Not impressed

So far the thing was impossible to connect.  I checked every router setting my phone followed all the help files I could find, it never scanned the QR code from my screen, after two hours it finally connects.  It tries to map, quits halfway, error error error, can’t find a code in the app, try remapping several times, same thing.  Save an incomplete map, fine. Try to clean figure it will learn the map via vacuuming, nope goes 32ft and quits error again try it two more times, same thing.  Most expensive piece of trash I’ve ever bought.  I’m so irritated I could scream, bc I wanted it to work
