Abstract

La présente invention concerne un dispositif de nettoyage de sols et d'élimination de liquides, comprenant un tambour rotatif creux (20) dont la surface externe est recouverte d'un matériau d'absorption des liquides (28). Un rouleau de pression (30) est monté rotatif contre le tambour de manière à comprimer le matériau d'absorption des liquides lorsque le tambour tourne, pour faire sortir le liquide du matériau. Le liquide est recueilli dans un bac (40) à partir duquel il s'écoule par gravité par un tube (130) pour atteindre un essieu de tambour creux (23) et de ce fait l'intérieur du tambour. Le tambour peut être vidé par enlèvement d'un couvercle de l'extrémité de l'essieu creux et par inclinaison du dispositif sur le côté.
