Abstract: A filter system for filtering and collecting debris from a swimming pool is installed in the well along the sides of the pool. The system has a debris collector element in the form of a screen basket. A skimmer or weir element is in the form of a tube. The bottom end of this tube is connected to the top end of the collector basket. The top end of the tube receives water and debris when the water level in the well is low. The weir has a channel running completely therearound formed in its upper portion. When the water level in the well is low, the skimmer floats down to a position low enough to permit water and debris to pass therethrough into the basket. When the water level in the well is high, water enters the weir channel and drives the weir upwardly blocking the feeding of water and debris contained therein from the basket back into the well.
