Eric Muhlenkamp - Danville KY, US

International Classification:

A47L009/02

US Classification:

015/415100

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.
