If you have a Miele don't assume anything about other 'decent' home vacs. The Miele line is about as good as it gets; powerful, quiet, easy to maneuver, etc.
That's all true, and that's why we bought Miele. But even far less expensive vacs than Miele have adjustable brushes, telescoping handles, suction control at the top of the handle, lower center of gravity, non-marring pieces, etc, all of which lead me to not want to use a CT for home cleaning purposes..
