The battery is at the voltage threshold. When the robot vacuum cleaner is connected to the base station for the first time, the required battery voltage might not be reached during start-up. The battery does not charge.
Switch the robot vacuum cleaner off.
Slide the robot vacuum cleaner onto the base station so that it is touching the charging contacts.
Take the robot vacuum cleaner off the base station after 5 seconds.
Repeat both steps 5 times.
Leave the robot vacuum cleaner on the base station to charge for a further 5 minutes.
Switch the robot vacuum cleaner on again.
The battery charging state indicator on the robot vacuum cleaner flashes.
Switch the robot vacuum cleaner off at the power button on the remote control (standby).
Now give the robot vacuum cleaner 3–4 hours to fully charge.
If the fault persists, please contact Miele Service.
