Why is DEEBOT cleaning for a shorter period of time?

(1) If the robot has not been used for a long time, fully charge it on the Docking Station. The battery level can be checked in the App.
(2) Cleaning times will become shorter when the battery is near the end of its service life. If the cleaning performance is not sufficient, please replace the battery.
(3) If the problem persists after following the steps above, please contact ECOVACS Customer Care.
