Satisfied, I will buy this item again in future.
I have owned my Miele vacuum for two years, recently I noticed a stale smell when I used it. I change the bag regularly so knew it must be the Hepa filter (it is recommended to change it annually) and when I bought a genuine replacement from the manufacturer the odour disappeared. There is an indicator on the component which turns colour when it needs changing which I shall pay attention to in future.
