Abstract
A vacuum cleaner is disclosed having a motor inlet conduit and sound deadening material disposed within the motor inlet conduit for reducing the overall noise level of the vacuum cleaner. The motor inlet conduit fluidly connects a dirt receptacle chamber and a motor inlet, and may have a generally continuous cross-sectional profile and one or more expanded regions for housing the sound deadening material. With the sound deadening material installed in the one or more expanded regions, the motor inlet conduit may form a smoothly changing profile along its entire length and reduce the overall noise level of the vacuum cleaner.
