Optimized Pool Circulation and Debris Removal: The Patented Cyclone is designed for 6" skimmer baskets in above-ground pools, boosting water flow and creating powerful suction. It efficiently draws in leaves, bugs, and debris, making pool maintenance quicker and easier. (Note: Performance may vary based on pump horsepower, speed, and distance. For best results, clean filters before use and use the included weir wedge to prop open the weir door.)
