cleaning wand when all of the above floor cleaning wand has been removed from the portable surface cleaning unit.

8. A surface cleaning apparatus having comprising:

(a) a surface cleaning head having a dirty air inlet;

(b) a longitudinally extending upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising first and second longitudinally spaced apart portable surface cleaning unit mounting members;

(c) a portable surface cleaning unit removably mounted to the upper portion and comprising an air treatment member and a suction motor;

(d) an above floor cleaning wand removably mounted to the upper portion; and

,

(e) a flexible air flow conduit forming at least part of an air flow path from the above floor cleaning wand to the portable surface cleaning unit

wherein all of the removable above floor cleaning wand has an absence of the first and second longitudinally spaced apart portable surface cleaning unit mounting members.

9. The surface cleaning apparatus of claim 8 wherein the first portable surface cleaning unit mounting member comprises a pair of laterally extending portions.

10. The surface cleaning apparatus of claim 8 wherein the second portable surface cleaning unit mounting member provides a support on which the portable surface cleaning unit seats when mounted to the upper portion.

11. The surface cleaning apparatus of claim 8 wherein the upper portion comprises a portion of an air flow path from the dirty air inlet to the above floor cleaning wand.

12. The surface cleaning apparatus of claim 8 wherein, the surface cleaning head comprises an air flow path from the dirty air inlet to a cleaning head outlet and when the above floor cleaning wand is mounted to the upper portion, an inlet end of the above floor cleaning wand faces the cleaning head outlet.

13. The surface cleaning apparatus of claim 12 wherein the air flow path from the dirty air inlet to the cleaning head outlet comprises a flexible hose.
