Belt and brush roll are perfect! I feel like I have a new vacuum cleaner again! It was very easy to install it yourself! (I didn't have to ask my husband to do this for me!) My brush still worked well, I bought this purchase primarily for belts so the brush was a plus! - KILLER DEAL! - anyway I'm so glad I switched rollers - it makes a huge difference! I replaced the belt and pulley about a week ago and it's still working great! My vacuum cleaner thanks me! My Oreck is an older model. This is the 40th anniversary edition of the Oreck XL2. I've had it for a long time and it still works great! The best vacuum cleaner I've ever had! I lasted the longest! I've attached a picture of an Oreck XL2 identical to mine as a link.
