I just come across a post on facebook on a hardwoodfloor group talking about beater bars that most vacuums have and why they aren't good for cleaning hardwood floors. My question is this what is a beater bar and how can I tell if my vacuum has one? This is something I will research once I get to the point I want to clean any hardwood floor I install.

Its that thing underneath with brushes that spins around. That will scuff up any finish.

Thanks man,looks my vaccum cleaner is gonna be useless then in the near future LOL
