ABSTRACT:
A hand-held corded vacuum cleaner having a housing with a motor compartment containing a motor mounted on partitions defining inlet, cooling and outlet chambers for efficient motor cooling by air which enters inlet and exits outlet vents in the inlet and outlet chambers, respectively. A dirt channel extends from a fan chamber having a fan mounted by being swaged on a motor shaft. A nozzle chamber is disposed at one end of the housing and a bag assembly is removably detached from the rear of the housing by means of a collar having a side hole through which a detent extends and which may be depressed to remove the bag assembly. The nozzle is in communication with the fan chamber and the fan pushes dirt through a dirt channel over the motor compartment into the bag of the bag assembly. The motor shaft has a pulley at the end thereof which is connected to a brush which is releasably retained in the nozzle compartment. A belt extends around the brush and the pulley. A door provides access to the belt and has a post which is coaxial with the motor shaft and extends into the immediate proximity of the end thereof to prevent the belt from meandering off the shaft. A well in the belly of the housing and a cooperating well defined between projections on the handle provide a receptacle for the line cord when it is wound around the housing and handle.
