<p>A cleaning device (1) for cleaning a carpet (70) having face yarns (74) that extend over a distance of several millimeters from a generally planar backing (72) to define a carpet surface (76), comprising:
an oscillator unit (30), including:
an oscillator (32);
an oscillation space (34) defined by or accommodating at least part of the oscillator, and
accessible through a jet opening (36) via which ambient fluid is alternatingly drawn into the oscillation space and expelled from the oscillation space during operation of the oscillator;
a nozzle (10), including
a carpet surface penetrator (14) that defines said jet opening;
a support structure (12) configured to support the nozzle against the carpet, such that, in a supported condition of the nozzle against the carpet, the penetrator penetrates the carpet surface and the jet opening is disposed at least partially below the carpet surface.</p> |
