Pet hair, it&#39;s length, the carpet it&#39;s laying on, the bristles on the roller brush, all make a different cleaning dynamic in each home. The Stealth brush and kit are one of the best, if not the best for all situations. It is what all of us use at MD who have indoor dogs. The kit will fit right into your system. If the hose to wall connection is a little tight on the older Nutone we have a simple fix for that - just scrape a bit of plastic off the hose end. Please give the Stealth Kit a test drive. www.builtinvacuum.com/stealth-kit/
