- Maneuverability: The nozzle features a swivel neck for easy maneuverability around furniture and obstacles.

Maintenance
Regular maintenance of your Dyson Nozzle Assembly ensures consistent performance and extends its lifespan.
- Brush Bar Inspection: Periodically inspect the brush bar for tangled hair, threads, or debris. Excessive build-up can reduce cleaning effectiveness and strain the motor.
- Cleaning the Brush Bar: To clean, detach the nozzle from the vacuum. Use scissors or a seam ripper to carefully cut away any tangled material from the brush bar. Avoid pulling forcefully, as this can damage the bristles.
- Check for Obstructions: Ensure the air pathways within the nozzle are clear of any blockages.
- Exterior Cleaning: Wipe the exterior of the nozzle with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
Troubleshooting
If you encounter issues with your Dyson Nozzle Assembly, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Brush bar not spinning or spinning slowly | Tangled debris, obstruction, or worn components. | Clean the brush bar of any tangled hair or debris. Check for blockages in the nozzle's air path. If the issue persists, the internal mechanism may require professional inspection or replacement. |
| Reduced suction at the nozzle | Blockage in the nozzle, wand, or hose; improper attachment. | Ensure the nozzle is securely attached to the vacuum. Check the nozzle, wand, and hose for any obstructions and remove them. Verify the vacuum's dust bin is not full and filters are clean. |
