Mark, thanks I do not expect this to be a problem, I am going to clean another section of my carpet today and use one of the other gliders. I am sure it will do the job without causing any fraying. Wether or not the carpet I cleaned already has some fraying caused by using the holy glider I am not 100% sure. It could just be some wear that has naturally progressed over time. Anyhoo thanks for your input................Sam
