About This Item

Hayward AquaNaut 400 Suction Side Cleaner able to clean pools up to 20' x 40' for all pool surface types.

Patented V-Flex™ variable vane turbine technology handles larger debris without clogging and maximizes suction power at virtually any flow, making them ideal for use with variable speed pumps.

The AquaNaut® Series of automatic suction pool cleaners were the first all-terrain, clog-eliminating suction cleaners on the market and they remain the best in their class. Available in two or four wheel drive models, AquaNaut is designed with patented technologies to deliver superior power, traction and balance for pools of different shapes, sizes, flow rates and debris types. They feature patented self-adjusting variable vanes known as V-Flex™ technology, which automatically adjust to allow for large debris to pass through the cleaner delivering maximum suction power at virtually any flow and providing a clog-free clean — covering pool floor, walls* and coves.
