Abstract:
An upright surface cleaning apparatus has a front end, a rear end and opposed lateral sides and a surface cleaning head having a dirt inlet and rear wheels. The rear wheels have an axis of rotation and a radius. The surface cleaning apparatus also includes an upper section and an upper section mount. The upper section mount movably mounts the upper section to the surface cleaning head at a position forward of the axis of rotation of the rear wheels. The surface cleaning head is movable between an floor cleaning position and a storage position. The surface cleaning apparatus includes an air flow path extending from the dirt inlet to a clean air outlet with a suction motor and a treatment member provided in the air flow path. The air flow path comprises a hose extending between the surface cleaning head and the upper section.
