The Hayward Navigator sets the standard in high-performance cleaning for in-ground pools of all types and sizes. Simple to install, Navigator features the exclusive SmartDriveŽ programmed steering which assures that the average pool will be cleaned in less than 3 - 4 hours. Quiet and attractive, Navigator is the intelligent choice in automatic cleaners for smart pool professionals everywhere. Why is SmartDrive programmed steering better? Hayward's exclusive technology harnesses the flow of water through the filtration system to drive the Navigator 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.
