The device has brush or knob-like cleaner heads (16). Most of the heads are positioned in a row. A distance bar (18) with fewer or without cleaner heads projects to one side from the head row. The distance bar is T-shaped relative to projecting arms (14) of the filter cleaner, which carry the cleaner head rows. The distance bar forms foot (26), which defines at least two support points. These are positioned at a relative distance on a straight line at right angles to the cleaner head row. The cleaner heads are pretensioned elastically against the filter covering. |
