I bought a motorized floor nozzle for a rocket to replace it. On my previous one, the brush roller stopped spinning. There were no problems with the purchased electric floor nozzle. However, it continues to stall (the brush stops). If you are facing a similar problem and have to choose between replacement parts and a new vacuum cleaner, in my experience you may need a new vacuum cleaner. I don't think it's the seller's fault. I wanted to try to reduce waste by getting more life out of my vacuum cleaner, but I didn't achieve that goal.
