The Hayward AquaNaut 400 W3PHS41CST (also known as PHS21CST) is ideal for larger in-ground pools in virtually any shape or surface. The AquaNaut uses self-adjusting turbine vanes to ensure that it has maximum power at any flow rate to ensure it can suck up all sizes of debris, all the time. This system gives it the capability to easily suck up larger debris that other suction cleaners may miss.

The unique steering system has multiple pre-programmed internal steering sequences to ensure it can efficiently clean the pool. The steering sequence even reverses the left wheel every 11 to 14 feet of travel so the AquaNaut will move in another direction to ensure full pool coverage.

The wheels are large to allow the AquaNaut to climb over obstacles and maneuver easily - especially the main drains. The tread on the tires increases grip for climbing walls and other obstacles.
