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

Most asked From Maytronics support, updated 2026-04-16, rewritten for clarity. Applies to 5 models.

The fix

Step by step.

Our cordless models, the EON™ and Liberty 400/600, do not remain connected to Wi-Fi or Bluetooth while submerged and operating in the water.

After removing the robot from the water, if it was connected before, the Wi-Fi connection between the robot and the app will automatically reestablish.

To use the Maytronics One app, connect to the robot via Wi-Fi, configure your desired cleaning mode or weekly schedule (UltraRun™ Mode/Eco Mode), and then place the robot in the pool to begin the cycle. Once the robot is in the pool, it will run the selected program independently.

Our corded units allow for continuous Wi-Fi connectivity, as the connection is maintained through the power supply, which remains outside the water.

Note- The Liberty 400 pairs via Bluetooth only to the MyDolphin Plus app.
