Hi,
My Eufy is making a loud rattling/rubbing sound as it cleans. It appears to move normally and vacuum despite the noise. I have removed and cleaned all the rotors/brushes. However, the noise persists and seems to be getting worse. Here are two short videos of the sound it is making. Let me know what else to try.
