My 12 year old Dyson had difficulty pushing and seemed to struggle with debris. While I was happy with the replacement at this point, I figured it was worth playing a little to see if changing the belts would keep it going. It came with a clutch strap and a brush strap. The brush belt can be replaced by removing the clutch assembly. My straps didn't snap, but they definitely stretched. The demolition wasn't easy, but it wasn't terrible. Changing the brush belt can be tricky and I can see where this tool will help, but luckily I've done a lot of deadlifts in my time so I have strong arms. After assembly, the vacuum cleaner worked perfectly. I hope this buys him a few more years of life. I sincerely recommend this product.
