Vacuum runs but the motorized cleaner head brush bar does not spin; some models show a brush bar icon or red light on the head.

Safety: Turn off and remove the battery. Never work on the brush bar while the vacuum is powered.

• Remove cleaner head: Detach the motorized head from the wand and main body.
• Clear jams: Open the end cap (usually with a coin) and remove the brush bar. Cut away hair, string, and fibers with scissors, avoiding the bristles.
• Inspect bearings and belt: Spin the brush bar by hand; it should rotate freely. On heads with belts, check for a snapped or stretched belt and replace if necessary.
• Check electrical contacts: Inspect the metal contacts on the neck of the cleaner head and the wand for dirt or damage. Clean gently with a dry cloth.
• Test with another head/wand: If available, connect a different motorized head or wand. If the alternate head works, replace the faulty cleaner head. If none work, the issue may be in the wand wiring or main body PCB.
