I would like to say that these replacement parts are as good as the originals, but unfortunately they are not. The side brushes in particular seem to be longer and stiffer, which sounds good at first glance, but the brushes are long enough to fit under the Deebot N8 pro plus wheels. I've tried cutting them to length, but the stiffness of the brushes seems to slow the motors and sometimes even stop them. The rest of the elements seem to work fine.
