Patent

CA 2281241

A wet/dry vacuum appliance having enhanced air-handling performance and reduced operating noise is described. In one embodiment, the collector scroll in a wet/dry vacuum is configured so as to isolate the vacuum's impeller from geometries prone to increase operating noise at particular frequencies. Further, the overall geometry and configuration of the air flow path through the power head of the vacuum is such that air-handling performance is enhanced even as noise levels are reduced. In the disclosed embodiment, the wet/dry vacuum is of the detachable power head type, although non-detachable power head implementations are contemplated.
