b. a portable cleaning unit removably mounted to the base and comprising at least one air treatment member, a portable cleaning unit energy storage member and a portable cleaning unit suction motor; and,
c. a fluid flow path extending from the first dirty fluid inlet to the portable cleaning unit,
wherein the portable cleaning unit suction motor is operable on power provided by the portable cleaning unit energy storage member when the portable cleaning unit is removed from the base, and
wherein the base energy storage member charges the portable cleaning unit energy storage member when the portable cleaning unit is mounted to the base.
8. The surface cleaning apparatus of claim 7 wherein the base further comprises or is connectable to a power cord and the portable cleaning unit is powered solely by the portable cleaning unit energy storage member when the portable cleaning unit is removed from the base.
9. The surface cleaning apparatus of claim 7 wherein the base further comprises or is connectable to a power cord and the portable cleaning unit energy storage member is charged when the portable cleaning unit is mounted to the base.
10. The surface cleaning apparatus of claim 7 wherein the upright section is an up flow duct and the portable cleaning unit is a hand vacuum cleaner that is removeably mounted to an outlet end of the up flow duct.
11. The surface cleaning apparatus of claim 7 , wherein the portable cleaning unit further comprises or is connectable to a power cord and the portable cleaning unit suction motor is also operable on power provided by an external source of power when the portable cleaning unit is removed from to the base.
12. The surface cleaning apparatus of claim 7 , wherein at least one of the surface cleaning head, the upright section and the portable cleaning unit is connectable to an external source of power, the portable cleaning unit suction motor is operable on power provided by the base energy storage member when the portable cleaning unit is removed from the upright section and wherein the portable cleaning unit suction motor is operable on power provided by the external source of power when the portable cleaning unit is mounted to the base.
13. A surface cleaning apparatus comprising:
