ABSTRACT:
A paint conduit has a conduit wall enclosing an interior and a cleaning device that has a hose arranged in the interior and a pressurized fluid source connected to the hose. The hose is expandable at least in a radial direction of the hose and is inflated by the pressurized fluid source to displace the paint, present in the paint conduit, from the paint conduit when new paint is to be conveyed through the paint conduit.
