ABSTRACT:
A wet/dry vacuum appliance having a non-cylindrical collection canister is disclosed. In one embodiment, the collection canister has substantially cylindrical ends and substantially flatter sides. A collection canister lid is adapted to engage the canister around a top perimeter thereof, supporting the canister such that the lid cooperates with the canister to resist the collapse of the canister when subjected to vacuum forces resulting from operation of the vacuum.
