Abstract: The present invention is a device for cleaning a roller of a paint roller applicator, while the roller is secured to a handle of the roller applicator. The cleaning device includes a vertically oriented tubular housing having an open top through which the roller is inserted into the housing for washing, and having an open bottom through which used washing fluid and material exit the housing. A sprayer assembly is provided for directing a stream of washing fluid against the roller when disposed within the housing to clean and rotate the roller on the handle. A cap for closing the top of the housing, is arranged to support the roller applicator so that the roller extends within the housing for washing. The cap has a laterally opening slot through which the handle extends when the roller is disposed within the housing. The cap is further arranged to adjustably fix the position of the handle of the roller applicator to align the roller with the fluid stream.
