Abstract

An all in the head surface cleaning apparatus can include a surface cleaning head having an air flow path extending from a dirty air inlet to a clean air outlet. The surface cleaning head can include a cyclone assembly comprising a cyclone chamber and a dirt collection chamber. The cyclone chamber may have a longitudinal cyclone axis, a cyclone air inlet and a cyclone air outlet. The dirt collection chamber may be moveable between an in use position and an emptying position. The surface cleaning head may include a pre-motor filter chamber and a suction motor. At least one of the pre-motor filter and a pre-motor filter chamber may be visible when the dirt collection chamber is in the emptying position. An upper portion may be mounted to the surface cleaning head between a storage position and a floor cleaning position, and may include a drive handle.
