Abstract: The system is based on a roller (2) installed on a structure with two containers, one located above the other, such that the rotation of the roller (2) as it rests on the floor collects particles and liquids, sending the particles into the first container (1) where they are stored, while a squeezing element (9) squeezes the liquids collected by the roller into the second container (1?). Water is applied to the roller (2) from an upper tank (7) which discharges via a nozzle with a type of scraper (8) to prevent the roller (2) from rotating in the opposite direction and to clean off any particles stuck to it. At the top and rear of the container (1) there are flexible bristles (17) or mop strips that act as a broom and/or mop in the inverted position after turning and hinging the assembly. The assembly has a rotating handle (18) and a skid (13) to overcome obstacles and differences in levels.
