Viomi V2 Pro - noise working


May 10, 2022
Few days ago I started vacuuming, leave the flat and suddenly I got notification "Error". I came back and saw that viomi just sucked part of my blanket. I pulled it off and restart robot. After this it sounds like... rocket ship? I don't know.. I disassembled robot, clean it up but unfortunately nothing special occur that could blocked working and sounds like that. I cleaned up brush, use WD40 for better clash aaaand... Nothing. I assume that could be main brush engine or suck engine because when Viomi is mopping there is no sound like that. Could you help me with diagnose?
