Owning a pool is fun, but cleaning it is a pain. The Hayward PHS21CST AquaNut Suction Pool Vacuum is an automatic pool cleaner that is easy to install and use. It just might be what you’re looking for to clean your pool.

The AquaNut 200 features V-flex technology consisting of self-adjusting variable vanes that maximize the power. An adjustable roller skirt keeps suction constant even on uneven surfaces and obstacles. This Hayward pool vacuum comes with several pre-programmed steering sequences to cover your entire pool, and this pool cleaner is also ideal to use with variable speed pumps. With this pool cleaner, you can experience a complete clean.
Features
This pool cleaner has a 33’ hose and can clean a pool as big as 16’ x 32’. It can handle pool surfaces of concrete, gunite, fiberglass, vinyl, tile or pebble. It needs to be used with a pump size of at least ½ HP or 35 gpm. It turns every 8’ to 10’ and comes with a 2-year warranty, so you won’t have to worry if something goes wrong.
Roller Skirts
With innovative patented technologies and a robust design, the AquaNut 200 cleans your pool completely and reliably, no matter the terrain. It is designed to handle larger debris without clogging and to maneuver around obstacles such as drains. The adjustable roller skirt ensures it never loses suction. The clever design features quite possibly make this pool cleaner an excellent choice.
This pool cleaner is less likely than other models to get stuck on pebbles and other debris that fall into the pool. It rolls over drains without getting stuck. It can even clean the walls of a pool and the area where the walls meet the bottom, due to it robust tire treads that provide it with superior climbing power. The steering sequences are designed for it to cover both deep and shallow ends as well as walls. The features on this pool cleaner are clearly superior.

Leafs and other Debris
The AquaNut 200 is great for yards with lots of trees. It picks up things like leaves, nuts, and small twigs instead of just rolling over them. Nobody wants a pool cleaner uselessly clogged with leaves and other tree junk. If you have a yard with lots of trees, especially if they overhang your pool, this is probably a good pool cleaner for you.
This pool cleaner runs quietly, so you don’t have to worry about noisy pool cleaners anymore. It has three interchangeable throats that allow you to customize the suction based on your pool’s flow. The throats are very easy to change, so this is a great adjustable pool cleaner.
Drawbacks
Some users have complained about this pool cleaner being unable to climb out of the deep end, so if your pool has a deep end, you might want to consider that. The AquaNut 400 model is specifically designed for pools with deep ends, which might make it a better option.
There are mixed reports on the ability of the 200 model to climb walls – some say it climbs walls perfectly while others find that it tries to climb walls and then tips over. However, the majority of reports on this product are positive. If you use it and have issues with suction, you might want to try cleaning the pool filter.
