The PoolVac Ultra™ by Hayward is a truly smarter cleaner. Employing our exclusive Aquapilot™ programmed steering, Pool Vac Ultra systematically attacks every square inch of your swimming pool. Cleaning it faster and far more effectively than the random-pattern movements of unintelligent automatic pool vacuums. With advanced features like a specially designed intake to vacuum microscopic dust and pollen to larger debris, and with no debris bag to empty, the Poolvac Ultra equals years of trouble free operation.
