Has anyone else had issues where the main brush stopped picking up anything at all? The vacuum still sucks up dirt, but the main brush stopped picking up everything after about 2 months. The app doesn’t say the brush should be replaced (not that I could yet anyhow with the non-available parts), I’ve clean it throughly from hair, but nothing seems to work. I’ve logged two issues with Wyze support with no answer. Anyone have a solve or is mine defective? I loved this thing early on and still want to love it, but I need it to work like it did originally…
