Hayward AquaNaut 400 4-Wheel Suction Cleaner, W3PHS41CST

The Hayward AquaNaut 400 is a four wheel drive suction side pool cleaner that ships with 40 ft of hose and cleans pools of any shape up to 20 x 40 ft. It runs off your existing circulation pump and works on concrete, gunite, vinyl, fiberglass, tile and pebble.

V-Flex: power at any flow

The throat of the cleaner has patented self adjusting variable vanes. They open to pass leaves and other large debris that would jam a fixed throat, and they hold cleaning power steady across almost any flow rate, so the cleaner keeps working whether the pump is on high or low speed.

Covers the whole pool

Multiple pre-programmed internal steering sequences move the cleaner through the deep end, the shallow end and up the walls in turn, so no one area gets all the attention. Four wheel drive gives it the traction to climb and to get over drains and fittings.

Simple to live with

There is no booster pump and no power supply to install; it plugs into the skimmer or a dedicated suction line. Service and maintenance are straightforward. If you want the same cleaning in a two wheel drive unit, the AquaNaut 200 is the companion model.
