A bagless canister vacuum cleaner (A) includes a selectively removable dirt cup (D), and an airstream (S) flows rotationally through the dirt cup (D) between an interior wall (31) of the dirt cup (D) and a filter assembly (F) selectively mounted in the dirt cup (D) so that entrained contaminants are separated from the airstream (S) flowing through the dirt cup (D) and collected by the dirt cup (D). The filter lies substantially parallel to the support surface on which the vacuum cleaner (A) is supported. A cover member (74) is connected to the main housing (B), and the cover member (74) is selectively movable to and held in an operative position in covering relation with an open first end (32) of a dirt cup (D). The main housing (B) defines a base (150) conformed to self-support the main housing (B) on a support surface with the dirt cup (D) arranged with its open first end (32) at a higher elevation than is closed second end (34). The removable dirt cup (D) includes a handle (80) adapted for being held by a user, and the dirt cup (D) defines or includes a spout (58) to facilitate emptying dirt therefrom.

L'invention porte sur un aspirateur-traineau (A) sans sac comportant un bac (D) à poussière amovible et dans lequel le flux (S) d'air tourbillonne dans le bac (D) entre l'une de ses parois (31) intérieures et un filtre (F) monté dans le bac (D) pour que les contaminants entraînés se séparent du flux (S) d'air traversant le bac (D), et s'y déposent. Le filtre est sensiblement parallèle à la surface du support sur lequel repose l'aspirateur (A) . Un couvercle relié au boîtier (B) principal peut se placer en position de fonctionnement où il recouvre une première (32) extrémité ouverte de bac (D) à poussière. Le boîtier (B) principal est monté sur une surface de la base (150) de manière à ce que la première (32) extrémité ouverte du bac (D) à poussière soit plus haute que sa deuxième (34) extrémité fermée. Le bac (D) à poussière comporte une poignée (80) saisissable par l'utilisateur et un bec verseur (58) facilitant l'évacuation de la poussière.
