My Dyson from 2004 is holding up well. Not a whole lot of maintenance required. I had a Bissell from 2007-2014 that worked decently, but I gave it to a friend. I think it's still running. I bought a new Dyson in 2015 but it ended up having all sorts of problems. I am gonna ride the 04 out until it breaks, then maybe onto Riccar or Miele.
