The system and method may be used in pools, spas, or other applications in which fluids are circulated through a fluid-containing vessel. The system includes a first pump that circulates fluid. A screen is coupled to the input of the first pump and acts to prevent debris from reaching the first pump. A second pump may be used to remove debris from the screen.
