Abstract:
1. 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.
