Power nozzle suddenly stopped working (no power or

Hello. Check out your reset button located on the top of the power nozzle. It is either black or red. Turn the cleaner on, and while running, push in the reset. Voila! It should be working again. The reset is put in the vac to protect your power nozzle motor. You have a geared belt that is driven by a circuit breaker protected motor. This way, if there is an overload on it, it will shut off, allowing you to clear it and reset it. I hope this helps! Have a good day.
