(ii) an upper section moveably mounted to the surface cleaning head between an upright storage position and a rearwardly inclined floor cleaning position;
(iii) a charger having an energy storage member; and,
(iv) an air flow path extending from the dirty air inlet to a floor cleaning unit air outlet; and,

(b) a portable surface cleaning unit connectable to the floor cleaning unit, the portable surface cleaning unit comprising a portable surface cleaning unit air inlet connectable in air flow communication with the floor cleaning unit air outlet, a main body, an air treatment member, a suction motor, a handle and a capacitor,
wherein,
when fully charged, the energy storage member stores sufficient stored power to recharge the capacitor at least twice;
when the portable surface cleaning unit is connected to the floor cleaning unit,
