  • Publication number: 20160355052
    Abstract: A device for cleaning a paint roller or other device is provided. The device includes an outer ring wall and an inner ring wall integrally connected to and located within the outer ring wall defining an opening for receiving an object. A plurality of holes is arranged in a circle on the inner ring wall for propelling liquid in a forward direction into the object. The device further includes a handle member integrally connected to and extending perpendicularly outward from the outer ring wall, the handle member adapted to be matingly engaged with a hose, the hose supplying the liquid to the plurality of holes. The handle member includes a hand grip portion and a trigger portion pivotally attached or coupled to the hand grip portion, the trigger portion adapted for movement between a no flow position and an open position.
