Absolutely love it. I was hesitant at first because of the amount of negative reviews, but after making my own judgement and watching a few YouTube videos, I decided to buy one. I loved the fact that it runs off the return jet instead of the skimmer. What a bonus... You don't have to worry about missing skimming capabilities on your pool. The actual bottom bag doesn't "vacuum", but instead uses 2 jets of water that propel the bag around on the floor and push debris into the bag. The continual push from the Jets never lets the debris fall out of the bag. The Jets are also great at circulating the water on the bottom of the pool, and pushing chemicals around. Whatever silt that the bag doesn't pick up is pushed into water circulation that helps the regular filter skimmer remove it from your pool. It's like having swimmers constantly in your pool, stirring up any silt to be filtered. I previously had an aquabot, and payed almost double. The aquabot is so annoying to remove from the pool, and open the top, and pull the bags, and clean them. Trust me ..... It's obnoxious. The Aquabots suction is also limited to a 2 by 2 inch square area on the bottom of the robot, and is not as wide as the entire robot. You don't even have to pull this thing out of the water. Just grab it, pull the hanging hose, disconnect the bag, turn the bag upside down, rinse, reconnect. It's much easier. My pool has never been cleaner. I feel like some of the negative reviews come from people that may not have cut the hose to the proper length, or fail to check the filters in the device. You HAVE to cut BOTH hoses to fit your pool. Too long of a hose in the pool will certainly lead to a hose winding up. If you have a sand filter, then the metal filter at the end of the hose can get sand in it, slowing the speed of the unit down. Don't ever permanently remove the metal filter. It prevents sand from getting into a secondary filter. The secondary filter is inside the pump mechanism, that you can't get to without opening the Polaris case. I hear that if sand is in this filter, it can cause the Polaris to favor one side of the pool more than another, which can lead to coiling of the hose. Also, cracked housing in the pump inside the Polaris casing, or a bad seal of O-rings on the inside Polaris pump can cause it to favor one side, and end up coiling the hose. You can't expect mechanical things to work forever and not have any technical skills to fix or figure out how to maintain stuff. Chlorine is very tough on plastics and o-rings. I'll continue using a pool vacuum like this for as long as I have a pool. It's fantastic. One other great upside to this type of system is that no matter how much stuff you collect in the bag, it keeps going. Because.... The water that is sprayed into the bag and the water that pushes the Polaris unit around is not slowed down by the Polaris filter being clogged. It only loses pressure when your main sand or D.E. filter gets clogged and loses pressure. On the aquabot robots, after their filters are clogged, it starts moving at snail pace, and almost to a nonexistent move.... Very sad. One last cause of people having issues with the hose coiling, could be after they have cut the hose for the proper pool fit, that they didn't push the connector on the hose where it sits perfectly inside one of the Ring grooves of the hose, otherwise the hose won't turn freely inside the threaded adapter, causing it to bind up and eventually coil the hose. For reference....I have a 21 foot diameter pool. I had tons of bugs and debris at the bottom of my pool, that had accumulated for several months after my Aquabot died. Within just a few hours, the Polaris had cleaned the entire bottom perfectly. Within a day and a half, and adding some blue pool clarifier, the Jets on the sweeper helped stir up any silt on the bottom, and my pool is crystal clear now. No extra vacuuming from any other device. Only one brushing, to loosen sidewall dirt... Silt on the bottom of the pool is almost non existent. Give this item a shot.Bought this product in spring of 2022 because it was recommended by friend. Installation was very simple and vacuum does a good job. However there is a problem with the wheels. The front wheel fell off the first day we installed it. Found the screw in the vac basket and the wheel in the skimmer. Went to put it back together and it appears the screw is stripped and will not tighten. At that time also noticed other screws loose and when tightening them found another one stripped.Tried reaching out to the seller but was referred to call Polaris. Good luck trying to get help from that organization. I will figure out how to fix it on my own but would not recommend this product simply because I think it is poor quality.I believe everything in the design and function of the vacuum is good and rated it five stars on each category but gave it only three stars overall because of the poor quality.This is a great above ground pool cleaner , Unfortunately it will sometimes get caught on the ladder or curl up and only do part of the job . When it works it does a great job and it almost eliminates the need to vacuum!Was pretty simple to install, measure out the hoses (depth of pool plus 2 ft for the pickup hose, and 4ft shorter than the longest point away from where the trailer hose connects to pool outlet), then just drop it in the water and let it do it's thing. I like the fact that it doesn't use the suction side of the pool pump system, which would require to take out the pool skimmer basket, pre-charge the lines by filling them up with water, etc. This can be plugged into your system at any time and doesn't require any prep work besides turning the pool pump off before trying to screw the fitting into the outlet. Luckily, my pool outlet was a female inch and a half and I needed no adapters to get started. Just screwed in the trailer hose and that was all. I've only had it running for a day but it hasn't gotten hung up at all and seems to have gotten everything off the bottom of the pool so far and is a great cat entertainment device, lol.Since it moves around the pool very randomly and the filter basket flops around occasionally, it does take longer to clean the entire pool than manually hooking up a vacuum to a pole and manually sucking up dirt, but it also keeps dirt out of your pump's pre-filter since it uses it's own filter bag and doesn't connect to the suction side, as stated before. I like it, hopefully it lasts a long time.One fittings on the hose that screws onto the body was cracked totally in half I had to put a screw clamp to keep it in placeComplete garbage, if I could give it no stars I would, bought one for a second time because when it WAS working properly for a short time, it worked great, (thought maybe the first one was a lemon) but second time a failure again, the hose was cut to fit properly as well, tips on its side and dumps pool water right out of your pool, don't waste your money.This is my third. The only cleaner I could find that can sweep gum leaves. The cleaner can be troublesome but aren’t they all.
