Why does my Automower® robotic lawn mower make a buzzing sound, almost like a bee?

If your Automower® robotic lawn mower makes a buzzing sound when mowing, almost like a bee, it is usually because there is an imbalance in the cutting system caused by double blades on one of the blade screws.

Make sure that there is only one blade attached per screw. If this does not help, contact your local dealer for further troubleshooting.
