L'invention vise à améliorer le dispositif d'aspiration de surfaces dures de telle manière qu'il produise un flux d'aspiration constant indépendamment du niveau de remplissage du réservoir à liquide souillé, et puisse être utilisé dans une orientation quelconque par rapport à la verticale. A cet effet, une chambre de dépôt (33) est disposée entre la buse d'aspiration et le groupe d'aspiration, celle-ci contient le dispositif de dépôt et se trouve en connexion fluidique avec l'orifice d'aspiration (48) de la buse d'aspiration au moyen d'une conduite d'aspiration (47), et avec le groupe d'aspiration au moyen d'une conduite à dépression. La chambre de dépôt est également connectée au réservoir de liquide souillé au moyen d'une ouverture d'écoulement de sortie (67). Dans la chambre de dépôt, les zones d'embouchure (51, 61) de la conduite d'aspiration (47) et de la conduite à dépression sont au moins partiellement entourées, dans le sens périphérique, par des espaces de stockage intermédiaires (71, 72, 73) pour liquide déposé.
