Abstract

L'invention concerne un appareil de nettoyage local à mousse, ainsi qu'une machine à laver. Ledit appareil de nettoyage local à mousse comprend : un logement comportant une cavité de réception ; un ensemble de nettoyage à mousse, présentant une position de stockage et une position de nettoyage par rapport au logement, ledit ensemble étant logé dans la cavité de réception du logement lorsqu'il se trouve dans la position de stockage, et ledit ensemble se situant à l'extérieur de la cavité de réception du logement lorsqu'il se trouve dans la position de nettoyage ; un ensemble mobile, relié au logement et à l'ensemble de nettoyage à mousse et destiné à déplacer l'ensemble de nettoyage entre la position de stockage et la position de nettoyage. Selon l'invention, une fois que l'utilisation de l'appareil de nettoyage local à mousse est terminée, l'ensemble de nettoyage à mousse passe de l'extérieur à l'intérieur du logement au moyen de l'ensemble mobile, ce qui empêche l'ensemble de nettoyage de prendre beaucoup de place.
