HWD White Gunite Pool Vac Ultra Automatic Pool Cleaner Hayward sets the standard for high performance cleaners and now we are doing it again with the Pool Vac Ultra. The Pool Vac Ultra automatic cleaner features new product enhancements such as wide, longer wearing wings, plus a 2-year warranty. The Pool Vac Ultra features our exclusive AquaPilot® programmed steering which assures that virtually all pools will be cleaned in under 3 - 4 hours. Quiet, attractive and efficient, the Pool Vac Ultra will provide years of satisfying performance. Why is AquaPilot programmed steering better? Hayward's exclusive technology harnesses the flow of water through the filtration system to drive the Pool Vac Ultra in an alternating series of right and left-hand turns to systematically clean pool surfaces and ensure the best coverage and most efficient cleaning path. It cleans faster and better than random-style cleaners and reduces the possibility of missed or over-visited zones in the pool. Features Longer wearing components (wings, flaps and shoes) for additional product longevity Exclusive AquaPilot programmed steering pattern ensures the entire pool is cleaned quickly and completely Unique turbine/gearing system provides constant balanced water flow assuring quiet operation and gentle movement across the pool bottom Wide side wings increase speed of pool coverage by 10% Installs in less than 10 minutes, without tools
