Unfortunately, I started my acquaintance with this model from a marriage (the vacuum cleaner was dumb, drove chaotically and gave error 8 - that it was tangled in the wires). The problem was probably in the leader (such a red thing that rotates from above). I had to return it the first day. There were no problems with the second device that was issued for replacement, and the vacuum cleaner still managed to pleasantly surprise.
