Game Changer! I can't confirm that it fits all Oreck vacuums, but I can say that it fits my Oreck XL Commercial absolutely perfectly. I have an Oreck XL COMMERCIAL 1 speed (on/off) (see photo) which I bought back in early 2017. It has become a champion and the best for my super fluffy bare floor home. However, I noticed that he wasn't lifting as well as he used to and was getting worse and worse. This was puzzling as the Oreck's design, unlike many other vacuums, has very little suction loss and should almost never clog as the path from collection to bag is very short. However, I took it apart (so easily) from the handle to the brush area. Cleaned up well - thought it might help. I checked the brush and belt - all looked fine. Twisted the brush. Changed the bag again long before it was even half full, just in case. I even checked the information in the product brochure. Everything looked good! But actually nothing has changed. I've done all of this multiple times over the course of several months. My vacuum cleaner just wasn't working properly. Sad. I turned to the broom :( In frustration I considered buying a vacuum cleaner. From pretty expensive to super cheap. I know vacuum cleaners and I knew it would be a matter of time before they all became almost useless. All these bagless days Stuff that puts me off. I clean my house and mine sometimes so I have a lot of experience with vacuums and I have strong preferences. At least I got my Oreck almost three years before the problems started so I thought maybe I would just buy a new Oreck BUT THEN while looking I came up with something MAYBE - just maybe - although my roller and belt looked fine according to the Oreck booklet maybe it still needs a new brush Maybe it was just at the moment when it was still above par (which means the bristles can grab things) but wasn't as good as it could be (hence less effective), it works in my vacuum cleaner, S I'll verse it search. via the brand website. In fact, a new vacuum cleaner would cost about the same. It took me a while to find a brush and belt that works for my vacuum here. Many sellers do not have a clear description or clear photos. I knew what my roller brush looked like, so I knew what to look for, even if the other information wasn't entirely clear. Which brought me to this seller. Looks like my brushes! So. 2 brushes, 6 belts. <$20 Take my money! The brushes are 11.25 inches long, the same as my factory brush roll. The dimensions include the entire length. Upon arrival it was quick. I decided to take apart the underside of the striker bar one more time so I could install my new roller brush. If you have not already done so: -- unplug the vacuum cleaner, -- turn it over to gain access to the base. Insert a new brush. -- pull out the belt, -- insert a new belt (it was very easy for me, without having to "pull" -- very easy), -- put the plate back in, -- put in the screws. - Plug in and test the vacuum cleaner. MY FUNCTIONS! As expected, it sucks up dirt, hair and fur. Choose him carefully. I could see the carpet completely. He was colorful again! While I'm not exactly sure if it was just a brush, just a belt, or a combination of both, I'm glad I swapped them both out. I suspect it was a roller brush. My Oreck XL display is GOOD NEW AGAIN. I am very satisfied as this is my favorite vacuum cleaner. It just suits our family considering we have a lot of bare floors and low-pile carpets. This is one of the few racks that can raise a bare floor without a special mount and without spitting out dirt. If I have the motivation to get into corners, I use a broom or a long-handled rag or an Oreck Mini with a hose. Anyway I'm SO HAPPY I tried this product and now I don't have to worry about buying another vacuum cleaner. Even if your brush/belt looks perfectly fine, it could be the same as mine and just old enough to be replaced with new ones. Thought it might be worth a try and I'm so glad I bought this. I hope this works for you, I hope this solves your problems and since I'm so damn happy I'm happy to give a full review.
