Abstract

L'invention concerne un ajutage (1) pour aspirateur, notamment pour aspirateur électrique, qui comprend un bord (4) associé à une surface d'aspiration (SF) lorsque l'aspirateur est en service. Afin de parvenir au meilleur pouvoir d'aspiration possible, tant en ce qui concerne les grosses impuretés que celles qui sont plus fines, il est prévu selon l'invention que le bord (4) soit constitué par une roue à alvéoles (5) dont l'axe de rotation (6) s'étend en direction du bord (4).
