Clean Your Pool Easily with the Hayward PHS21CST AquaNaut Suction Vacuum

Donald Foley: Keeps my pool very clean, better than everything else, most recently a Kreepy Krauly Sand Shark and a Polaris 360 pressure-side. Was advised to use the biggest of the 3 included water flow intakes because my pump can handle it, a Pentair Intelliflo 3HP. I get a ton of debris in my pool from trees giving the pool shade I’ve been told to cut down. Leaves and twigs and seed pods. I do everything myself but was considering hiring somebody to stop by the house regularly and help manage the debris before getting this vacuum.

The AquaNaut keeps the bottom very clean. It climbs the walls but the pool has a decent curvature between the bottom and walls. Also zero algae since my last drain/chlorine wash/fill, though I haven’t changed anything else I’m doing (BBB method with 1/2 gallon of 10% sodium hypochlorite liquid per evening in my 12,000 gallon pool keeping CYA 25-30 which is best for me I found). So maybe keeping the pool so clean with this vacuum is helping the algae control too.

Of course I run it with a leaf canister, and have the pump programmed to run at 3000RPM for 2 hours each morning for the main vacuum time then a slower rate for the rest of the day hours...

David BDavid B: I purchased this product based on the reviews here and elsewhere by users and also by the pool service professionals that have recommended this cleaner. The installation was simple, good instructions and not that complex. Set it up and had it cleaning the pool and climbing the walls in no time. This has not been without issues though.

First, the floats for the suction hose do not stay on, they fit poorly and do no completely circle the hose. They actually are a little to tight and partially collapse the hose (more on this later) and then come off later and you find them floating around the pool. This prevents the cleaner from climbing the walls and I found the cleaner lying on it's side yesterday in the bottom of the pool with both floats floating on the surface.

Second, one of the hose sections split at the connection point and it's useless, it allows air to be sucked into the hose. This may have been because I coiled the hose after the first time I used it, but there was nothing that said not to coil the hose and the troubleshooting guide actually tells you to leave the hose in the sun if you coil it and the loops won't come out. So I need a new section of suction...

RRACH: To say that we are satisfied with this cleaner is an understatement. We have always had a Kreepy Krauly, which was great, until we got our pool re-plastered. The two, flat, main drains at the bottom of the pool were replaced with the newer, safer, drains. Unfortunately, this meant two new drains that stuck up from the bottom of the pool. Suddenly, the Kreepy kept getting stuck. We were literally moving it about 10 times a day. We always liked the way it cleaned, but nobody wants to keep going outside and moving a pool cleaner. It defeats the purpose. In addition, the Kreepy Krauly tends to be a bit noisy. Thus, I started researching suction pool cleaners and came across this one. I was hesitant about purchasing due to the reviews about its inability to climb walls. Plus, I wasn’t sure it would not get stuck on the drains. I put off purchasing it for a year because the price was more than we wanted to pay. However, we realized it was a necessity. Honestly, it's actually one of the cheaper cleaners around. Plus, there is a rebate for this cleaner. Just search for Hayward Rebate Center on any search engine and you can find their rebate center. I have noticed there is almost always...
