Dolphin (2026 Model) Explorer E20 Automatic Robotic Pool Vacuum Cleaner, Wall Climbing, Active Scrubber Brush

I've owned a 30K gal pool for over 30 years, and have tried pretty much every pool cleaner out there from Kreepy to Barracuda to Hayward. The idea of a self-contained cleaner that bypasses your external pump and filter system is just genius. This item is quick, thorough, and flexible enough to handle light, quick cleans to heavy-duty post-rainstorm messes. No trouble handling anything from large tree leaves to microfine dust. I suggest ordering the basket with the accordion-style filtration to capture and collect fine dust particles. Runs randomly around the pool from the 12' deep end to the 4' shallow end and cleans the entire pool in 1-2 hours. It gets the sides and waterline as described. I would describe this unit as a pool cleaning system rather than just a pool vac. Set and forget. Turn it on a walk away. It is a substantial unit, especially when full of water, and I could see some smaller women struggling to pull it out of the pool to store. It simply does everything I need it to do well. The filter baskets remove and hose off easily and replace. My pool has never been this clean. Sorry I wasted $ on those other so-called "cleaners" for all those years. This unit easily makes them obsolete. Very impressive unit and technology.

It took no more than 15 minutes to remove from packing box and putting it in the pool to start cleaning. It climbs the smalls just as seen in the videos. It has a cycle on time that’s either 2 or 3 hours. Haven’t been around long enough while it’s running to time it. It reaches all corners of the pool. It’s a bit heavy when you take it out of the pool. After it drains then it lightens up. The latch on the bottom of the refuse basket maybe damaged. It’s easy to remove the basket to clean it. The filters captured a lot of fine dirt/particles that my Hayward Navigator wouldn’t pick up or if it did would go straight to the pool filter. Very happy with this product.

For eight seasons, I manually vacuumed our pool, and this little guy, whom we have named "Flipper," is unreal. The two-hour cycle cleans 100% of the pool, including the benches and stairs. He climbs the walls above the water line and everything in between. We have more debris in the shallow end, and I learned that the algorithm learns where to clean the most, so start it where you see the largest amount of debris in your pool. At first, we saw Flipper doing wheelies across the bottom. I did a little research, and the FAQ from the manufacturer's site stated to place the robot into the pool upside down, and it will right itself. It aids in removing excess air in the unit, and it worked like a charm. For the price, this little guy is a powerhouse.

Expensive, poorly designed, and zero support I’ve owned this robot pool vacuum for barely 1 year and 1 month, and it is now completely unusable. Almost immediately after purchasing, the cord began tangling constantly, requiring me to stop and untangle it multiple times during a single cleaning cycle. Extremely frustrating, but I dealt with it. About 4 months ago, the tracks started falling off. Again, I tried to make it work, I would put the tracks back on and restart the unit. Eventually, the problem got worse to the point where the tracks now fall off almost immediately. I even purchased a brand-new set of replacement tracks, thinking that would solve the issue. It didn’t. The tracks still come off, which tells me the issue is likely with the axles or wheels, parts that the manufacturer does not sell. I’ve tried researching replacement parts and reached out to the manufacturer directly. There is no phone number, only an online message form. I’ve submitted requests and received no response. For a product that costs nearly $700, this level of design failure and complete lack of customer support is unacceptable. Once their robots fail, you are essentially out of luck, no parts, no repairs, and no support. I’m posting this review to warn potential buyers to stay away from this brand. This was a major waste of money, and I strongly regret the purchase. I am also hoping that by posting this, the company will finally reach out and make things right, either by providing the necessary parts or allowing the unit to be sent in for repair. Until then, I cannot recommend this product to anyone.

The Good: this cleaner works great. It replaced my old Polaris and what an upgrade! I hadn’t cleaned my pool in a while. This cleaner picked all kinds of debris and silt. It climbs walls. Step climbing is more of a challenge (for any cleaner). It’s easy to clean the unit-which btw is v important. After multiple uses this summer, this unit is a keeper! So-so: the electric cord that fits into the control box did not seat well. The rubber end is v hard. However after a few weeks it did seat well and I was able to lock it in place. I contacted the company about this and they were willing to replace the unit or I could wait till end of pool season (fall). I won’t have to now. But that’s why I gave it 4 stars. Good value for money and would definitely buy again.

I have an 18'X36' inground pool with a vinyl liner. Power supply is about 15ft. from the pool and there is still enough cable to reach all areas of the pool without issue. It cleans most of the debris, but usually leaves a spot; however, it's not really an issue, it gets it the next day. Overall, this is a great value and exactly what I was looking for.

The best pool robot I have owned. I have always had the bug but this year decided to take the plunge. I do not need to waste money on wifi controlled or battery operated under powered cleaners. I have a 27’ pool and it is sparkling clean this year. Yes we did purchase. The better filter as others have recommended and it makes a huge difference. It never tangles, climbs up the sides and just cleans. I never leave it in the pool and remove it and place it in the garage after every use. The filters get emptied and debris removed, then rinsed and washed. I am very, very happy with this model and glad it was highly recommended to me by many reviews on the web and our local pool supplier that had none in stock.

I didn't find a lot of reviews and only saw a couple of youtube videos of it operating in an above ground pool so I was a little skeptical at first. It works fantastic and climbs the walls to do the waterline perfectly. It has enough suction to climb the wall and come back over on itself without falling off. I was very impressed. Super easy to operate and clean out. I would suggest adding an ultrafine filter to your order for the fine sand and algae that may creep in. The filters are standard for a few different units and made by a couple different manufacturers so you can find one for around $100. Altogether, best thing I've bought for our pool. 18'x33'x52" pool for reference.

This is a good little vacuum with a nice basket system that's easy to clean and take in and out. My only real complaint is that it doesn't handle stairs at all. It does a good job on the bottom and the sides up to the water line, but it will not go up any stairs. My stairs are very wide as well as the picture shows. My old Nautilus CC Plus vacuum easily cleaned the stairs but not this model. Still recommend it though.

Got the Dolphin E20 after my previous pool cleaner stopped working and based on a recommendation from my neighbour. I had been expensing loads of energy and wasted time dragging the hose around for a couple months to vacuum my pool. This unit was truly the best investment I made since deciding to put in my pool. Cleans the pool thoroughly, including the side walls up to the water’s edge within 3hrs which allows me time to do other things. Easy to clean and stow. My only disappointment is the Bluetooth capabilities and mobile app have limited features, are not the greatest and don’t work very well. You have to be 3 feet max away from the unit with your phone for the app to connect to the Robot and when it does some of the features don’t work.

While this product is “pool ready”, my completely normal small/medium size pool was a challenge for this robot to map and clean. It focuses all its time in one quadrant area and the walls, while the floor remains littered with leaves. Very unsatisfied and their return policy is a pain so pretty much stuck with it.
