Dolphin Quantum Robotic Pool Cleaner (2025 Model) — Oversized Ultra-Fine and Standard Filter Bin, Weekly Timer, Anti-Tangle Swivel, & Waterline Cleaning for In-Ground Swimming Pools up to 50ft

The media could not be loaded. Honest review, not sponsored, etc: this is our best robot yet!The house we purchased 12 years ago, came with a large in ground pool. We're also surrounded by pine trees, birches, maples, oaks, ... . Cleaning manually with a suction hose, wasting so much time, water and chemicals was not an option for me. Thus started the path with robotic cleaners. One particular brand we had 4 failures between motors and control boxes in 10 years; one dolphin robot would not climb walls, another one died and last year, in 2021, we actually ended up with TWO robots. An aquabot ( only really cleans floors despite saying it does walls ) and this mid range Dolphin Quantum.This Dolphin Quantum is hands down our best robot yet.I does not have all the bells and whistles, like remote control, wifi, fancy display ... but forget all that crap. Had it. Doesn't work ... or the robot dies and then you wasted an extra $250 $500 on fancy features you barely use.This robot ticks all the boxes for me:+ extra large volume cleaning basket+ two large soft scrubbing brushes (many others just have 1)+ basket is easy to install, remove, open and clean out+ no bags to clean for 5 - 10 minutes, that may blow off their tray (smart pool brand robots issue) ... just a simple sturdy rigid box with a full bottom that opens up+ dead simple control box: power and pick 1 2 or 3 (for repeat cycle in n days)+ cleans the floor, inside corners between floor and walls as well as the vertical walls+ does a fabulous job cleaning around the water line and even moves sideways across the waterline (see video clip)+ swivel cord = YES (see photo, video and note below)+ has not gotten stuck on our steps into the pool+ has not gotten stuck on our floor drain+ fine and ultra fine filters are super easy to swap outIgnore the review for this robot that says there's no swivel. The white thing in that customer's picture is the swivel! As advertised. Don't know how they missed it. It works and is quite standard across the industry.Now there's a trick to having the swivel work for you - which I learned the hard way with our previous brand robot that we had 4 of, and they were notorious for tangling:>>> only give the robot as much cord as it needs!Put the robot in the water with next to no cord, get the whole cord stretched out on the deck, leave excess cord on the deck, and tuck away whatever amount of cord it does not need, then plug it in.If you have a 15x30 20x40 pool and chuck the robot in with all the cord, it may / will tangle. However if you have a 40 ft long pool and and you give it about 45-50 feet, it will untangle and swivel when it goes across to the deep end on other side of the pool.Has ours tangled in the past year? Minimally so. Sometimes, they just want to run in a circle a bit after they've taken a lot of cord into the pool, and in a year's time, two summer seasons, it's had a few minor issues with the cord. But no cord was tightly damaged and Nothing like when you don't have a swivel or when you give it unlimited cord.This thing has been a beast, with the standard (non pleated) filter, filling up its basket with leaves, seeds, ... it does a solid job on walls with its two scrubbers against algae, it comes up out of the water with the front and then scrubs the wall sideways for a bit. Absolutely fabulous.Now this year, we did end up with some water quality issues and excess algae. After fixing the water for phosphates, instead of doing the vacuuming with a suction brush on waste as they said at the pool store ... don't use a robot, you must hand vacuum to waste ... it was taking way too much time. So, I figured I'd let the robot do it anyhow. I swapped in the extra fine pleated filters and sent the robot on its way. And it was doing great! It sucks up the phosphate that fell to the bottom overnight easy peasy. Within two days, some backwashing, the robot running around, sucking up the dropped material on the floor, our pool is looking a ton better and should be back to pristine condition in a couple days.This is not an inexpensive robot, you can buy a lot cheaper, but for our in ground vinyl pool, with a lot of floor and surface area, tons of cleanup in the fall; it is a very solid performer and gets my two thumbs up.

Summary:- randomly stops running, sometimes only a few minutes after starting. 11 months of use and only runs for less than one minute. It is now basically completely useless- line twists and keeps vacuum from going all around the pool- scrubbing mechanism is not good enough to not have to scrub manually- When the line isn't tangled and the vacuum decides to run for more than an hour, it did do a good job cleaning leaves. But those two things happening at the same time was rare.The biggest problem is that the dang thing turns off early very frequently. I started noticing it a few months after I bought it, but didn't think anything of it. I thought it might have a shutoff after it senses it cleaned the whole pool. It kept on getting worse, until now it will only be on for less than a minute. So it is essentially a piece of garbage, very expensive garbage. I have reached out to customer service and am waiting for a response. Hopefully the customer service can fix it for free, I would really love to just get my money back, but I doubt that is going to happen. Even if they do fix it, it is still quite an inconvenience that you would expect from a much cheaper product.The 'anti-tangle technology' is a fabrication. From day one the hose has been tangling. My whole pool can basically never get cleaned because the line twists and the vacuum doesn't have enough strength to pull it out. I read online that you can stretch it out and leave it in the sun and it will lose the twist. I did that, and it worked for one day before it was twisted again. So I guess I'd have to do that every single day for it to clean better. At this point, just using a traditional pool cleaner that plugs into the wall sound about 1000 times easier.The scrubbing kind of works. It isn't a substitute for you doing it yourself though, which was a major disappointment. You have to scrub less frequently, but make no mistake, you'll have to be out there scrubbing at some point, for sure.I would 100% recommend not getting this. A poolside cleaner for half the price you make you twice as happy. I'm living with a lot of regret right now.

Replaced my dolphin triton after nearly three years with the Quantum. It is working like a champ so far. Does a great job. Pretty expensive at $1300, but compared to hiring a pool company it is a bargain. I hope it lasts longer than my Triton . It lasted under 3 years. Still,I wouldn’t have a pool without one of these. They make my life so much easier.
