View Patent ↗A surface cleaning apparatus comprises a surface cleaning head, an upright section moveably mounted to the surface cleaning head, and a portable cleaning unit removably mounted to the upright section and comprising an energy storage member and a portable cleaning unit suction motor. The energy storage member provides the portable cleaning unit suction motor with power at least when the portable cleaning unit is switched on and when the portable cleaning unit is removed from the upright section.
1. A surface cleaning apparatus comprising:
a) a surface cleaning head having a first dirty fluid inlet;
b) an upright section moveably mounted to the surface cleaning head between an storage position and a reclined in use position;
c) a portable cleaning unit removably mounted to the upright section and comprising at least one air treatment member, a first energy storage member and a portable cleaning unit suction motor; and,
d) a fluid flow path extending from the first dirty fluid inlet to the portable cleaning unit,
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 first energy storage member when removed from the upright section and is operable on power provided by the external source of power when mounted to the upright section.
2. The surface cleaning apparatus of claim 1 wherein the portable cleaning unit suction motor is operable on DC power.
3. The surface cleaning apparatus of claim 1 wherein one of the surface cleaning head and the upright section further comprises or is connectable to a power cord and the portable cleaning unit is powered solely by the first energy storage member when the portable cleaning unit is removed from the upright section.
4. The surface cleaning apparatus of claim 1 wherein one of the surface cleaning head and the upright section further comprises or is connectable to a power cord, the first energy storage member comprises one or more battery and the one or more battery is charged when the portable cleaning unit is mounted on the upright section.
5. The surface cleaning apparatus of claim 1 wherein the upright section is an up flow duct and the portable cleaning unit is a hand vacuum cleaner.
6. The surface cleaning apparatus of claim 1 wherein the portable cleaning unit suction motor is operable on DC power and the upstream suction motor is operable on AC power.
7. The surface cleaning apparatus of claim 6 wherein the portable cleaning unit suction motor is a dirty air motor and the upstream suction motor is a clean air motor.
