Abstract

Une unité d'aspirateur (N) pour nettoyer un tapis comprend une ouverture d'aspiration (O), et un agitateur (Ai) dans l'ouverture d'aspiration (O) pour ouvrir des poils du tapis de telle sorte que la poussière peut être aspirée, et pour brosser les particules de poussière hors des poils. L'agitateur (Ai) a un axe de rotation (RA) qui est perpendiculaire à une surface à nettoyer, ou à un angle par rapport à la surface entre 90° et 45°. De préférence, de multiples agitateurs sont présents. De préférence, au moins l'un des agitateurs (Ai) a une direction de rotation qui diffère d'une direction de rotation d'au moins un autre des agitateurs. De préférence, des agitateurs voisins (Ai) sont interdigités. Avantageusement, l'ouverture d'aspiration (O) présente un rebord avant (FR) et un rebord arrière (RR), et l'agitateur (Ai) touche une surface à nettoyer à une position qui est plus proche du rebord avant (FR) que du rebord arrière (RR). L'agitateur (Ai) comprend avantageusement une pluralité de pattes, chaque patte ayant une première partie reliée à un centre de l'agitateur (Ai) et une partie d'extrémité à un angle par rapport à la première partie. La partie d'extrémité peut être constituée d'un matériau souple ou d'une brosse. L'invention concerne également un aspirateur équipé d'une buse d'aspirateur formée par une telle unité d'aspirateur (N).
