Abstract

L'invention concerne une combinaison d'un mini-aspirateur (1), qui comprend un premier dispositif dépoussiéreur (10), une soufflante destinée à produire un flux d'air aspiré à travers le premier dispositif dépoussiéreur (10) et un moteur électrique (25) destiné à entraîner la soufflante, et d'un châssis d'aspirateur-balai (40), le mini-aspirateur (1) pouvant être relié au châssis d'aspirateur-balai (40) pour former un tout pouvant fonctionner à la manière d'un aspirateur-balai et le mini-aspirateur (1) pouvant être relié au châssis d'aspirateur-balai (40) de sorte qu'au moins une partie du flux d'air aspiré, produit par la soufflante, peut être dirigé à travers un second dispositif dépoussiéreur. L'invention concerne également un mini-aspirateur de ce type ainsi qu'un châssis d'aspirateur-balai réalisé de manière correspondante. Lorsque l'on fait fonctionner l'invention comme un aspirateur-balai plutôt que comme un mini-aspirateur, il est possible d'améliorer l'effet de filtration de l'air et/ou la puissance d'aspiration.
