1. A surface cleaning apparatus comprising:
a hand vacuum cleaner comprising:
i. a main body comprising a bottom, a handle, the main body housing a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation; and,
ii. a cyclone unit provided on a front of the main body, the cyclone unit having a first stage cyclone, the first stage cyclone comprising a cyclone chamber having a front, a rear and a cyclone axis of rotation that extends between the front and rear of the cyclone chamber, wherein air enters the cyclone unit through a front wall of the first stage cyclone and air exits the cyclone chamber at the rear of the cyclone chamber;
a surface cleaning head having a front, a rear, a dirt air inlet and a cleaning head air outlet; and,
a rigid air flow conduit that is removably mountable to the surface cleaning head and, when attached to the hand vacuum cleaner and the surface cleaning head, extends between the cleaning head air outlet and a hand vacuum cleaner air inlet, the rigid air flow conduit having a longitudinally extending conduit axis which when attached to the hand vacuum cleaner, is parallel to the cyclone axis of rotation,
wherein the hand vacuum cleaner is removably mountable to a downstream end of the rigid air flow conduit and when the hand vacuum cleaner is mounted to the downstream end of the rigid air flow conduit, the handle is a driving handle for the surface cleaning apparatus.
