Main floor brush does not spin, but suction is present; LED on nozzle may still light.

Safety: Turn OFF the vacuum and remove the battery.

Clear and inspect brush:

• Remove the brush roller from the motorized floor nozzle.
• Clean off all hair and debris from the roller and end caps.
• Check for a broken or slipped drive belt (if your Gorenje model uses one).

Reinstall the brush and test. If the roller still does not spin and you can hear no motor noise in the nozzle, the brush motor or internal wiring is likely faulty and the nozzle assembly should be replaced.
