Two motor upright vacuum cleaner
First Claim
1. A vacuum cleaner comprising:
- a canister assembly having an inlet opening;
a nozzle assembly mounted to the canister assembly including a nozzle with an agitator brush driven by an agitator motor, and an air suction passageway terminating at the nozzle, said air suction passageway having an open end opposite the nozzle;
a hose operatively connecting the inlet opening of the canister assembly to the open end of the air suction passageway during a first mode of operation, said hose having a collar releasably connectable to the open end of the air suction passageway such that said hose can be removed from said open end during a second mode of operation; and
a switch means electrically responsive to the connection of the collar of the hose to the open end of the air suction passageway without regard to the angular orientation of the collar relative to the air suction passageway which deenergizes the agitator motor when the collar is disconnected from the air suction passageway.

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.

10. In a vacuum cleaner having a canister assembly having an inlet opening, a nozzle assembly mounted to the canister assembly including a nozzle with an agitator brush driven by an agitator motor in the nozzle and an air suction passageway terminating at the nozzle, and a hose operatively connecting the inlet opening of the canister assembly to the air suction passageway during a first mode of operation, said hose being releasably connectably to the air suction passageway such that said hose can be removed from said air suction passageway during a second mode of operation, the improvement comprising:
a switch means electrically responsive to the connection of the hose to the air suction passageway without regard to the angular orientation of the hose relative to the air suction passageway which deenergizes the agitator motor when the hose is disconnected from the air suction passageway.
