  5. Procédé selon l'une quelconque des revendications 1 à 4, comprenant en outre, après que le moteur d'aspiration s'est arrêté de fonctionner, l'étape consistant à arrêter l'élément de pression mobile (310) après avoir déplacé l'élément de pression mobile (310) vers un côté de l'élément fixe (320) fixé dans l'unité de collecte de poussière.
  6. Procédé selon la revendication 5, dans lequel l'élément de pression mobile est un élément rotatif (310) et tourne dans l'unité de collecte de poussière (200).
  7. Procédé selon la revendication 6, dans lequel l'élément rotatif (310) se déplace vers la première surface de l'élément fixe (320) lorsque le moteur d'aspiration arrête de fonctionner.
  8. Procédé selon la revendication 7, dans lequel la première surface de l'élément fixe (320) fait face à une direction de rotation de l'élément rotatif (310).
  9. Procédé selon la revendication 8, dans lequel, après que l'élément rotatif (310) s'est déplacé vers la première surface de l'élément fixe (320), l'élément rotatif (310) se déplace vers une seconde surface de l'élément fixe (320) et s'arrête.
  10. Procédé selon la revendication 6, comprenant en outre un élément rotatif supplémentaire, dans lequel, lorsque le moteur d'aspiration arrête de fonctionner, l'un des éléments rotatifs s'arrête après s'être déplacé vers une première surface de l'élément fixe (320) et l'autre des éléments rotatifs s'arrête après s'être déplacé vers une seconde surface de l'élément fixe (320).
