I have a Dyson, as you can see by my avatar I sometimes live in "fur lined" house, when he blows coat in the spring. I love the suction .... but I found out the hard way it was not a good choice for my carpet. I have a looped carpet in my living room. The dyson finds every loop and sometimes grabs one and pulls it . I have carpet yarn runs that can are over 18 inches long.... that's how much gets pulled before I can get the machine stopped. Once that pull has occurred even though I will trim it down the difference in the depth then of the loops next to the pulled area are now very likely to be new pulls the next time I vacuum.
