  • Patent number: 8533903
    Abstract: A floor cleaning apparatus includes a housing having a nozzle assembly and a canister assembly. The nozzle assembly includes a suction inlet. Both a suction generator and a dirt collection assembly are carried on the housing. The dirt collection assembly includes a dirt cup, a shroud concentrically received within the dirt collection chamber defined by the dirt cup and at least one rib projecting from the shroud toward the bottom wall of the dirt cup. The rib is positioned so as to reduce air turbulence in the dirt collection chamber between an airflow guide on the shroud and the bottom wall of the dirt cup.

  • Publication number: 20040168282
    Abstract: The present invention relates to a nozzle assembly and to a vacuum cleaner incorporating that nozzle assembly. The nozzle assembly includes a housing having a main cavity and at least one intake opening in fluid communication with the main cavity. Additionally, the nozzle assembly includes an edge cleaning duct having an inlet adjacent an edge of the housing and an outlet in fluid communication with the main cavity. More specifically the housing includes first and second nesting sections that define a channel that functions as the edge cleaning duct. The vacuum cleaner incorporates the nozzle assembly described along with a canister assembly that is connected to the nozzle assembly. Both a suction generator and dirt collection vessel are carried on one of the canister assembly and the nozzle assembly. The suction generator draws air entrained with dirt and debris through the nozzle assembly to the dirt collection vessel before exhausting clean air back into the environment.
