Abstract: The device comprises a tubular container having a closed end and an opening at the opposite end. The roller is inserted in the container by way of this opening. The container has internally spacer elements capable of receiving the roller in a position spaced from the inner surface of the tubular wall of the container and rendering the container connected to the roller for rotation with the latter. There is at least one outer cylindrical rolling surface on the container. For removing liquid from the roller, the latter is placed in the container and the assembly comprising the container and the roller is rapidly rolled on a surface so that the mixture of water and paint is ejected from the roller by centrifugal force and received in the container.
