What should I do if my phone couldn't authenticate connection? (especially for Android)

During the process of connecting eufy RoboVac to WiFi, you might see the following error message: Your phone is not connected to the “eufy RoboVac 15C Max xxx” network. Please reconnect to eufy RoboVac 15C Max xxx in your phone WiFi list to continue setup. Please go to the Wi-Fi Settings and connect the RoboVac’s WiFi manually. 


If you see the following message “Couldn’t authenticate connection” when connecting to it, please forget this network and reset RoboVac's WiFi. Then start the whole connection process again. 


After you connect to the RoboVac’s WiFi successfully, you might receive a pop-up message “Internet may not be available”, please select "keep WLAN connection" and use the back button to go back to the eufy Clean app instead of switching apps, because switching apps may cause the connection to fail.


If you need further assistance, please contact us.
