We have a Numatic Henry and it runs circles around the most expensive Dyson. While the Dyson seems more powerful on paper, in reality the Henry sucks up more dust, grime and pet hair. Our Henry is 18 years old, survived falling down the stairs, a complete house remodel and basic family life with kids.

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.
