The Tiger Shark pool cleaner uses pleated filter cartridges to trap debris and filter the water moving through the robotic pool cleaner. This is a bit of departure from other robot pool cleaners, which use a filter bag to catch the debris.
Cleaning your filter cartridges regularly can help to extend their life. The best time to clean these cartridges is after the cleaner has run it's cycle. Acidic debris, chemicals and live bugs can damage the polyester material, if you allow the cleaner cartridges to sit dirty for very long.
Tiger Shark filter cartridges are subject to a similar replacement schedule as pool filter cartridges. Generally, replace Tiger Shark cartridges after 2-3 seasons, or if the fabric breaks away from the edges, or develops holes.
