When the robot is fully charged I remove the charger from the power supply and remove the RoboVac from the charger.
All is disconnected.
I am always a little disturbed by the lights of the charger and the robot.
And I disconnect usually as many power consumers (stand by mode)
which I do not need all the time.
Can be done by "smart-home-functions" or I do (As a Neanderthaler ) by switching off the power outlets by hand.
