A surface cleaning apparatus comprises a base comprising an AC suction motor and a portable cleaning unit removably mounted on the wheeled base and comprising an energy storage member and a portable cleaning unit suction motor that is operable on DC power. The AC suction motor provides motive power when the surface cleaning unit is switched on and when the portable cleaning unit is mounted on the base. The portable cleaning unit suction motor provides motive power when the portable cleaning unit is switched on and when the portable cleaning unit is removed from the base. Alternately, the portable cleaning unit suction motor may be operable on DC power when removed from the wheeled base and may be operable on power provided by the wheeled base when mounted on the wheeled base.
