I tried bag-less around 2011. I returned the vacuum promptly and ran to Sears for the Intuition. Emptying out the container was a desert dust storm and the vacuum lost suction rapidly. The filter would get dirty fast. It was one of those Model T moments of "never again"
Forgive my crass / negative reply
I've always insisted on "Bagged" machines, and since I had worked for Eureka, chose that brand. - they were always sturdy machines.
The Hoover bagless "Air Steerable" machine was given to me by a neighbor who claimed it didn't work right, and was going to trash it.
Well, The machine was clogged with pet hair due to lack of cleaning, which I did.
I also performed a complete overhaul, and wound up with a pretty damned good vac!
It's got surprisingly strong suction, I like the way it "steers" around furniture, and it's lighter than most other uprights.
It's also quieter than my Eureka's, and the brush roll automatically adjusts easily for carpet to hard floors. - the brushroll motor can also be turned off manually, and it automatically turns off if the handle is upright, as is the case when using the hose.
That dirt cannister is easily removed by pushing the top button, taken to a trash can and push the bottom button which pops open the bottom and the dirt simply drops out. - no muss, no fuss.
On occasion, that dirt cannister is easily washed out too.
The main filter also is washable, and the Hepa Filter is also easily replaceable.
It also had a whistle alert if the suction is blocked by something.
The only thing that annoys me is when using the hose and optional turbo attachment on stairs is that the suction causes the hose to "shrink" and retract.
So even though I was always a dedicated Eureka fan, I have to give the Hoover my honest positive review.
