Steps4
ToolsNone
PartsNone

Works for Corded Dolphin robots with an On/Off LED and a Bluetooth or Wi-Fi power supply, such as the M600, M700, X40 Plus and Nautilus CC Plus Wi-Fi.

Short answerGreen light. Flashing green on the connectivity LED. Steady green means connected to Wi-Fi and the cloud.

What it means: The power supply is on your home Wi-Fi and trying to reach the cloud, or the Wi-Fi signal is weak.

Quick fix: Check your router offers a 2.4 GHz network.

Fix it in 4 steps

  1. Check your router offers a 2.4 GHz network.The power supply supports 2.4 GHz only.
  2. Move the power supply closer to the router.
  3. Add a Wi-Fi extender if the signal is still weak.
  4. If you changed your router, use Wi-Fi settings in the app to join the new network.

Fixed when: The connectivity LED turns steady green.

Can I still control my Dolphin if the Wi-Fi drops?

Yes. Choose the Bluetooth option in the app while you are near the robot. The app should reconnect to Wi-Fi when the connection returns.
