I spent $3,000 on a Rainbow vacuum that I really liked and occasionally I lose the cylinder brush and buy a replacement brush. This product looks the same but does not fit and the end of the hose fits. doesn't fit an inch and a half to two inches in place to secure it. What I finally did was put it on the end of the stick and apparently after a few times it stretched enough to be usable and now it works fine but they should come up with a little guide about it for you says how you condition it. . 😆😉
