    • Very effective
Style: 2-Wheel
Absolutely blown away by this thing. I’ve have a g3 barracuda I’ve been using for 10yrs now. It did a decent job and was way better than vacuuming manually. I left it in the pool 24/7 and depending on the time of year had it running several hrs a day. Pool would be decent but struggled with leaves and pine needles especially in fall and winter here in FL. Over the last 10yrs the trees behind my property line have grown and throw way more leaves and pine needles in my pool every year and the barracuda struggles more and more, constantly getting clogged and not working. Got my aquanaut 2 days ago hooked it up, dialed it in as close as I could to the correct rpm. This thing is a beast just sucking up everything within a few hours it had my filthy pool almost spotless. I have a zodiac leaf canister hooked up as well and had to dump it 4-5 times as well as the cleaner got jammed up with debris a few times in the hrs it ran. While the cleaner did get clogged I don’t fault the cleaner as my pool was an absolute mess with leaves, pine needles, bark and some small sticks, that is beyond anything the aquanaut is advertised to do and directions say to clean out large debris prior to using the aquanaut. No that the pool is clean I have no doubt it will run flawlessly without getting clogged. I did have to run my Hayward variable speed pump almost 300rpm higher to achieve the correct rpm on the aquanaut. At first I’d did not like this as it pulls almost 200w more power but from the looks of it I will be able to drastically cut down the hrs of cleaner time. I was running my barracuda cleaner 4hrs a day and looks like I will be able to run the aquanaut under 2hrs which will save a few $ over the yrs of use. One thing I wish I had researched was the big difference between the 2 wheel vs 4 wheel version being the 4 wheel does longer straight aways before turning aka for larger pools. I thought the 4 wheels was more for climbing and traction from deep end to shallow. Again not the cleaners vault it’s mine but the good news is they make the gear to gain that ability for the 2 wheel and it’s on like $13. ... show more

    • lookd nice does not clean.
Style: 4-Wheel
This unit does not clean your pool. Never climbs the sides will go around a curve in your pool wall. will not pick up debris. The smallest leave will clog the intake and it will just stop moving. I have a variable speed pump and it does not work It is one of the most expensive non functionalable cleaners available. I should have read the reviews as they are 90% negative. I want to get rid and recieve a better unit but not from Hayward. There is no tech support. They do not have a clue and will send you to a dealer who will say you did not buy it from us! Shame on Hayward. ... show more

    • Spend the extra money over a cordless one
Style: 4-Wheel
I bought one of those rechargeable cordless ones for half the price a week before I got this one. Over 3 days time, I ran it 5 cycles for the for the 40 minutes that it would operate on a 6 hour charge. The pool didn't look any different. I sent it back and got this one for another 200 bucks. I dropped it in the pool and left it there for 24 hours or so, doing nothing more than emptying the skimmer basket a couple of times to clear out all the leaves that it gathered. The pool looks like I just installed it today. Better still, the hose that they sent was was just barely long enough to cover my 40' pool and and caused the vacuum to tip and be less effective at the end of its reach. I wrote Hayward about the problem and they said they would send me more hose. I expected them to send me a single additional length of hose (about 3') which would have solved the problem. Just 2 days later an entire Box of 10 brand new hose sections arrived, with with no hassle or cost to me whatsoever. I am very impressed with the product and the customer service. Running for 24 hours completely unattended, the machine never got stuck once. When you get it, READ the instructions. It's very tunable to meet your needs. It can climb the walls, or be tuned down so as to only do the bottom (which is how I have mine set up). There are 3 different restrictor plates that can be swapped into the cleaner to change how fast it goes, as well as a valve at the skimmer/intake connection to control the suction. It's still new, so I can't speak to longevity, but it's initial mission blew the contender out of the water (bad pun intended). ... show more

    • Works great
Style: 2-Wheel
This pool vacuum was cheaper by hundreds than the upgrade suggested by my pool comtractor- this one came recommended by my pool guy. It comes with everything you need so don't order the extra hoses or "bought together" items. It works well and is easy to use, my 9 year old is able to disconnect and reconnect when we have company in the pool. It is durable and captures my whole pool in its pattern of movement. ... show more

    • Hayward vacuums are the way to go!
Style: 2-Wheel
Hayward vacuums for the pool are the best! We’ve owned many pool vacuums but Hayward vacuums are the best. Our last one just stopped working but lasted us 5 good years and so we just purchased this one to replace. So far so good! Very happy! And worth the money don’t go cheap with a pool vacuum!
