Hayward AquaNaut 400 Automatic Suction Pool Cleaner

The AquaNaut Series of automatic suction cleaners are designed with patented technologies to deliver a thorough and reliable clean for pools of different shapes, sizes, flow rates and debris types. Available in two or four wheel drive models, AquaNaut features patented self-adjusting variable vanes known as V-Flex technology. Because the variable vanes automatically adjust to allow for large debris to pass through the cleaner, V-Flex technology delivers maximum power even at lower flow and provides the peace of mind of clog-free cleaning, covering pool floor, walls and coves.

Experience the most complete clean with AquaNaut 400 suction pool cleaner from Hayward. AquaNaut features patented self-adjusting variable vanes, known as V-Flex technology, that maximize power at almost any flow and allow for easy passage of large debris. Multiple pre-programmed internal steering sequences ensure that the cleaner covers both deep and shallow ends equally, including walls. No matter the pool surface, the AquaNaut 400 maneuvers with patented robust tires and an adjustable roller skirt that maintains optimal suction, even when encountering obstacles. Service and maintenance is simple; better still, you’ll rest assured knowing that your AquaNaut 400’s durable design is backed by Hayward’s network of reliable service centers.

The patented self-adjusting variable vanes of AquaNaut’s V-Flex technology provide maximum power at almost any flow (perfect for use with variable-speed pumps) while virtually eliminating clogs. Because the variable vanes adjust automatically, they allow even large debris to pass easily through the cleaner, resulting in complete peace of mind. The Patented robust tire treads provide superior climbing power on any surface and skillfully maneuver around obstacles such as main drains.
