While the orange part of the cleaning roller fits properly in the nozzle of the vacuum cleaner, the bristle part of the roller does not fit properly in the vacuum cleaner. It must be forced into position and even then the brushroll access cover will continue to open. In the short time it was stuffed into my vacuum to try it out, it damaged the part of the vacuum it whirls out of. His oversize started drilling bits of pivot points. Basically I needed a new part to clean the orange roller as I can just brush and remove the bristle part so it's good enough for my purposes but anyone who needs a new bristle part should know it's not for the vacuum cleaner for which it is designed.
