Le flux d'air aspiré (30) est acheminé par un canal affluent (28) dans une chambre de collecte de poussière (18) du boîtier (2), puis acheminé par un canal d'évacuation (29) de ladite chambre de collecte de poussière (18) vers un raccord d'aspiration (26) du ventilateur aspirant (22). Pour pouvoir entretenir et changer facilement le rouleau de nettoyage, la chambre de travail (15) est fermée par un couvercle (5) de boîtier pouvant être ouvert, le rouleau de nettoyage (12) étant maintenu rotatif entre des bras de basculement (65, 66). Lesdits bras de basculement (65, 66) permettent de faire basculer le rouleau de travail (12) d'une position de travail dans la fente d'aspiration (14) à une position d'entretien située à l'extérieur de la fente d'aspiration (14). Lorsque le couvercle (5) du boîtier est fermé, les bras de basculement (65, 66) sont maintenus dans la position de travail par des éléments abaisseurs (83, 84) montés sur le couvercle (5) du boîtier.
