Re Miele - my sample size of one dates to 1987 and still is my main vac. So at some point in the past they were probably quite good (or I got really really lucky). FWIW
Ha awesome. Before I bought, I did some reading about vacuums that repair shops thought were good, Miele seemed to top the list at the time. It’s been great, despite suffering a decent amount of clumsiness-related abuse.
