Abstract
An upright vacuum cleaner is provided which includes a sound muffler which, according to one aspect of the invention, may be combined with an accessory selector valve. The vacuum cleaner includes a height adjustment mechanism which eliminates positioning detents along the cam adjustment surface. The vacuum cleaner also includes a vacuum bag mounting arrangement which insures that the bag will not project above a handle parting plane, thus reducing the size of the shipping carton.
