Common Causes and How to Identify Them
Brush Bar Blockages
A lack of brush bar movement is often due to hair, string, or debris缠绕 the roller. Turn off and unplug the vacuum, then remove the motorhead cover to inspect. If the brush bar resists manual spinning, tangled fibers are likely the culprit. Use scissors to cut away obstructions and a cloth to wipe away dust. Don’t forget to check the end caps for hidden debris.
Worn or Broken Drive Belts
The drive belt connects the motor to the brush bar. If frayed or snapped, the motor spins but fails to turn the roller. Access the belt by removing the brush bar, then check for visible damage. Replacing it requires aligning the new belt around the motor and brush bar pulleys.
Motor and Electrical Issues
Faulty motors or electrical connections can silence the brush head. Use a multimeter to test motor continuity—if no power registers, replacement may be necessary. Dirty contacts between the canister and motor unit also disrupt function. Clean them with rubbing alcohol and a cotton swab, ensuring they dry completely before reassembly.
If testing reveals that your Dyson’s motor has failed, replacing it is often the most effective solution. Ensure you select a motor that is compatible with your specific Dyson model to guarantee proper fit and performance.

Gear and Bearing Problems
The gear mechanism driving the brush bar can accumulate dirt, preventing motion. Disassemble the brush head and inspect the gear. If it resists manual rotation, remove obstructions with a screwdriver. Worn bearings may require lubrication or replacement to restore smooth operation.

Preventive Maintenance Tips
Regular Cleaning Routines
After every few uses, inspect and clean the brush bar to prevent hair and debris buildup. This simple habit avoids clogs that strain the motor.
Monitoring Wear and Tear
Check the drive belt and bearings periodically. Replace the belt if fraying appears, and lubricate or replace damaged bearings to maintain efficiency.
Proper Storage Practices
Store the vacuum upright to prevent hose kinks and keep the motorhead free of dust. Avoid overfilling the dust bin, which can overload the motor.
