Terrible product. Error mob cover

Peace of advice. Dont buy this robot vacuum cleaner. Since i bought it in 2025 i quickly got a the mob cover error. Nothing worked (cleaning the device etc). Dreame support offered to send it to poland for repair but i read a lot of bad thing about it ( repair takes months etc). I removed thr mob cover and this workd for a year. But now the error is back. Even without the mob cover present... you do not expect this from a device which costs 1200 euro's..
