Equipped with patented SmartDrive® technology, Hayward Navigator Pro Suction Cleaner systematically travels the floor, walls and coves of in-ground gunite pools up to 20 x 40 ft., creating thorough, reliable results—and with "shoes" designed for gunite surfaces and enhanced maneuverability, it keeps moving until the job is done. By connecting directly to your pool's filtration system and installing in less than 10 minutes, Navigator Pro provides unwavering suction and simple setup. Plus, its wide vacuum inlet and unique wing design create a broad suction path that dirt and debris can't escape. Navigator Pro also eliminates the need to empty debris bags, reducing overall maintenance and increasing relaxation time, while its advanced design cleans quietly and efficiently for a more peaceful backyard environment
