The fix

Step by step.

A few reasons may be preventing the MyDolphin Plus app from connecting to your robot.

Click below on the option that applies to you to see the troubleshooting steps:

For My Dolphin Plus™:

My Power Supply AND/OR Motor Unit has been replaced and I cannot connect to the App anymore

If a new or replacement power supply does not locate the robot, there are a few steps that will help resolve the issue:

  1. Delete and reinstall the MyDolphin Plus app.

  2. Reset the power supply unit by disconnecting it from the electrical outlet for 60 seconds and then plug it back in.

  3. Place the robot back in the pool and turn it on using the power supply unit's ON/OFF button. Let the robot operate for about 5 minutes. Do not connect to the app yet.

  4. While the robot is working in the pool, make sure that you are standing near the power supply unit. Install the MyDolphin Plus app and then reconnect.

I have connected previously, and cannot connect anymore.

  • Make sure that you are using the latest version of the app. Complete the app update if needed.
  • Verify that the network name has not been changed and that the phone is connected to the same network the app intends to connect.
  • Please reset the power supply and router by disconnecting each from the electric outlet, waiting 30 seconds, and reconnecting.
  • We suggest deleting and reinstalling the app, ensuring you have allowed the pop-up notification "Allow while the app is working". Make sure you have enabled all operating conditions needed for the app to work correctly (Location Services, Bluetooth, 3G/4G, or Wi-Fi with at least 60% in signal strength).
  • Verify that your Wi-Fi network is set on 2.4GHz only and not on 5GHz or dual band.

I am connected, but the signal keeps disconnecting

It could be that your pool area's Wi-Fi signal is low, which could cause connectivity issues.

To resolve this issue, we recommend the following:

  • Place your power supply closer to your home router/extender.
  • Place your router closer to the power supply.
  • You can also use an extender for the Wi-Fi signal. (In this case, please consult with your local internet provider.)

For more help, you can also consult the General Wi-Fi Connectivity Guide.

If you receive a message that MyDolphinPlus is incompatible with your robot model, download the MyDolphin App or verify if your robot model includes an app in the User Manual here.

For My Dolphin™ :

The power supply is too far from the smart device, or your Bluetooth® is disabled or not working correctly.

Try these steps to resolve the issue:

  • Try to turn off and then turn on the Bluetooth® in your smartphone
    For IOS – Go to Settings → Bluetooth®.
    For Android – Go to Settings and turn the Bluetooth® icon off/on.
  • Get closer to the Power Supply.
  • Ensure that you don’t have any interference/obstacles.
  • Please turn the power supply OFF and then ON.
