    Abstract: A reconfigurable surface cleaning apparatus includes a floor cleaning unit comprising a surface cleaning head, and a hand vacuum cleaner. The reconfigurable surface cleaning apparatus is operable in a floor cleaning mode in which the hand vacuum cleaner is mounted to a rigid wand of the floor cleaning unit and operated using an energy storage member of the hand vacuum cleaner, and also operable in an above floor cleaning mode in which the hand vacuum cleaner is disconnected from air flow with the floor cleaning unit and operated using the energy storage member. A cross-sectional area through the rigid wand is less than a cross-sectional area through an upstream portion of an airflow path of the hand vacuum cleaner. A velocity of air travelling through the wand in the floor cleaning mode is greater than a velocity of air flow through the upstream portion in the above floor cleaning mode.

    Abstract: An upright extractor has an upright section moveably mounted to a surface cleaning head. The upright section has a wand and hose assembly and a liquid separator. The liquid separator comprises a solid collection chamber that is separated from a liquid collection chamber by a porous divider. The upright extractor is operable in a floor cleaning mode in which the handle is a driving handle of the upright extractor. The upright extractor is also operable in an above floor cleaning mode in which the inlet end of the wand is disconnected from fluid flow communication with the surface cleaning head dirty fluid inlet and an above floor air flow path extends from the inlet end of the wand to the clean air outlet and the liquid separator and the suction motor are provided in the above floor cleaning air flow path.
