New Hayward Robotic Pool Cleaner, AquaVac 500. This cleaner comes with a microprocessor-based program that determines the most efficient cleaning route, using up to 94% less energy. The AquaVac Hayward robotic cleaner is equipped with dual-mode technology which makes it possible to choose from two cleaning programs: 90 min bottom only, or 3-hour bottom, wall and waterline cleaning. Cleaning out the internal filter is easy with a top-access debris container & removable cartridge elements. The Hayward AquaVac 500 features a sleek, modern, low-profile design with wheels that navigate raised main drain covers easily. Integrated recurring timer allows you to choose cleaning frequencies every 24, 48 or 72 hours. Dual-scrubbing brushes loosen dirt, debris and algae. 60’ swivel cord minimizes tangling. An out-of-water sensor prevents the AquaVac Hayward robotic cleaner from running out of the water.
