The "elbow" angle is awful.  I end up with it clogging there almost every time I use this vacuum and end up having to use a vent brush to clear it out.  For a vacuum that is supposedly for pet clean up, it's inability to handle cat hair without clogging is a major fail.  IMO this is a waste of money.  They could have rounded that angle so that it doesn't cause that problem, but it's a relatively sharp angle, so it clogs.
