In a vacuum cleaner (1) particulate matter (32) accumulates on a counter- weighted flap (4). When the weight of the particulate matter (32) exceeds the effect of the counterweight (15) and the effect of any air-pressure differential across the flap (4), the flap opens and voids particulate matter (32) from within the vacuum cleaner (1).

Lorsque le poids de la matière particulaire (32) dépasse l'effet du contrepoids (15) et l'effet d'un quelconque différentiel de pression d'air à travers le volet (4), le volet s'ouvre et vide la matière particulaire (32) depuis l'intérieur de l'aspirateur (1).
