Surface cleaning apparatus

An upright surface cleaning apparatus having a front, a rear and opposed lateral sides, the upright surface cleaning apparatus comprising:

• a) a dirt inlet provided in a surface cleaning head, the surface cleaning head having a front end and a rear end, the surface cleaning head is moveable in a forward direction;
• b) an upper section movably connected to the surface cleaning head via a coupling portion, the upper section is moveable between a floor cleaning position, in which the upright surface cleaning apparatus is useable for cleaning a floor, and a storage position in which the upright section is maintained in an upright position relative to the floor;
• c) a cleaning unit removably mounted to the upper section, the cleaning unit comprising an air treatment member, a suction motor, a clean air outlet and a front side, wherein the cleaning unit is usable in both a mounted and an unmounted configuration;
• d) an air flow path extending from the dirt inlet to the clean air outlet and comprising the air treatment member and the suction motor;
• e) an anti-rotation locking mechanism that automatically engages when the upper section is moved into the storage position;
• wherein the cleaning unit is removable while the upper section is in the storage position, and
• wherein the upper section is also moveably mounted with respect to the surface cleaning head whereby a direction that the front side of the cleaning unit faces is adjustable with respect to a direction that the front end of the surface cleaning head faces and the storage position includes a storage orientation in which the front side of the cleaning unit faces the same direction as the front end of the surface cleaning head and,
• wherein when the cleaning unit is mounted to the upper section and the upper section is in the floor cleaning position, the direction that the front side of the cleaning unit faces relative to the direction that the front end of the surface cleaning head faces is adjustable, and
• wherein the anti-rotation locking mechanism inhibits changes in the direction that the front side of the cleaning unit faces relative to the direction that the front end of the surface cleaning head faces once the upper section is in the storage position.
