Abstract
A vacuum cleaner nozzle includes a housing with, formed on an underside of the housing and extending in a transverse direction, a suction orifice that is bounded by what in a working direction aligned perpendicular to the transverse direction is a front suction-orifice edge and by what in the working direction is a rear suction-orifice edge, with a suction duct disposed in the housing and adjoining the suction orifice, with a suction port extension, which is also fluidically in communication with the suction duct and is disposed, relative to the working direction, on a rear side of the housing. The vacuum cleaner nozzle further includes a secondary air aperture disposed in front of the suction orifice and fluidically in communication with the suction duct. The secondary air aperture is at least partly covered by a flexible textile valve element.
