Abstract

L'invention concerne un appareil d'aspiration pour surfaces dures (10/200), comprenant un dispositif d'aspiration (12/212) équipé d'une buse d'aspiration (14/214), d'une unité de séparation (16/216) et d'un groupe d'aspiration (18/218), et comprenant en outre un réservoir à liquide souillé (20/220) et une poignée (22/222). L'unité de séparation (16/216) présente une chambre de séparation (32/232), dans laquelle est disposé au moins un élément de séparation (36/236) et qui présente une entrée d'aspiration (34/234), une sortie de liquide (52/252) et une sortie d'air (40/240). L'entrée d'aspiration (34/234) est en liaison fluidique avec la buse d'aspiration (14/214), la sortie de liquide (52/252) est en liaison fluidique avec le réservoir à liquide souillé (20/220) et la sortie d'air (40/240) est en liaison fluidique avec le groupe d'aspiration (18/218). Afin que l'appareil d'aspiration pour surfaces dures (10/200) puisse être guidé par un opérateur sur une surface dure avec un apport minimum de force, la poignée (22/222) est disposée sous le dispositif d'aspiration (12/212) par rapport à la position posée de l'appareil d'aspiration de surfaces dures (10/200).
