A paint roller cleaner has a base for resting in a sink and a knob for receiving on its outside surface the inside surface of a paint-laden paint roller. The knob is adjustable relative to the base, and/or the roller is adjustable relative to the knob, so that the roller is vertical and water filing the roller will evenly and uniformly overflow and clean the roller outer surface. The knob may be an upstanding, tapered, hollow cylinder that rotates about a horizontal axis at its base to adjust its angle relative to the base, wherein the tapered cylindrical surface allows the cleaner to cooperate with variously-sized rollers. In another version, the knob is a hollow sphere, with its top end truncated, and with several spaced-apart vertical slits in its side, like a collet, for flexing/bending to various diameters to cooperate with variously-sized rollers. In another version, the knob is a sphere.
