Vacuum shows C06 and the brush head does not spin, though suction may still work.

Safety first: Turn OFF the vacuum and remove the battery before working on the brush head.

• Remove the brush head: Detach the motorized floor head from the wand.
• Clean the brush roll: Unlock and remove the brush roll. Use scissors to carefully cut away hair, threads, and debris from the roller and end caps.
• Check bearings: Spin the brush roll by hand. It should rotate freely. If it feels rough or seized, the brush roll assembly should be replaced.
• Inspect for obstructions: Look inside the brush head housing for lodged objects blocking the roller.
• Reassemble and test: Reinstall the brush roll, attach the head, and test on low power. If C06 no longer appears, the jam was cleared.
• If C06 returns immediately with a clean, free-spinning roller: The brush motor or internal PCB is likely faulty. Replace the complete motorized floor head or have it serviced.
