Hayward Pool Products has expanded its line of automatic pool cleaning products with the introduction of the AquaNaut® 200 and AquaNaut®400. Available in two- or four-wheel drive models to accommodate any pool size or shape, the cleaners use self-adjusting turbine vanes to ensure maximum power at almost any flow. The cleaners’ adjustable roller skirts and robust tire treads work in concert multiple preprogrammed steering sequences to create enhanced climbing ability and obstacle maneuverability. The AquaNaut 200 travels 2.4 to 3 m (8 to 10 ft) before turning and comes with a 10-m (33-ft) hose. The AquaNaut 400, which is intended for larger pools, travels 3.3 to 4.2 m (11 to 14 ft) before turning, and is equipped with 12.2-m (40-ft) hose.
