Why the Brush Bar Stops: Common Culprits
The Dyson V11 High Torque Cleaner Head relies on a delicate balance of mechanical and electrical components. Common issues include:
– Blocked brush bar: Hair, string, or debris the roller, restricting movement.
– Worn or damaged brush bar: Frayed bristles or cracks reduce effectiveness.
– Motor failure: Internal motor defects, especially in V11 High Torque models.

– Frozen bearings: Seen in SV11 models, preventing rotation.
– Low battery: Inadequate power in eco/auto modes.
– Airflow blockages: Clogged filters or hoses disrupting suction.
Step-by-Step Troubleshooting Guide
1. Check for Blockages
- Turn off and unplug the vacuum.
- Remove the brush bar using a coin or flathead screwdriver (rotate counterclockwise to unlock).
- Use needle-nose pliers to clear tangled hair or debris from the roller and housing.
- Inspect gear ends and clean thoroughly.
If the brush bar is severely damaged or worn, consider replacing it after cleaning to ensure optimal performance.

3. Verify Battery and Power
- Fully charge the battery. Low voltage in eco/auto modes can disable motorized heads.
If the battery isn’t holding a charge, it might be time to consider replacing it to ensure consistent power to the cleaner head.

4. Inspect Wand and Hose Connections
- Detach the wand and shine a flashlight into the tube to spot obstructions.
- Clear blockages in the hose or filter to restore airflow.
5. Swap Cleaner Heads
- Test with a Soft Roller head. If it works, the issue is isolated to the High Torque head.
6. Direct Connection Test
- Attach the High Torque head directly to the bin, bypassing the wand. If it spins, the wand’s connection is faulty.
