[0015]Preferably, the cross-sectional area of the air flow path through the rigid wand (in a plane transverse to the direction of air flow through the wand) is less than the cross-sectional area of the air flow path between the hand vacuum cleaner dirty air inlet to the air treatment member. An advantage of such a configuration is that the velocity of air travelling through the rigid wand in the floor cleaning mode may be greater than the velocity of air travelling through the upstream portion in the above floor cleaning mode.

Problems solved by technology
However, where the suction motor of a hand vacuum cleaner is powered by an onboard energy storage member (e.g. one or more rechargeable batteries), the weight and/or power output of the suction motor may be limited, e.g. due to the weight, cost, and/or other concerns of, e.g., the on board energy storage

Abstract
A reconfigurable surface cleaning apparatus includes a floor cleaning unit comprising a surface cleaning head, and a portable cleaning unit comprising an energy storage member and an inverted cyclone. The reconfigurable surface cleaning apparatus is operable in an above floor cleaning mode in which the portable cleaning unit is removed from the floor cleaning unit and in a floor cleaning mode in which the portable cleaning unit is mounted to the floor cleaning unit. In the floor cleaning mode. In the floor cleaning mode, the cyclone air inlet is located up to 20 inches above the floor.
