They worked great in my AS1001 Eureka canister vacuum. I've noticed that the brush just doesn't spin like it used to. After disassembly, the old belt seemed intact, although aged. I took a chance and decided to just replace it with new straps. Comparing the new to the old, it was pretty obvious that they were just old and overstretched. Replaced it and my old 7+ year old vacuum cleaner came back to life! The rotating brush no longer stuck to thick carpet like it used to and was like new again. It would be great to collect all the dog hair again. At the moment it works great. I'll see how they hold up over time. So far so good for now. I recommend!
