Cleaning device with aerodynamic oscillator

A cleaning device for cleaning a carpet having face yarns that extend over a distance of several millimeters from a generally planar backings to define a carpet surface, comprising:

• an oscillator unit, including:
• an oscillator;
• an oscillation space that is at least partially defined by or accommodates at least part of the oscillator, and that is accessible through a jet opening via which ambient fluid is alternatingly drawn into the oscillation space and expelled from the oscillation space during operation of the oscillator;
• a nozzle, including
• a support structure configured to support the nozzle against the carpet, including a carpet surface penetrator that defines said jet opening and protrudes from the support structure such that, in a supported condition of the nozzle in which the support structure is supported against a carpet, the carpet surface penetrator penetrates the carpet surface and the jet opening is disposed at least partially below the support structure and the carpet surface.
