For Wi-Fi Robovacs, you can see the estimated battery level on the app.

To have the real-time percentage indication, the vacuum would need to send data all the time, which consumes some power. Also, the RoboVac's WiFi connection might be inconsistent, so the remaining power indication might be inaccurate.
