I have owned several Cirrus vacuums over the past 20 years. I particularly like the commercial model for commercial space. The 50-foot workout cord can cover a lot of ground, and yes it's a lot heavier than the others, but it also means it's got enough weight to keep your head on the carpet and isn't cheaply made and holds and holds up. This model is great for quickly covering a large floor area. It's not as nimble as the Shark or Dyson, but it's not as well made either. I buy mine locally for over $100 less than what Revain says.
