Abstract: In order to keep the base surface of a cleaning system for industrially manufactured components as small as possible, it is provided that the process chambers (4, 5, 23) and the robot chamber (3) of the cleaning system are disposed on a base plate (7), wherein the base surface (8) of the base plate (7) is greater than the common base surface (9) of the process chambers (4, 5, 23) and the robot chamber (3), and at least two spatially separate hollow spaces (10, 11, 20) to accommodate the process fluids being provided in the base plate (7), wherein the hollow spaces (10, 11, 20) in each case extend at least partially below the process chamber (4, 5, 23) and extend at least partially outside the common base surface (9) of the process chambers (4, 5, 23) and the robot chamber (3), and at least one hydraulic component of a hydraulic circuit is disposed on the base plate (7) above at least one hollow space (10, 11, 20).
