Owner questions

Questions about the Nautilus EON 120d.

Why doesn't my cordless robot respond to the app while underwater?Fix

Short answer: Your cordless robot disconnects from Wi-Fi and Bluetooth underwater, so select its cleaning program in the app before placing it in the pool.

Cordless EON™ and Liberty 400/600 robots do not maintain a Wi-Fi or Bluetooth connection while submerged and cleaning. Once underwater, the robot follows its selected program on its own, without an active app connection.

Set the program before putting the robot in the pool

These Maytronics One app instructions apply to Dolphin EON 100, Dolphin Nautilus EON 100, Dolphin EON 120d, Dolphin Nautilus EON 120d, and Dolphin Liberty 600.

  1. With the robot out of the water, connect to it over Wi-Fi in the Maytronics One app.
  2. Choose your cleaning mode or weekly schedule (UltraRun™ Mode/Eco Mode).
  3. Put the robot in the pool to start the cycle. It will carry out the program you selected independently.

Reconnecting after cleaning

If the robot was previously connected, its Wi-Fi connection to the app returns automatically after you take it out of the water.

Other connection types

Corded robots can stay connected to Wi-Fi throughout cleaning because their connection runs through the power supply, which stays outside the pool.

Liberty 400 uses Bluetooth only and pairs with the MyDolphin Plus app, not the Maytronics One app.
