Compatibility
This brush roll is compatible with Dyson DC07 and DC14 series upright vacuum cleaners that feature a clutch mechanism. Please verify your vacuum model before installation.
Installation Guide
Proper installation of the brush roll is crucial for effective vacuum operation. Always ensure the vacuum cleaner is unplugged from the power outlet before beginning any installation or maintenance.
- Safety First: Unplug your Dyson DC07 or DC14 vacuum cleaner from the electrical outlet.
- Access the Brush Bar: Lay the vacuum cleaner on its side to access the brush bar housing. Depending on your specific model, you may need to remove a soleplate or cover. Refer to your vacuum's original manual for precise instructions on accessing the brush bar.
- Remove Old Brush Roll: Carefully unclip or unscrew the retaining clips/screws that hold the old brush roll in place. Gently pull out the worn or damaged brush roll. Note the orientation of the old brush roll for correct installation of the new one.
- Inspect Components: While the brush roll is removed, inspect the belt for wear or damage. Replace the belt if necessary. Clean any accumulated debris from the brush bar housing.
- Install New Brush Roll: Align the new Dyson brush roll (part # 10-3400-25) with the belt and the brush bar housing. Ensure the ends of the brush roll fit securely into their respective slots. The brush roll should spin freely by hand once installed.
- Secure Brush Roll: Reattach any retaining clips or screws that were removed. Ensure all components are securely fastened.
- Reassemble Vacuum: Replace the soleplate or cover, if applicable.
- Test Operation: Plug the vacuum cleaner back into the power outlet and test its operation. The brush roll should spin smoothly when the vacuum is turned on.

Operating Considerations
Once installed, the brush roll functions automatically when the vacuum is engaged for carpet cleaning. Ensure the brush roll is free from obstructions for optimal performance. Avoid using the brush roll on hard floors if your vacuum has a brush roll off setting, as this can cause unnecessary wear or damage to both the brush roll and the floor surface.
Maintenance
Regular maintenance extends the life of your brush roll and maintains cleaning efficiency.
- Hair and Fiber Removal: Periodically inspect the brush roll for tangled hair, threads, or fibers. Use scissors or a seam ripper to carefully cut and remove any accumulated debris. Always unplug the vacuum before performing this task.
- Brush Condition Check: Examine the bristles for wear. If bristles are significantly worn down or missing, the brush roll may need replacement to maintain effective cleaning.
- End Cap Inspection: Check the brush roll end caps for any damage or excessive wear. Ensure they are securely in place.
- Belt Inspection: While performing brush roll maintenance, also check the vacuum's drive belt for signs of stretching, cracking, or breakage. A worn belt can prevent the brush roll from spinning correctly.
