Abstract
A vacuum cleaner includes a body that carries a suction generator. A final filter is carried on the body downstream from the suction generator. The final filter is oriented along a first plane. Opposed side discharge outlets are carried on the body and oriented along a second plane substantially perpendicular to the first plane. Air is exhausted from the vacuum cleaner through succeeding compartments of increasing volume and rerouted or turned through different planes along a tortuous air path in order to muffle noise produced by the operating vacuum cleaner.
