My Pure I9 doesn’t clean any carpets in my home. It just skips them. They are regular thin carpets and my previous Neato had no problems cleaning them.
How can I force the machine to clean the carpets as well?
There is no way to force the robot to clean carpets. But you can make it easier for it to clean by removing obstacles on the carpets. Also make sure that carpet is flat and not 'wavy'.
Or you can try to to use spot cleaning on the carpet.
