Query: What the (?!?!) with the positive reviews?

I've been a housekeeper for 15 years, and have clients who own this vacuum. When my Dirt Devil got a short, I was forced to use one of these. No suction. It's impossibly heavy, so good luck on stairs. I asked my client about it, she regrets buying it. I checked out my other clients Dyson vacuums, and it's the same story. I'm very confused by the positive reviews, everyone that I know who owns one, hates their Dyson.
