Abstract
A device for a vacuum cleaner having a vacuum source communicating with an inlet channel and an outlet channel for air flowing through the vacuum cleaner. The vacuum cleaner includes a holder (19) for a dust pick-up tool such as a feather-duster (20) or a micro fiber-type duster/. The holder is provided with a chamber (21) which, by operation of a valve (28,30), can be connected to the inlet or outlet channel so that the dust pick-up tool is cleaned by the air flowing through the chamber.
