Troubleshooting · Connectivity & Setup

How do I connect my Dolphin to Wi-Fi with MyDolphin Plus?

Short answer: Pair your Dolphin through Bluetooth first, then connect it to a 2.4 GHz Wi-Fi network in MyDolphin Plus.

Try this first

Stand near the power supply, close and reopen MyDolphin Plus, and retry setup with Bluetooth on and a 2.4 GHz Wi-Fi signal of at least 60%.

Most asked Easy About 10 min Tools: Compatible phone or tablet, 2.4 GHz Wi-Fi network, Wi-Fi network name and password, Dolphin power supply and blue cable

Based on Maytronics support, updated 2026-04-26, rewritten by Poolbots' pool experts. Applies to 25 models.

The fix

Step by step.

MyDolphin Plus from Maytronics uses a cloud connection to let you control your Dolphin in real time, wherever you are and whenever you need to.

Watch this quick video for help with your first connection, or follow the steps below.

Phone and tablet compatibility

  • Apple: iOS 10 or newer on an iPhone, iPad, or iPod.
  • Android: operating system version 5 or newer.

Wi-Fi requirements

  • The network must transmit on 2.4 GHz only.
  • The password must be fewer than 32 characters, with no spaces or special characters such as #, %, &, ", $, or £.
  • Signal strength at the power supply must be at least 60%, or 2 out of 3 bars.

If your network cannot meet these requirements, you can use a Bluetooth-only connection instead.

Step 1Get your phone or tablet ready

  1. Connect your phone or tablet to your Wi-Fi network. Check for at least 60% signal strength, or 2 out of 3 bars, where the power supply sits.
  2. Have your network name and password ready. The password must contain fewer than 32 characters.
  3. Turn on Bluetooth on your phone or tablet.

For Android, turn on GPS and location services.

For iOS 13 only, give MyDolphin Plus permission to use Bluetooth and location services while the app is running.

Step 2Prepare your Dolphin

  1. Plug the power supply into an electrical outlet and attach the Dolphin's blue cable to the power supply.
  2. Check that the connectivity LED begins blinking blue.
  3. Put your Dolphin in the pool water.
  4. Use the power supply's on/off button to begin a cleaning cycle.

Step 3Pair the app and connect to Wi-Fi

  1. Open MyDolphin Plus.
  2. Allow all permissions the app requires.
  3. Create an account, or sign up with your Gmail, Facebook, or Apple account.
  4. Scan the QR code on the side of the power supply. You can also select "Search manually" below the QR scanner. Once Bluetooth finds your Dolphin, the app begins pairing with the power supply.
  5. Wait for a steady blue connectivity LED and a confirmation message in the app.
  6. The app will then prompt you to connect to Wi-Fi.
  7. Check that the Wi-Fi network name field shows your network's name.
  8. Enter your network password, which must be fewer than 32 characters, and select Continue.
  9. Allow up to 2 minutes for the connection, depending on Wi-Fi signal strength. The power supply LEDs alternate between blue and green during this process.
  10. Look for a steady green connectivity LED and a confirmation message in the app.

If the first Bluetooth connection fails

  1. Review the permissions granted during signup, including location and Bluetooth Low Energy (BLE). Confirm that the Wi-Fi, cellular, and BLE connection requirements are met.
  2. Check that the blue cable is properly attached to the power supply.
  3. Look for a picture of your Dolphin in the app. If no robot appears, contact Poolbots' pool experts through live chat or phone. Have a screenshot of the setup screen where you are stuck.

Once pairing is complete, you can name your Dolphin, register its warranty, and use the app's features.

If the app stops on the loading screen

Setup has three connection stages. The percentage shown on the loading screen can help identify where the connection is failing.

Stage 1: 0-10%, sending Wi-Fi details to the power supply

After Bluetooth pairing, your phone sends the Wi-Fi information to the power supply. A stall here can mean that the connection dropped or the information did not transfer correctly.

  1. Close MyDolphin Plus, open it again, and retry the connection while standing near the power supply.
  2. Recheck the Wi-Fi network name. It should be entered correctly, with no foreign letters or characters.

Stage 2: 10-50%, connecting the power supply to the router

The power supply checks the Wi-Fi requirements, including the 2.4 GHz frequency, as it connects to the router. This stage can take up to 2 minutes.

  1. If setup remains at this stage, review all the Wi-Fi requirements above and confirm that your network meets them.

Stage 3: 50-90%, connecting the power supply to the cloud

A failure at this stage points to a problem with the cloud connection.

  1. Try resetting your router.

Supported Wi-Fi security

MyDolphin Plus supports WPA/WPA2-Personal and WPA2/WPA3-Personal.

Important compatibility limit

Buying a Wi-Fi-compatible power supply will not make a non-Wi-Fi Dolphin compatible with MyDolphin Plus.

Check the user manual to confirm whether your Dolphin supports the app.
