A vacuum appliance, comprising:
- a housing;
- an intake port fixedly attached to said housing;
- a first plurality of attachment nodes radially spaced about said intake port at a proximal end, wherein a distal end of said intake port further comprises an elongated portion adjacent to and axially spaced from said plurality of attachment nodes, said elongated portion having a continuous generally tubular surface having a diameter smaller than said proximal end;
- and
- an accessory having proximal and distal ends, said proximal end comprising a plurality of axially located grooves for selectively engaging said plurality of attachment nodes to establish a locking relationship with said intake port.
