Dolphin Eon 120D – Complete cordless cleaning for pools up to 15 metres

Why choose a cordless pool robot?

A cordless pool robot eliminates the most common issue of corded models: tangled cables that limit reach and make operation more difficult. Without a cable, the robot moves freely throughout the pool, including hard-to-reach areas such as steps and shallow platforms. Installation is immediate – simply place the robot in the water. No need to connect to pumps or electrical systems. Compared to hydraulic models, a cordless electric robot like the Dolphin Eon 120D has its own filtration system and does not rely on the pool pump, helping to reduce overall energy consumption.

Features of the Dolphin Eon 120D

DebrisLock™ Filtration – 4x cleaner water with self-cleaning filter

The Dolphin Eon 120D uses patented DebrisLock™ technology, an ultra-fine filtration system that captures microscopic particles. The filter automatically compacts debris, extending cleaning cycles and reducing how often the basket needs to be cleaned. The filter is accessed from the top of the robot, with no need to turn it over.

SmartMap Navigation – Route adapted to your pool shape

SmartMap navigation scans the pool layout, shape, obstacles and surfaces — and automatically adapts the cleaning path. It works in rectangular, round, kidney-shaped or irregular pools, ensuring full coverage without unnecessary repetition.

UltraRun™ Mode – Up to 2.5 weeks of cleaning on one charge

UltraRun™ mode optimises the 9600 mAh battery to keep your pool clean for up to 2.5 weeks without recharging. The robot alternates cleaning cycles of 1h30, 2h or 2h30, covering floor, walls, waterline, steps and submerged platforms in each session.

Maytronics One™ App – Full control from your smartphone

The Maytronics One™ app allows you to schedule weekly cycles, monitor battery status, receive full filter alerts and check water temperature. It also includes remote diagnostics for troubleshooting. The robot features Click-Up™: with a click on the remote, the robot moves to the nearest wall for easy removal from the water.
