Troubleshooting · Maytronics One App

Why isn't my EON behaving properly?

Short answer: Update your EON's software in the MaytronicsOne app before trying other troubleshooting steps.

Try this first

Fully charge your EON, disconnect it from the charger, and use the MaytronicsOne app to check for and install any available software update.

Most asked Easy About 10 min Tools: Smartphone, MaytronicsOne app, Robot charger

Based on Maytronics support, updated 2026-10-11, rewritten by Poolbots' pool experts. Applies to 3 models.

The fix

Step by step.

Applies to: Dolphin EON 100, Dolphin Nautilus EON 100, Dolphin EON 120d.

Start by checking that your robot has the latest software. Updates provide fixes, improvements, and capabilities that help your EON work as intended.

Update your EON's software

  1. Step 1: Prepare your phone Download the MaytronicsOne app and turn on Bluetooth on your smartphone.

  2. Step 2: Charge and disconnect the robot Charge the robot fully. Check that the battery indicator displays three solid green bars, then disconnect the robot from its charger before moving on.

  3. Step 3: Sign in to the app Open the MaytronicsOne app. Create an account or sign in to an existing one, then enter the validation code you receive by email.

  4. Step 4: Turn on Bluetooth pairing Hold the robot's power button for 3–5 seconds to activate pairing. Look for a blinking blue LED.

  5. Step 5: Pair your robot Follow the app's on-screen pairing instructions. When your robot appears, select it to start pairing. Your smartphone must not be connected to another Bluetooth device during this step.

  6. Step 6: Complete the software update If the app offers a software update, complete it. This is an essential part of troubleshooting.

    During the update:

    • Keep your phone close to the robot.
    • Keep the app open and stay on the update screen until it finishes.
    • Allow the update to finish without interruption.
  7. Step 7: Set up Wi-Fi After the software update finishes, connect the robot to a 2.4 GHz Wi-Fi network. You can skip this setup and connect to Wi-Fi later if you prefer.

  8. Step 8: Check the connection light A successful connection is indicated by three LED blinks, followed by a steady blue light.

Important: Before moving on to any other troubleshooting, confirm that your EON is running the latest available software.
