Product Description

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.

AquaNaut 200 is a 2-wheel drive model designed for pools up to 16’ x 32’. AquaNaut 400 is a 4-wheel drive model designed for larger pools and pools with deep ends up to 20’ x 40’.

  • Patented V-Flex™ variable vane turbine technology eliminates clogs and maximizes power at almost any flow.
  • Perfect for use with variable-speed pool pumps.

Maintains constant suction

  • Patented adjustable roller skirt maintains optimal suction on uneven surfaces.

End-to-end cleaning

  • Multiple pre-programmed steering sequences ensure complete pool coverage.

Optimal suction at almost any flow.

  • Three easily interchangeable throats improve debris passage and suction performance, making it ideal for use variable-speed pool pumps.

Bought it 1 1/2 years ago. about 2 months ago, took it to dealer. was running around in circles at bottom of pool. He supposedly fixed it. Now it's doing the same thing. What do I do now. It should still be under warranty. Dealer said he broke one of the wheels when he tried to remove it. Don't know ifhe installed a new wheel.

Larry, if the Hayward Pool Products Hayward AquaNaut 200 Suction Pool Cleaner still has a warranty on it I would suggest getting the cleaner repaired that way. All warranties would be processed directly through the manufacturer. Hayward can be reached by calling 800.429.9273, I suggest calling them to process this warranty.

May the Aquanaut 200 be used on a 15x30 concrete inground pool that has a variable grade depth, from 4 ft to 8 ft? or only for shallow pools?

A  Answered on 3/24/2019 by InyoPools Product Specialist Lennox H.

Hi, Ivan. The AquaNaut 200 is too small of a cleaner for your size pool, you will need to use the AquaNaut 400 or 450 model.
