Abstract
A plurality of nozzles is mounted inside a casing for projecting air jets through adjacent rows of stiff and upwardly projecting bristles of a carpet for dislodging lint between the bristles. The lint which is projected out of the bristles is sucked away through an aperture in the casing. The casing is manually or automatically moved over the carpet. The nozzles are characterized by hollow cylindrical needles extending between the bristles and are dimensioned to prevent lateral shifting of the bristles.
