Yes; this vacuum has a need to replace belt located under the bottom plate of the vacuum.
I have both the new Dyson Vacuum for Pet Hair Removal and this new Windtunnel High Performance Pet model. We have a cocker spaniel and a beagle. We had not intended to end up with 2 vacuums, but the following breakdown explains why:
The Dyson is excellent for hard surfaces and getting those dustbunnies (a/k/a globs of dog hair and fur) out from under the beds. The cord is supple, and the head is easy to turn and manipulate around those center legs on king sized beds and those occasional boxes we tend to keep under there. The same ease is found for vacuuming under sofas and chairs. However!! We were disappointed with the suction on our rugs. We have the short napped "oriental" style rugs on our tile floors, and expected a deeper clean after going over the area several times. Evenso, it still brought up a lot of dog hair. This is when my husband bought the Windtunnel. It does solid floors very nicely, too, but it excels on the rugs! We were astounded at the amount of hair it collected, and the machine itself is light and easy to move.
