I have bought a second Miele and love that one also.
The part cost $15. 00 and $15. 00 shipping. That is crazy! We ordered the wrong part. So we didn’t use it. I had replaced the wand years ago and forgot about that. Saw the box and took that button off and put it on the new wand. Now we can extend the vacuum. It’s been working over 30 yrs!
