I have the bagged version of this machine...
And while it’s not the greatest vacuum in the universe, it’s not the worst, either, especially when you consider that it only cost around $200 in today’s money. (I can’t speak for the bagless models, though, as I’ve never used one, though I imagine they wouldn’t perform as well.) I think it’s safe to say that they (the bagged versions) are certainly better than a lot of the stuff at big box stores these days. My parents had a bagged version too, and it lasted 17 years. (Mind you, the house is mostly carpet, so it saw a lot of use.) I doubt you’d see that from most box store vacs today.
