Explorer E20 is missing...

Dolphin NanoFilter Cartridges

No NanoFilters™

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

Why NanoFilters are essential →
Dolphin Dual Motors

Missing Commercial-Grade Motors

The Explorer E20 uses the standard motors, rather than utilizing the more powerful, commercial-grade motors found on the ProLine™

No Waterline Cleaning

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 →

Overall Rating: 3.7

B K - 5 Stars

Saved me so much time this summer. I would make this purchase again in a heartbeat.

AJ - 5 Stars

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!!

R G H - 5 Stars

Does a great job!

Jeff Jackson - 5 Stars

Easy to use, frequent cleaning of the floor, walls keeps the algae under control with lower levels of Bromine

BeHappy - 5 Stars

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
