Dolphin (2025 Model) Explorer E20 Automatic Robotic Pool Vacuum Cleaner, Wall Climbing, Active Scrubber Brush, Ideal for In-Ground Pool up to 33 FT in Length

This is an excellent pool cleaner. It is really well designed, sturdy construction, and has done a great job cleaning the bottom of my above-ground pool. I used it all last season and have started to use it for the 2025 pool season. It made short work of cleaning some winter debris from the bottom (pool was covered but some leaves still got in). Recently we had a severe hail storm and a lot of leaves and unripe wild cherries fell into the pool from the nearby tree. The first run of this cleaner completely filled its basket with the cherries and leaves. It took 3 runs to clear the bottom but then the pool was clear again.I love that I can put this in and let it run and it'll move all over the bottom of the pool and collect the dirt and debris into its basket. The basket has a latched bottom, so it is easy to empty and rinse out with a garden hose.My only complaint is the ring of blue LEDs that circle the power button are blindingly bright. They need to be turned down!! They also stay on after the cleaner has timed out and stopped, which makes no sense. I put the controller in our pool deck box just so the blue light isn't shining all night after it finishes running.Highly recommended pool cleaner!

We had a Dolphin in a past home and sold it when we moved since our new home had no pool. We just purchased a new home with a pool that came with an Aiper robot, and we absolutely hated it, so we purchased another Dolphin. Unlike the Aiper, the Dolphin is corded, but that makes for easy retrieval at the end of cycle. The Dolphin also does not get stuck like the Aiper did. The Dolphin Is very easy to clean out (again, unlike the Aiper), and has simple controls. This one seems similarly built to our old one, which was super sturdy and lasted in the Arizona sun. Dolphin is great!

I live in a "cottage community" named Kingwood, TX, just outside of Houston. I don't expect that to mean much to the average Amazon shopper, but it's important to note that Kingwood is marketed as "The Livable Forest". When it was being developed in the 60's, 70's, and 80's, great care was taken to preserve the trees in what had once been timberland owned by paper and wood companies. The foliage is very dense. There is no place in my yard or time of year when pine needles and leaves aren't constantly falling. We even have a sweetgum tree that drops little gumball-sized pinecones that are worse to step on than lego, especially barefoot, like you would be while swimming. Our pool is under constant assault. Raking every day was a hopeless exercise in futility. We bought a battery-operated "leaf blaster" that attaches to the end of a pole and vacuums the leaves into a net bag. When gumballs weren't jamming the impeller, it was such a huge job to vacuum that the kids and I would take turns working and still be too tired to play in the pool when we finished the endeavor.Worse, if the pool started to get algae, we couldn't see the bottom to clean out the debris. We would treat/shock/filter out the algae and discover a layer of leaves at the bottom, still covered in algae that would re-infest the pool as soon as they were stirred up by a rake or the leaf blaster, leaving us blind to continue removing them, and the maddening vicious cycle would continue. It's a 27' pool with two pump inlets, so adding skimmers to those helped catch a LOT of the leaves and debris before it sank to the bottom, but the skimmers can't catch everything and the cycle continued.I asked a few neighbors, did a lot of online research, and sifted through hundreds of pool cleaning options (just watch what happens to your facebook timeline after you've googled it a few times). A highly-trusted colleague and friend bragged on and on about her Dolphin robot and the reviews were good, so I got hung up between the E10 and the more expensive Escape. The Escape purports to be able to climb walls and have better mapping of the pool surface (plus wifi/app controls, IIRC). I decided to save myself $200 and go with the cheaper E10.NO REGRETS! It doesn't matter if the water is clear or not. Just drop it in, turn it on, and walk away. Come back in an hour, empty the basket, and start it again. Lather, rinse, repeat until the basket comes out clean. It picks up leaves, pine needles, GUMBALLS, and even small sticks! If algae rears its ugly head, we can be confident that there is no debris left on the floor of the pool before kicking it with only one treatment and shock.It's not supposed to be able to climb walls, but it does occasionally go up the wall to the water line before backing back down. Reviewers complaining about it doing wheelies don't seem to understand how it works. This is how it reorients itself to change directions.An external bag instead of a filter basket would be nice so that I could add a bigger one, but then the filtration might not be as good. This isn't much of a shortcoming, because the basket is extremely easy to remove and hose out. The screens can even be popped out of it for more thorough cleaning.The power supply did fail on ours less than a year after we bought it but Maytronics, for their part, was great. They had me email some photos of the failing unit's behavior, asked a few simple questions, then sent me a new one without even asking that I return the old one (I'm a pretty technical guy, so I may try to fix it as a spare, should the new one die after the warranty expires).I REALLY wish the wire had a swivel joint on the robot (it does swivel at the power supply, sort of). After a couple of cycles, the wire will be hopelessly wound up and tangled. It's not too much of a hassle to disconnect it from the power supply and untangle it, but it shouldn't be necessary. Some users have reported good results by putting foam pool noodles over the wire to prevent it from tangling. I may try that.All in all, we have a huge above-ground pool in a notoriously hot environment with lots of trees. It's a perfect storm of conditions that can turn pool ownership into a nightmare. This robot changed our lives and was worth the expense.

My last dolphin died a few days before our sons bday party. Followed the online guides and tested the components. The motor had gone out. Got this one in 2 days and the pool was clean and ready to go for the party. I like this one better than my last as the cord is much shorter ( our pool is very small) and it doesn't seem to get tangled like the other one did. I hate how expensive these are but man it is such a game changer if you have a pool.

I ad purchased a smaller hand vacuum for the pool when my robot decided to not work this season. I used it for 2 days and realized spending the money on a robot is well worth it. I love this robot. Yes it has a cord but I want to throw it in the water and forget it. The cordless only run so long and then need charged. After heavy rain I can’t wait around for it to charge. The basket is so easy to remove and clean and this was one of the more reasonable priced items. I love it!!
