A roller brush (9) is horizontally arranged in a solvent vessel (7). The essentially vertical portions of the lateral surface of the brush (9) are sealingly surrounded by contour plates (11,12). The contour plates are sealingly connected to a cover (14-16) which is in turn sealingly connected to the edge of the vessel. The brush (9) is partially immersed in the solvent and is driven for rotation. The contour plate (11) which is conjoined to the upwardly moving peripheral portion of the rotating brush (9), extends down into the solvent so that the brush, in cooperation with the contour plate (11), pumps solvent up to the scrubbing area as the brush rotates. A conveyor path (1) for objects to be cleaned extends through the upper peripheral portion of the brush. The bristles of the brush (9) form, in cooperation with the cover (14-16) and the contour plates (11,12), a seal between the interior of the vessel and the surroundings of the vessel.
