Vacuum cleaner bag docking assembly

A vacuum bag comprising:

• a generally flat collar;
• a first opening in the collar configured to accept a dirty air nozzle;
• a second opening in the collar elongated in a first direction;
• a third opening in the collar elongated in a second direction where the second and third openings are configured to allow the vacuum bag to be moved into a fully installed position onto the dirty air nozzle when the collar is in a correct orientation.

A vacuum cleaner comprising;

• a dirty air nozzle;
• a vacuum bag having a substantially rigid collar having a dirty air opening, wherein the rigid collar has at least one void, in addition to the dirty air opening, used for alignment of the collar;
• a mounting member releasably connected to the vacuum cleaner and movable between a loading position in which the vacuum bag is inserted into or removed from the mounting member and a fully closed position in which the dirty air nozzle engages the dirty air opening in the collar of the vacuum bag;
• at least one protrusion fixedly positioned adjacent to the dirty air nozzle and configured to preventing the mounting member from reaching the fully closed position when the collar of the vacuum bag is in an incorrect orientation by interfering with a solid area of the collar, the at least one protrusion allowing the mounting member to reach the fully closed position when the collar of the vacuum bag is in a correct orientation by passing through the corresponding at least one void.
