The way it looks has the Fa. Miele learned from their mistakes and handle this constructively slightly revised but with a big impact. The square opening is no longer consistently open but closed from the inside so that now instead of through hole is a blind hole at the site. This design flaw has been fixed and the break away. I am happy that I got this revised version and hope that despite this mistake from now my good old vacuum cleaner (8 years old) Type of S5210, S5, with the label: Best Friend still reliably provides good services and remains for me a few years, just as he is, as a best friend when it comes to vacuuming at home, receive. Strong buy recommendation!
