If there are girls with long hair in the house, the hair tends to get wrapped around the roller brush. I don't know yet what to do about that. But I don't like the bagless kind of vacuum.
I have long hair... grew up in a house having 8 women, all with long hair!
The answer to the hair wrapping around the brush is to regularly take the brush out of the vacuum, and to use a scissors with a very sharp lower point, and cut straight down the side of the roller, so the hair strands can be gathered off the brush.
As to the bagless kind of vacuum, I agree! It's a way to spread dust!
I kept going thru one vacuum after another, until I decided enough of this.
I couldn't afford a new Kirby, so I saved up a couple hundred dollars, and watch Craigslist.
That beat up old vacuum I got for $200 has been indestructible for years. And the suction is still great. Yes, it's heavy... but why use a lightweight vacuum, and then pay for a gym membership to tone the arms?
