Abstract

L'invention concerne un dispositif de nettoyage à haute pression destiné à être monté sur une machine à nettoyer à haute pression de type commercial et sur un aspirateur d'eau de type commercial. Ce dispositif comprend un capot de nettoyage (1), muni de préférence de roulettes (18), déplaçable sur une surface à nettoyer, et comportant des moyens d'étanchéité (17) montés sur le bord inférieure périphérique et maintenus en contact élastique avec le sol à nettoyer, ainsi qu'au moins une, mais de préférence, plusieurs buses à liquide (14) fixes, montées dans le carter (1), et un dispositif d'aspiration (5, 6, 7, 8) destiné à aspirer le liquide de nettoyage qui est sorti des buses (14) et s'est chargé d'impuretés. Un dispositif d'amenée (15) définissant des limites, de préférence polygonal, monté à l'intérieur du capot (1) est orienté de façon à converger vers l'orifice d'aspiration (7), de telle façon que le liquide de nettoyage sortant soit amené fonctionnellement, par contrainte, essentiellement vers l'orifice d'aspiration (7), les moyens d'étanchéité (16) du dispositif d'amenée étant de préférence en saillie, élastiquement à l'encontre des moyens d'étanchéité (17) du capot.
