Query: bad vacuum

Hepa filters are no easier to change than bags -- and you have to change them twice a year -- [the money] for the filters that's bad value. Vacuum is also heavy and clunky. There are two other filters that need regular changing which is a pain. And after a year and a half, the thing isn't working properly and is probably destined for the garbage. Don't bother with this one.
