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.

End-to-end cleaning

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.
