1. An upright surface cleaning apparatus comprising:
- (a) an air flow path extending from a first dirty air inlet to a clean air outlet and comprising a cleaning wand having the first dirty air inlet, a first dirty air outlet and a flexible air flow conduit downstream of the first dirty air outlet;
(b) a surface cleaning head having a front end having a second dirty air inlet, a rear end having a second dirty air outlet, and a cleaning head air flow conduit positioned between the second dirty air inlet and the first dirty air outlet;
(c) a support structure moveably mounted to the surface cleaning head between a floor cleaning position and a storage position, the support structure comprising a support shaft; and
,(d) a cleaning unit comprising a suction motor, an air treatment member, a bottom and a mount having a downwardly facing opening and an upwardly facing opening, wherein the support shaft is slidably receivable in the downwardly facing opening and the first dirty air inlet of the cleaning wand is receivable in the upwardly facing opening, the cleaning unit being positioned in the air flow path downstream from the flexible air flow conduit and removably seated on the support shaft wherein, when the support structure mount is slid onto the support shaft when in a substantially upright orientation, the suction motor is below the air treatment member, the bottom of the cleaning unit is spaced from the surface cleaning head to define an open area at a front end of the cleaning unit wherein the open area is visible to a person positioned forward of the apparatus and wherein the cleaning unit will remain in place until lifted off,wherein the upright surface cleaning apparatus has at least two operating modes comprising;
(i) a first upright operating mode wherein the upright surface cleaning apparatus is operable with the cleaning unit seated on the support structure and the first dirty air inlet of the cleaning wand is seated in the upwardly facing opening whereby the wand and the support shaft are axially aligned, and,(ii) a second operating mode wherein the cleaning unit is operable when removed from the support structure, the first dirty air inlet of the cleaning wand is removed from the mount, and the cleaning wand and the flexible hose form part of the air flow path extending from the first dirty air inlet to the clean air outlet.

11. An upright surface cleaning apparatus comprising:
-
(a) a surface cleaning head having the dirty air inlet; (b) a support structure comprising an upwardly extending projection, the support structure being moveably mounted to the surface cleaning head and downstream of the dirty air inlet; and
,(c) a cleaning unit removably mounted to the support structure, the cleaning unit comprising a suction motor positioned beneath an air treatment member, a cleaning wand, a flexible air flow conduit, and a mount having a downwardly facing opening and an upwardly facing opening, wherein the support shaft is slidably receivable in the downwardly facing opening and a dirty air inlet of the cleaning wand is receivable in the upwardly facing opening, wherein when the mount is in an upright orientation and the upwardly extending projection is slid into the annular opening of the mount, the cleaning unit will remain in place until lifted off the support structure and wherein when the end of the wand is in the annular opening, the wand is positioned over the upwardly extending projection. - View Dependent Claims (12, 13)
