ABSTRACT:
An electric vacuum cleaner has a floor engaging unit, a generally vertically extending handle assembly pivotally affixed to the rear of the floor engaging unit, and a porous bag assembly mounted to the front of the handle assembly. The handle assembly is hollow to direct dust-laden air from the floor engaging unit to the bag assembly. A bottom plate, under the brush roll, has notches at its edges to enhance edge cleaning, and front wheels for the cleaner. Ridges are provided in the floor engaging unit to prevent inproper assembly of the drive belt. The handle assembly is resiliently biased upwardly, and a release is provided thereon to enable relaxation of forces on the porous bag of the porous bag assembly, to facilitate changing of the bag.
