Oreck XL is difficult to move on carpeted floors. I replaced the worn out brush with this one, thinking I'll use a different vacuum. This is the same product that costs three times as much on Oreck's website. Highly recommended, don't buy a new vacuum, buy a new brush. Installation is easy, unscrew the 5 screws from the bottom, remove the brush strap and put on a new one. A ten minute job if you decide to clean the bottom of the unit when you change brushes.
