[USER=3205]@crazykirbydude[/USER] Miele has been using circuit boards for over 30 years they rarely fail and I would say they are one of the most reliable components in the vacuum cleaner it self. It simplifies and removes the mechanical bits that can fail especially when you look at older Electroluxs is that had his complex vacuum lines and multiple electrical switches.
As for the Miele cx1 it is a Bagless machine kind of behind the times I believe me love purposely made it this way in order to sell more bagged machines.
