Abstract

An all in the head surface cleaning apparatus may 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 may include a cyclone including a cyclone chamber and a longitudinal cyclone axis. The surface cleaning head may include a pre-motor filter chamber housing a pre-motor filter. The pre-motor filter may have an upstream face, a downstream face and a pre-motor filter axis that is generally parallel to the upstream and/or downstream face. The surface cleaning apparatus may have a suction motor having a first end, a second end, a suction motor inlet and a suction motor axis extending between the first and second ends. The cyclone axis may be oriented generally transverse to a forward direction of travel and the pre-motor filter axis may be generally parallel to the forward direction of travel.
