Poolmaster 27240 14 1/2" Pro Heavy-Duty Gunite Flex Vacuum with Deluxe Wheels. Poolmaster’s Premier Collection features high-quality materials with outstanding performance in mind for season-after-season use designed to keep your pool sparkling. For removing debris from gunite pools with hard-surface finish, you need a reliable flexible vacuum that can get the job done. The flexible body allows for easy contouring on the pool or spa floor. Deluxe nylon ball-bearing wheels prevent scratches and scuffs and produce a friction-resistant rolling motion for smooth performance. Swivel-function handle made from aluminum aids in smooth maneuverability. Six weights allows for vacuum to stay properly submerged. DO NOT use on vinyl liner pools. Can be used with any standard pool pole or vacuum hose – sold separately.
