A cleaning apparatus (10) for removing residual paint from flow passages in a spray painting system comprises a flow passage (12) for conveying paint to a spraying device (14) and a manifold (16) defining a plurality of individual inlets (17) into the flow passage. At least two different paints are supplied to the manifold through the inlets. A solvent supplier (20) supplies a variable pressure and variable volume flow of solvent to the manifold (16) during a cleaning cycle to remove residual paint from the manifold and the flow passage (12) after a completed painting cycle to prepare for a new cycle. The assembly is characterized by including a constant volume flow controller (22) for maintaining a constant volume flow of solvent upstream of the manifold (16) independent of solvent pressure fluctuations.
