Hayward AquaNaut 200 Automatic Pool Cleaner: V-Flex Turbine and 2-Wheel Drive for Average-Sized Inground Pools

The AquaNaut 200 uses your existing pump with no booster pump required. The patented V-Flex variable vane turbine self-adjusts to allow large debris passage while maintaining maximum suction power across a wide range of flows, making it well suited for variable-speed pumps. Two driven wheels generate positive traction on pool floors and walls, producing more consistent wall coverage than foot-seal suction cleaners on surfaces where the foot seal would otherwise degrade. Multiple pre-programmed internal steering sequences cover floors, walls, and coves. Three interchangeable throats allow further optimization for different pump sizes and speeds. Designed for pools up to 16 x 32 ft without a deep end.

AquaNaut 200 vs. AquaNaut 400: Choosing the Right Model

The AquaNaut 200 is designed for average-sized pools up to 16 x 32 ft without a deep end. The AquaNaut 400 handles larger pools up to 20 x 40 ft and pools with deep ends, where 4-wheel drive provides the extra traction and balance needed with the longer 40 ft hose. Both share V-Flex turbine technology, pre-programmed steering, robust tire treads, adjustable roller skirt, and three interchangeable throats. The 2-wheel version is the right choice for standard-sized pools; the 4-wheel earns its additional cost in larger pools and pools with deep ends.

Hayward AquaNaut 200 Frequently Asked Questions

What makes the AquaNaut 200 different from the Navigator Pro and PoolVac XL?

The Navigator Pro and PoolVac XL use a foot-seal design — the suction creates a partial vacuum that causes the cleaner to slide and redirect across the floor. The AquaNaut 200 drives two wheels that grip the pool surface and physically push the cleaner forward, producing more consistent traction on walls and across surfaces where the foot seal would otherwise degrade. The wheel-drive design also works more effectively with variable-speed pumps through the V-Flex turbine.

Does the AquaNaut 200 work with a variable-speed pump?

Yes. The V-Flex variable vane turbine is specifically designed to maximize suction power at virtually any flow rate. The three interchangeable throats allow further optimization for different pump speeds, making the AquaNaut 200 a strong choice for variable-speed pump installations.

Will the AquaNaut 200 climb pool walls?

The AquaNaut 200 is designed to cover floors, walls, and coves via pre-programmed steering sequences. Wall climbing capability may be affected by specific pool shapes and surfaces. Optional tape tires may improve performance on smoother fiberglass and tile surfaces.

The wheels are turning but the cleaner is not climbing the walls. What should I check?

Check suction flow first — insufficient suction is the most common cause. Confirm the pump is running at or above the 1/2 HP or 35 GPM minimum. Then inspect the wheel contact surfaces for wear; thinned or torn treads lose grip. Also check for hose kinks that restrict flow. If the pool surface is smooth fiberglass or tile, optional tape tires may help.

Is the AquaNaut 200 suitable for a vinyl liner pool?

Yes. The AquaNaut 200 is compatible with vinyl liner pools. Monitor contact pressure during the first few runs and dial back suction if the cleaner presses too hard against the liner on walls.
