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.\u003c\/p\u003e\n\n  \u003ch2\u003eAquaNaut 200 vs. AquaNaut 400: Choosing the Right Model\u003c\/h2\u003e\n  \u003cp\u003eThe 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.\u003c\/p\u003e\n\n  \u003ch2\u003eHayward AquaNaut 200 Suction Pool Cleaner Specifications\u003c\/h2\u003e\n  \u003cdiv class=\"spec-list\"\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eSKU\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003eW3PHS21CST\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eCleaner Type\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003e2-wheel drive suction-side automatic pool cleaner\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003ePool Size\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003eUp to 16 x 32 ft without a deep end\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eDrive System\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003e2-wheel drive; wheels powered by V-Flex turbine\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eTurbine\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003ePatented V-Flex variable vane; self-adjusting for large debris passage; maximum power at virtually any flow\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eSteering\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003eMultiple pre-programmed internal steering sequences; turns every 8 to 10 ft; covers floors, walls, and coves\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eTraction\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003ePatented robust tire treads; superior climbing power and obstacle maneuverability\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eRoller Skirt\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003ePatented adjustable roller skirt; maintains optimal suction on uneven surfaces\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eThroats\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003e3 interchangeable throats for variable-speed pump compatibility and debris passage optimization\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003ePower Source\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003eExisting pool pump; no booster pump required\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eMinimum Pump Size\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003e1\/2 HP or 35 GPM\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eConnection Point\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003eDedicated suction port or skimmer\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eIncluded Hose\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003e33 ft\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eCompatible Surfaces\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003eConcrete, gunite, vinyl, fiberglass, tile, pebble (optional tape tires may be required for smoother surfaces)\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eWall Climbing Note\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003eWall climbing capability may be affected by specific pool shapes and surfaces\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eDebris Handling\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003ePasses directly to pump basket and filter; no onboard bag required\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"spec-row\"\u003e\n\u003cdiv class=\"spec-key\"\u003eWarranty\u003c\/div\u003e\n\u003cdiv class=\"spec-val\"\u003e2-year limited warranty (parts)\u003c\/div\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eHayward AquaNaut 200 Frequently Asked Questions\u003c\/h2\u003e\n\n  \u003ch3\u003eWhat makes the AquaNaut 200 different from the Navigator Pro and PoolVac XL?\u003c\/h3\u003e\n  \u003cp\u003eThe 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.\u003c\/p\u003e\n\n  \u003ch3\u003eDoes the AquaNaut 200 work with a variable-speed pump?\u003c\/h3\u003e\n  \u003cp\u003eYes. 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.\u003c\/p\u003e\n\n  \u003ch3\u003eWill the AquaNaut 200 climb pool walls?\u003c\/h3\u003e\n  \u003cp\u003eThe 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.\u003c\/p\u003e\n\n  \u003ch3\u003eThe wheels are turning but the cleaner is not climbing the walls. What should I check?\u003c\/h3\u003e\n  \u003cp\u003eCheck 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.\u003c\/p\u003e\n\n  \u003ch3\u003eIs the AquaNaut 200 suitable for a vinyl liner pool?\u003c\/h3\u003e\n  \u003cp\u003eYes. 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.\u003c\/p\u003e\n\n  \u003cdiv class=\"doc-links\" role=\"complementary\" aria-label=\"Hayward AquaNaut 200 2-Wheel Drive Suction Pool Cleaner Manual and Warranty Info\"\u003e\n    \u003ch2\u003eHayward AquaNaut 200 2-Wheel Drive Suction Pool Cleaner Manual and Warranty Info\u003c\/h2\u003e\n    \u003cul\u003e\n      \u003cli\u003e\u003ca href=\"\/docs\/hayward-aquanaut-200-owners-manual.pdf\" target=\"_blank\" rel=\"noopener\"\u003eOwner's Manual \u0026amp; Installation Guide (PDF)\u003c\/a\u003e\u003c\/li\u003e\n      \u003cli\u003e\u003ca href=\"\/docs\/hayward-aquanaut-200-flow-adjustment-setup-guide.pdf\" target=\"_blank\" rel=\"noopener\"\u003eThroat Selection \u0026amp; Hose Configuration Setup Guide (PDF)\u003c\/a\u003e\u003c\/li\u003e\n      \u003cli\u003e\u003ca href=\"\/docs\/hayward-aquanaut-200-parts-diagram.pdf\" target=\"_blank\" rel=\"noopener\"\u003eIllustrated Parts Diagram \u0026amp; Wheel Drive Replacement Reference (PDF)\u003c\/a\u003e\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\n  \u003cscript type=\"application\/ld+json\"\u003e\n  {\n    \"@context\": \"https:\/\/schema.org\/\",\n    \"@type\": \"Product\",\n    \"name\": \"Hayward AquaNaut 200 2-Wheel Drive Suction Pool Cleaner\",\n    \"brand\": { \"@type\": \"Brand\", \"name\": \"Hayward\" },\n    \"model\": \"AquaNaut 200\",\n    \"description\": \"2-wheel drive suction automatic pool cleaner for inground pools up to 16 x 32 ft without a deep end.
