Key benefits fineparticle capture: Removes fine sand (50200 microns), silt and clay (2050 microns), plaster dust, pollen, and algae spores to improve pool clarity. Leakproof seal: EPDM rubber sealing ring and integrated gasket prevent debris bypass for cleaner vacuuming. Durable construction: Triplelayer polyester mesh plus reinforced, doublestitched seams rated to handle over 50 lb of trapped debris. Reusable and easy to clean: Rinse with a hose after use and allow to dry to extend service life and reduce replacement frequency. Broad compatibility: Works with 8 or more Water Tech vacuum models (compatibility reference only).
