In 3 words : No. Vaccum. Bag.
The bags only need to be changed a few times per year, and changing is a breeze. Compare that to the Dyson where you have to empty the bin every other time you use it. Oh, and the Henry doesn't seem to lose power as the bag gets fuller since the motor is placed on top of the cleaner.
Every part can be replaced (and are still available, for a 18 year old vacuum cleaner!) but as I said, they're nearly indestructible. And cheaper than a Dyson.
There's a reason why professional cleaners use them, I guess.
Also, unlike a fancy Dyson, it's designed to be bashed around, yanked around and generally abused. It's the Nokia 3310 of vacuums. And if a part breaks, because they're used commercially it's cheap and easy to replace.
The Toshiba bagless cleaners work well in my experience.
I started out by vacuuming the floors with my existing machine, and used tried the dyson afterwards. The amount of stuff it sucked up was very surprising.
Sure the dysons are a lot more expensive than the generic machines, but I have to say that I loved mine. It's only because I live abroad now, and I don't have carpets that I've not looked into getting another.
Other brands started to sell bagless vacuums only after Dyson first success. For other brands, bags was as profitable market.
Cleaning dust out of a bagless vacuum is bad if you have allergies.
Buying the bags is an annoyance but it is the lesser one.
I am happy to avoid buying and changing bags.
