It seems that
many Miele vacuums last about 10 years or less when I owned my store customers would bring in dead less than 10 yo Mieles to trade for new vacuums .
Compared to Aerus formerly Electrolux I still have and use my Aunt B`s 1947 model XXX I dont hear too many stories of that old Mieles still being used.
Don`t get me wrong I like Miele I love German products I drive German cars .
You rarely if ever see vintage Mieles for sale say on eBay but you`ll fing many vintage Electrolux vacuums there .
Besides Kirby , Filterqueen and Ranibow these DTD brands seem to hold up better than any TOL vacuum out there .
