Abstract

L'invention concerne une balayeuse comprenant un corps principale doté d'une admission de débris, et une enveloppe de balai dotée d'un fond ouvert et d'un balai principal monté à l'intérieur de l'enveloppe de balai pour propulser les débris vers l'avant à partir de la surface en cours de nettoyage, ce qui crée un flux de débris propulsé en avant par la sortie de débris tournée vers l'avant. Un ensemble buse à soufflage d'air est doté d'une telle buse raccordée en communication fluidique à une source d'air sous pression pour en recevoir de l'air sous pression. L'invention concerne une installation de buse à soufflage d'air destinée à émettre de l'air vers l'avant et vers le bas, dans un rapport mobile sur l'enveloppe de balai en vue de son déplacement vers une position choisie parmi une pluralité de positions visées, la sortie de la buse à soufflage d'air étant contiguë à la zone de contact du balai principal.
