ABSTRACT:
The vacuum cleaner nozzle of the invention is provided with a nozzle body equipped with a suction pipe connecting piece and with a bottom plate which closes off the nozzle body towards the bottom, whereby at least one flow channel which is open towards the bottom and lets out into a central suction channel connected to the pipe connecting piece is located in the bottom plate. The flow channel is here double-parabolic in profile, meaning that it is parabolic in its cross section as well as in its longitudinal section extending perpendicularly to the bottom plate in relation to the longitudinal axis of the flow channel. The cross-section increases in this case from the bottom of the flow channel in the direction of the floor and from the end of the flow channel away from the suction channel in the direction of said suction channel. Thanks to this configuration of the suction channel, even distribution of the suction capacity is achieved over the entire width of the vacuum cleaner nozzle.
