8. An all in the head surface cleaning apparatus of claim 1 comprising:

(a) a surface cleaning head comprising;

(i) a rear end, a front end positioned forwardly of the rear end, an upper surface, and first and second laterally opposed sidewalls;

(ii) a dirty air inlet;

(b) a portable cleaning unit removably mounted to the surface cleaning head, the portable cleaning unit comprising;

(i) an air treatment member assembly comprising an air treatment member;

(ii) a suction motor having a suction motor axis, the cleaning unit being at least partially seated within the surface cleaning head when mounted to the surface cleaning head in a floor cleaning position, the portable cleaning unit being usable for cleaning when removed from the surface cleaning head; and

,

(iii) a clean air outlet downstream from the suction motor;

(c) a first air flow path extending between the dirty air inlet and the clean air outlet when the portable cleaning unit is in the floor cleaning position, the first air flow path including the air treatment member and the suction motor; and

(d) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle

wherein the air treatment member assembly comprises a cyclone assembly and the air treatment member comprises a cyclone chamber having a longitudinal cyclone axis that extends between the first and second laterally opposed sides.

9. The apparatus of claim 1 wherein the surface cleaning head further comprises a rotating cleaning brush and a brush motor, the brush motor having a brush motor axis wherein the brush motor is positioned forward of the suction motor.

10. The apparatus of claim 9 wherein the brush motor axis and the suction motor axis extend generally transverse to the forward direction and wherein the brush motor is laterally spaced from the air treatment member.

11. The apparatus of claim 1 further comprising a biasing member biasing the portable cleaning unit away from the floor cleaning position.

5. An all in the head surface cleaning apparatus comprising:

(a) a surface cleaning head comprising;

(i) a rear end, a front end positioned forwardly of the rear end, an upper surface, and first and second laterally opposed sidewalls;

(ii) a dirty air inlet;

(b) a portable cleaning unit removably mounted to the surface cleaning head, the portable cleaning unit comprising;

(i) an air treatment member assembly comprising an air treatment member;

(ii) a suction motor having a suction motor axis, the cleaning unit being at least partially seated within the surface cleaning head when mounted to the surface cleaning head in a floor cleaning position, the portable cleaning unit being usable for cleaning when removed from the surface cleaning head; and

,

(iii) a clean air outlet downstream from the suction motor;

(c) a first air flow path extending between the dirty air inlet and the clean air outlet when the portable cleaning unit is in the floor cleaning position, the first air flow path including the air treatment member and the suction motor; and

(d) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle
