Method of assembling a vacuum cleaner

A method of assembling a vacuum cleaner housing, the method comprising the steps of:

• providing a first motor housing portion and a second motor housing portion which cooperate to enclose a motor, wherein said first and second motor housing portions each comprise a mating surface and a fastening element which is of one piece with said first and second motor housing portions respectively;
• positioning said first and second motor housing portions adjacent each other;
• advancing said first and second motor housing portions toward each other;
• manually elastically deforming said fastening elements of at least one of said first and second motor housing portions as said first and second motor housing portions are advanced toward each other;
• snapping said fastening elements together as said mating surfaces contact each other to form a complete motor housing wherein said first and second motor housing portions when secured to each other provide an annular extension;
• providing a nozzle base for supporting said motor housing;
• positioning said motor housing on said nozzle base;
• providing a lock ring;
• providing an extension on said nozzle base;
• providing said annular extension of said motor housing onto said nozzle base extension;
• and,
• snapping said lock ring onto said annular extension of said first and second motor housing portions and said nozzle base extension to secure them together.

A method of replacing an associated dirt bag within a vacuum cleaner housing, the method comprising:

• providing a vacuum cleaner housing selectively containing a dirt bag and comprising at least first and second discrete housing members, said first housing member having a first mating surface and first assembly means, which is of one piece with said first housing member, for selectively securing said first and second housing members into a housing, said second housing member having a second mating surface and a second assembly means, which is of one piece with said second housing member, for selectively securing said first and second housing members into a housing, said first assembly means comprising a first tab at a first end of said first housing member and a second tab at a second end of said first housing member, said second assembly means comprising a first slot at a first end of said second housing member and a second slot at a second end of said second housing member;
• manually elastically deflecting a top edge of said first housing member away from said second housing member until said second tab is displaced from said second slot;
• distancing said first housing member from said second housing member;
• removing a full dirt bag;
• installing an empty dirt bag;
• inserting said first tab of said first housing member into said first slot in said second housing member;
• advancing said second tab of said first housing member toward said second slot of said second housing member;
• and,
• manually elastically deflecting said top edge of said first housing member so that said second tab is received into said second slot.
