Abstract: A painter roller cleaner structure wherein such structure is suitable for connection to a water hose or other solvent delivery system, this for the purpose of cleaning the nap of the roller to be cleaned. The structure includes a container having an open end and also a closed end provided with an inlet port. The wall of the container at such open end is provided with a detent slot for receiving the handle of an applicator. Once a roller, mounted on such applicator, is disposed within the container of the device, then the handle of the applicator is locked in place in the detent slot. Thereafter, pressured solvent may be supplied the container to wash the nap of the roller contained therein. A spacer sleeve may be included about the nap of the roller, for undersized rollers, whereby to direct incoming liquid-flow longitudinally and centrally about and through the roller nap. The spacer sleeve is retained in place by the structure illustrated.
