Query: Best vacuum I've ever used

After just one use, I was sold on this vacuum. I've used plenty over the past 20 years and have never had one that picked up as much as quickly as this one. Most specifically, pet hair is a cinch, even on furniture (with the powered attachment). Never really used the disinfectant stuff that came with it because it's kind of a hassle.Yeah, it is heavy, but it doesn't tip over when I use the attachments on the stairs or stretch it out anywhere.
