A vacuum cleaner having a thermal cutoff assembly. The assembly includes a temperature sensor disposed proximate to a motor of the vacuum cleaner. When the temperature sensor reaches a predetermined temperature, a switching element in the assembly disconnects power shutting off the vacuum cleaner. The vacuum cleaner cannot be restarted until its power source has been manually disconnected and reconnected.

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.
