I have had Nutone central vacuums and accessories in my home for 28 years. That replacement brush sucks. This has been giving me problems for two months. It "freezes" and power surges. It was never quite right. Unfortunately he is now six months old and I can't even complain. Having bought the Nuton for all these years I am completely shocked at the cheap construction and the fact that in less than six months it does not serve its purpose at all.
