Why doesn't Wi-Fi stay connected to the Maytronics One app?

Short answer: Dolphin robots do not stay connected to Wi-Fi or Bluetooth while operating underwater.

Try this first

Take the robot out of the water, then press its power button or connect it to the charger. For best results, charge to at least 50% before reconnecting.

Easy About 15 min Tools: Robot charger, Maytronics One app

The fix

Step by step.

Your Dolphin robot cannot maintain a Wi-Fi or Bluetooth connection while operating in the water. If it was connected previously, it will reconnect to the app automatically after you take it out.

If your cordless robot has trouble reconnecting to the Maytronics One app, follow these steps:

  1. Step 1Take the robot out of the pool

    Remove it from the water before trying to reconnect.

  2. Step 2Activate the connection

    Press the robot's power button or connect it to the charger to re-establish the connection. For best results, let the battery reach at least 50%, shown by the second battery level bar, before attempting to connect.

  3. Step 3Check the Wi-Fi frequency

    Confirm that your router is configured for 2.4 GHz Wi-Fi only.

  4. Step 4Separate dual-band networks

    If you have a dual-band router, we recommend separating the 2.4 GHz and 5 GHz networks. Give each network a different name so you can tell them apart.

  5. Step 5Check signal strength at the charger

    Make sure the Wi-Fi signal is strong where you charge the robot. If needed, ask your internet provider about installing a 2.4 GHz Wi-Fi extender.

  6. Step 6Reconnect through the app

    Once the robot is charging, open the Maytronics One app and reconnect the robot.

  7. Step 7Unpair extra users

    If more than one user is connected, unpair the extra users in the app settings, then try connecting again.

Connection limits

Bluetooth can recognize up to 10 devices, but only one user can connect through Bluetooth at a time. Wi-Fi allows up to 5 users to connect.
