Abstract
A canister vacuum cleaner improved by noise dampening means interposed between the outlets of its internal vacuum pump and the air outlet from the canister. The noise dampening means may comprise a baffle interposed between the pump outlets and air outlet of the canister in a manner which provides little resistance to a flow of air from the pump outlets to the air outlets of the canister. Further means which may comprise further baffles may be provided to dampen noise from the pump driving electric motor and motor cooling fan.
