ABSTRACT:
An upright vacuum cleaner including a canister assembly pivotally connected to a nozzle assembly and an extensible hose which forms part of the vacuum path between the nozzle assembly and the canister assembly and which can be disconnected from the nozzle assembly for above-the-floor cleaning. Disconnecting the hose deenergizes an agitator motor in the nozzle assembly. The canister assembly includes a housing with an integral hand tool and attachment storage area which retains the tools and attachments, as well as the extensible hose, within the periphery of the housing. The upright vacuum cleaner also includes a height adjustment mechanism which deenergizes the agitator motor when the nozzle assembly is in its closest relation to the floor surface being cleaned.
