whistling noise

I love my Dreame but two weeks in and it's making this whistling noise. I don't remember it being this loud the first week I had it. Is anyone else having this issue and is there a fix?

Mine is about that old also, it just doing the same thing.

It sounds like a the Omni wheel squeaking. Mine started to do that same thing shortly after I purchase. I cleaned mine and used WD-40 white lithium grease and it solved my issue.
