Dolphin EON Cordless Robotic Pool Cleaners

EON is the newest cordless platform from Maytronics. Both models cover the floor, walls and waterline, and go where corded robots cannot: steps, sun ledges, corners and safety ledges. The 120D adds a BackWash filter that cleans itself between runs. Each is under the Nautilus EON name and as the EON 100 and 120D.

Dolphin EON buying guide

What separates the models, and which current Dolphin to price each one against.

EON 100 vs. EON 120D

Both EONs are rated to 50 ft and clean the floor, walls, waterline, steps, corners and sun ledges in a 2-hour cycle, controlled from the Maytronics One app. The EON 100 uses a fine filter kit you rinse by hand. The EON 120D uses a BackWash filter that flushes itself, which is the feature to pay for if you run the robot several times a week.

Nautilus EON or EON?

They are the same robots. One version is as the Dolphin Nautilus EON 100 and Nautilus EON 120D; the Maytronics catalog calls them the EON 100 and EON 120D. The pages below show both so you can compare price and warranty before you buy.

Quick answers

Dolphin EON Questions

Is the EON corded or cordless?

Cordless. Each EON runs on a battery, charges on a dock, and is controlled from the Maytronics One app.

What does the BackWash filter on the EON 120D do?

It flushes the collected debris out of the filter automatically, so you empty it far less often than a standard basket.

EON or Liberty?

The EON cleans steps, ledges and the waterline on pools to 50 ft; the Liberty 200 and 300 are lighter, lower-priced cordless robots for pools to 33 ft.
