  • Patent number: 6807708
    Abstract: An upright vacuum cleaner includes a nozzle assembly having a nozzle cavity and a canister assembly pivotally connected to the nozzle assembly. A dust bag is carried by the canister assembly. A dirty air pathway provides fluid communication between the nozzle cavity and dust bag. A suction generator generates a vacuum for drawing dirt and debris from the nozzle cavity, through the dirty air pathway to the dust bag. The dirty air pathway includes dual suction ports carried on the nozzle assembly in fluid communication with the nozzle cavity, a splitter carried on the canister assembly, dual suction hoses in fluid communication between the dual suction ports and the splitter, a removable bag mount carried on the canister assembly and a feed conduit on the canister assembly which provides fluid communication between the splitter and the removable bag mount.
