Easy installation. Absolutely no musty, dusty/dirty exhaust smell that I've had with all my other vacuums. I'm so glad I invested in this Miele system. Plus, it's easy to use for a 77-year-old with weak hands.
Pros
The Miele HEPA AirClean filter is ideal for allergy sufferers with a dust retention rate of over 99.9% (HEPA class 13 according to EN 1822/2011).
