Fixed a stuck vacuum motor (common problem with these). Apparently these often only last a year or two from new because the motors aren't well protected from moisture (and perhaps they're often left with the dirty water chamber unemptied). My guess is this'll last for years now that the common problem has been identified and addressed (and if it remains addressed). I have a few of these that I've revitalized.
