1. A fluid pumping system, comprising:
- a first pump for circulating fluid, the first pump having an input for receiving fluid;
a screen coupled to the input of the first pump, the screen for filtering fluid before the fluid reaches the input of the first pump and for preventing at least some debris present in the fluid from reaching the input of the first pump; and
a second pump coupled to the screen for removing debris from the screen.

Abstract
A system and method for reducing the collection of debris in a fluid pumping system. 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.
