Brushroll starts then stops after a few seconds, F2 error appears, often on thick carpets.

Safety first: Turn OFF and remove the battery before working on the nozzle.

• Clean the brushroll thoroughly: Remove the brushroll and clear all hair, threads, and debris from bristles and end caps.
• Check for damage: Inspect the brushroll for warped sections or melted plastic. Replace if damaged.
• Test on hard floor: Reassemble and test the vacuum on a hard floor surface. If F2 does not appear on hard floors but does on thick carpets, the load may be too high for the motor.
• Use lower power mode: On very thick carpets, use a lower suction setting or a non-motorized tool if available.
• Replace nozzle if needed: If F2 occurs even on hard floors with a clean brushroll, the brush motor or nozzle PCB is likely failing and the entire nozzle assembly may need replacement.
