A self-powered nozzle assembly for use within a tank has a stationary body and a rotatable body rotatably connected to and in fluid communication with the stationary body. The rotatable body has an axis of rotation with at least one offset nozzle such that, as fluid is ejected from the at least one offset nozzle, the fluid applies a rotational force to the rotatable body. A rotational speed dampener is connected to the rotatable body. The rotational speed dampener has a hydraulic cylinder, and a piston positioned within the hydraulic cylinder. The piston is connected to the rotatable body at a point offset from the axis of rotation such that as the rotatable body rotates, the piston moves within the hydraulic cylinder. A fluid bypass permits fluid within the hydraulic cylinder to flow from the first chamber of the hydraulic cylinder to the second chamber.
