Without these Gen 2 filters, the Explorer E20 cannot clean smaller particles, such as algae, sand, and other debris.
Why NanoFilters are essential →

Without waterline cleaning, the Dolphin Explorer E20 won't clean the dirtest part of your pool. The Explorer E20 only has partial wall climbing.
Why Waterline Cleaning is Needed →

Real reviews from verified customers on Google.
John Rodriguez of "Poolbots" recommended the Dolphin Sigma for my 20x40 Saltwater pool. I have to say, "John was correct...this thing is a beast!" I live in the SoCal desert and the Sigma picks up the fine dirt, sand and phosphate residue. John answered all of my questions. Shipping was quick! Semper Fi — USMC 1984-1992
"Patient, knowledgeable, and took the time to answer all of my questions thoroughly."
Jose provided clear and detailed information about the pool cleaners. His professionalism made the whole process stress-free.
I wish I would have converted my pressure side vac to an electric pool robot a long time ago. It cleans 10x better and completes my pool in 90 minutes.
"Without her multiple emails to the company, this would never have happened."
Shannon assisted me with an ongoing issue since May 2025 with a manufacturer. She went the extra mile and followed up!
Excellent customer service and super fast shipping. I highly recommend Poolbots for all your needs.
"I asked to speak to a human — and was told 'I am a human!'"
I clicked "chat" expecting AI. I was so pleased this company still has human interaction. John was great.
I really appreciate the opportunity to try a robot and be able to swap it. Great return process and customer service.
"A far better and more informed purchase option than Amazon."
John went out of his way to go over all the different units and what might be best for my pool. Absolutely awesome customer service.
"Truly treats you like family."
I had a few issues with my product, but Jose did an amazing job helping me and stayed in constant communication throughout the entire process.
"Jose helped fix my incorrect shipping address... saved me a lot of grief."
His help was excellent. Quick intervention prevented a lost shipment.
"Because of John, I bookmarked Poolbots and will use them for everything."
He was very knowledgeable, professional, and interested in getting you the right product — not just making a sale.
"John was amazing. I had no idea what I needed."
He was very patient. After giving me multiple options and explaining the differences, he offered the perfect unit for my pool.
"Call John, you won't be sorry!"
John guided me through the process of selecting the best pool cleaner robot for my needs. Very highly recommend!

Saved me so much time this summer. I would make this purchase again in a heartbeat.
We love our new dolphin pool robot. It takes only a couple of hours to clean our 14x28 rectangular pool. Saves us so much time from having to manually clean the pool - so convenient. Drawbacks are that it does not vacuum our stairs (which is not a big deal) and the chord could be a few more feet long so accommodate plugging it in to a receptacle. Our one corner of the pool gets neglected because the robot struggles to get that far and our receptacle inside our pool shed isn’t even that far. Once we have our exterior receptacle I’m sure it will just reach and get every inch of the pool. We are very happy with our purchase!!
Does a great job!
Easy to use, frequent cleaning of the floor, walls keeps the algae under control with lower levels of Bromine
The media could not be loaded. What do you buy, this is not a looks kind of thing. Our pool is a fitness pool 50' x 11' so pretty easy task for a robot. We live in desert so sand can be an issue and this DOLPHIN Explorer E70 does an amazing job with that. Positives: Easy to set up with App. You will need a good network connection I guess, we had no issues. With the provided carrier easy to move around. Just does its job, no issues with cord or pool filter hangups. App is pretty easy to use with one exception. Issues: Maybe it is me, but I have calibrated this unit for pick up but it never works. In fact it seems to mess with me and it goes to the opposite side of the pool for pick up. The manual controls are difficult at best to use but I can get it close enough but I should not need to do this as I use the same enter and exit location. My indoor vacuum knows there it started for no problem, just sayin. This unit seems to struggle with steps, if does not really do much except entertain me. I brush steps well before putting the DOLPHIN Explorer E70 in for duty. Tanning or Baja deck, it is so close but has never learned to not attempt the tanning deck but works well when I use floor only mode. It just does not seem to learn our pool very well, yes it is connected to the same network but compared to our home vacuum, it seems lost on every duty. Overall it is a 5 star and fell it was the best value on the market today. I wold suggest getting an extended warranty if you use your pool robot a lot... read the reviews. We hope to get 5 to 6 years of use and we take extreme care of our equipment
No, we never charge a restocking fee ever! We know a robotic pool cleaner is a big investment, which is why we offer 30 Day Trials on all robotic pool cleaners!

If your Dolphin powers on but does not move, try checking the tracks for any debris or obstructions. Also, check the drive motor and impeller for any damage or wear. If you are still having issues, contact Maytronics customer support for further assistance.
If your Dolphin's power supply is not turning on, check to make sure it is properly plugged in and that the outlet it is plugged into is working. If the power supply is still not turning on, contact Maytronics customer support for further assistance.
If your Dolphin Explorer E20 is not cleaning the pool properly, try checking the filter bag for any debris or blockages. Also, check the brushes and tracks for any damage or wear. If you are still having issues, contact Maytronics customer support for further assistance.
The handles on your Dolphin are for lifting and carrying the unit, while the floats are designed to help your Dolphin navigate around the pool and maintain proper buoyancy.
To remove any debris or obstructions from your Dolphin's tracks, turn off the power supply and carefully remove the tracks from the unit. Use a soft brush or cloth to clean the tracks and remove any debris. Once clean, reattach the tracks to the unit.
If the power unit LED indication is off even when the charger is connected, please try the following steps: 1) Unplug the power supply from the outlet and wait for 10 seconds. 2) Plug the power supply back in and check if the LED indication turns on. 3) If the LED indication still does not turn on, contact Maytronics customer support for further assistance.
