OVERVIEW
AquaNaut’s 200 & 400 suction pool cleaners are designed with unique 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.

how do i stop the cleaner from turning on it's side?
A shopper on May 10, 2020
BEST ANSWER: You may have the suction set too strong and the cleaner is trying to climb the walls and falls back. Also the hose weights need to be on the first section of hose nearest the cleaner.
Is this compatible vinyl pools?
A shopper on Apr 5, 2020
BEST ANSWER: I think it probably is. The wheels rubber and there are no sharp edges to cut the vinyl
Does the Aquanaut 400 come with a hose?
Jen M on Feb 29, 2020
BEST ANSWER: Yes, my cleaner came with several sections of hose.

Spotless pool
This unit works off the suction of your pool, and yes it climbs the walls. Now the pool is spotless.

Hayward AquaNaut 400 4-Wheel Suction In Ground Cleaner
The AquaNaut 400 4-Wheel Suction In Ground Cleaner has worked fairly close to advertised performance. It runs slower than one might expect, but it does not tie itself up as did the previous Hayward pool vacs. Could be a little better at climbing sides of a plaster over gunnite pool, but none of our previous Hayward pool cleaners have been especially efficient at cleaning the sides. Although only a month in pool, it seems to be good at the random pattern cleaning. We have a kidney- shaped pool, which is difficult to clean. I have not watched the 400 to see if it explores both ends of the kidney, but it seems to be efficient at whatever it covers. We have a great amount of sand in our city and the wind is ever-present. So far, the 400 has cleaned it well. I suspect the sand will grind the internal workings as time passes. Not sure if there is any option to program or obtain a different cleaning pattern for kidney- shaped pools, but that would appeal to us. I clean my own pool because professional cleaning services just cannot sustain any degree of reliability or pride of workmanship. Thus, I am very interested in having a top tier cleaner. Would definitely recommend the AquaNaut 400 to picky folks who prefer a better quality cleaner.

AquaNaut 400 works great!
I upgrades my very old Hayward Navigator (lasted over 10 years) to this one. My old one occasionally got stuck, the AquaNaut does not have this problem and works great! I wasn't sure about setting the pressure to get the right number of revolutions but that was also easy and unless you have a clog at the filter its very consistent. So far I am extremely happy.

Great machine
This is by far the best pool vacuum I've ever owned. Was basically "plug & play" to install - took 5 minutes. Glad I bought it and I'd buy it again in a heartbeat!

cleans well. Gets stuck
I bought this on the advice of my cleaning pool company. It cleans very well but is always getting stuck on the drain. Pool company has done everything they can. It runs from 12am until 8am. Every time I get up ( 2am and 4 am ) it is stuck on the drain and I have to move it. I am thinking of going back to my old one that never got stuck.
