Yes, all of the older Convertibles have a beater bar.
I usually use attachments for hardwood floors (they made a great floor brush). But, if you have good, unworn brushes, THEY touch the floor, the beater bar doesn't strike the surface. Hundreds of vacuums... 11 room house, never a problem here. You owner's manual tells you to never set the vacuum cleaner on 'low" when using it on hard surfaces. Always put it on "medium". If/when I do, if I turn the cleaner off ON the hardwood floors, I hear the brushes sweeping the floor on the slowdown. I hope this helps.
