Hayward RC9740WCCUB SharkVac Robotic Pool Cleaner, X-Large, Blue/Black/Grey

Uses smart steering technology that provides an efficient cleaning pattern, scouring the floor, walls, coves and waterline Runs separately from the pool's filtration system reducing the frequency of filter backwash cycles No extra hoses, hookups or pumps required. 2 fine porosity filter elements - just remove and rinse with garden hose, no need to turn cleaner over to empty Top-access cartridge filter allows quick debris removal and easy cleanup Out-of-water and beach-entry sensors stop SharkVac XL from running out of the water while cleaning the waterline, protecting the motor and extending cleaner life. Beach-entry sensor reverses direction when pool cleaner starts climbing out of the water
