I received my new Wyze Vacuum and just love it. Had no issue with setup. I read all the documentation and found a problem. The doc referred to an edge brush. I tore the packaging apart. I looked everywhere for that brush. I was just about to call Wyze to say my package didn’t include that brush. Well I’ll be damned…that brush was located inside the body of the vacuum. I felt so stupid. So if you go looking for “that brush” open the unit and you will see it there as plain as day
