Check for Blockages in the Brush Roll
![]()
The most frequent reason for a Shark NV601 brush not spinning is a blockage. Hair, threads, and large debris can easily get tangled around the brush roll, preventing it from rotating freely.
- Turn off and unplug the vacuum: Safety first! Always disconnect the vacuum from the power outlet before performing any maintenance.
- Locate the brush roll access: On the Shark NV601, the brush roll is located on the vacuum head. You may need to use a screwdriver to open the brush roll cover, depending on your model.
- Remove the brush roll: Carefully lift the brush roll out of the vacuum head.
- Clear any visible obstructions: Use scissors or a seam ripper to cut away any tangled hair, threads, or debris wrapped around the brush roll. Pay close attention to the ends of the brush roll, where obstructions often accumulate.
- Inspect the brush roll housing: Check for any blockages inside the brush roll housing as well. Remove any debris that may be hindering the brush roll’s movement.
- Reinstall the brush roll: Once the brush roll and housing are clear, reinstall the brush roll and secure the cover.
Inspect the Hose and Nozzle for Obstructions

Even if the brush roll itself is clear, a blockage in the hose or nozzle can also prevent it from spinning. This is because the vacuum needs proper airflow to operate the brush roll effectively.
- Detach the hose: Disconnect the hose from both the vacuum body and the vacuum head.
- Visually inspect the hose: Look through the hose for any visible obstructions.
- Use a long object to dislodge blockages: If you see any blockages, use a broom handle or similar long object to gently push them out. Be careful not to puncture or damage the hose.
- Check the nozzle: Examine the nozzle opening on the vacuum head for any obstructions. Remove any debris that you find.
- Reassemble the vacuum: Once the hose and nozzle are clear, reattach the hose to the vacuum body and vacuum head.
Reset the Motor Thermostat
The Shark NV601 has a motor thermostat that can trip if the vacuum overheats due to a blockage or other issue. Resetting the thermostat can sometimes resolve the brush roll issue.
- Unplug the vacuum: Disconnect the vacuum from the power outlet.
- Allow the vacuum to cool down: Let the vacuum sit for at least 30-60 minutes to allow the motor to cool completely.
- Check and clear any blockages: While the vacuum is cooling, double-check for any remaining blockages in the brush roll, hose, or nozzle.
- Plug the vacuum back in: After the cool-down period, plug the vacuum back into the power outlet.
- Test the vacuum: Turn on the vacuum and check if the brush roll is now spinning.
Check the Brush Roll Motor
If the above steps don’t work, the issue might be a faulty brush roll motor.
- Listen for motor sounds: When you turn on the vacuum, listen closely to see if you can hear the brush roll motor attempting to spin. If you hear a humming or clicking sound, the motor may be receiving power but is unable to turn the brush roll.
- Check the brush roll motor belt (if applicable): Some Shark NV601 models have a belt that connects the motor to the brush roll. If the belt is broken or loose, the brush roll won’t spin.
- Contact Shark customer support: If you suspect a faulty motor or belt, it’s best to contact Shark customer support for assistance. They can help you diagnose the problem and determine if a repair or replacement is necessary.
Clean the Brush Roll Properly

Regular cleaning is crucial to maintain your Shark NV601’s performance. A clean brush roll spins more efficiently and picks up dirt more effectively.
- Disassemble the brush roll: Remove the brush roll from the vacuum head.
- Remove hair and debris: Use scissors or a seam ripper to carefully cut away any tangled hair, threads, or debris wrapped around the brush roll.
- Wash the brush roll (if possible): Some brush rolls can be washed with mild soap and water. Check your vacuum’s manual for specific instructions.
- Dry the brush roll completely: Before reinstalling the brush roll, make sure it is completely dry to prevent mold or mildew growth.
- Reinstall the brush roll: Once the brush roll is clean and dry, reinstall it in the vacuum head.
Tools and Materials Needed
- Screwdriver (if required to access brush roll)

FAQ Section
Why is my Shark vacuum losing suction and the brush isn’t spinning?
Reduced suction often accompanies a brush roll that won’t spin, indicating a significant blockage. Clear all obstructions from the brush roll, hose, filters, and dustbin. A full dustbin or dirty filter restricts airflow, further impacting suction and brush roll function.
How do I prevent hair from tangling around my Shark NV601 brush roll?
Regular maintenance is key. Clean the brush roll frequently, cutting away tangled hair instead of pulling it. Consider using a vacuum with a self-cleaning brush roll feature for reduced maintenance. Empty the dustbin regularly to maintain optimal suction and prevent hair from being forced around the brush roll.
Can I use my Shark NV601 on hardwood floors if the brush roll is spinning?
Yes, but with caution. Ensure your vacuum has a hardwood floor setting that either stops the brush roll from spinning or significantly reduces its speed. Using a spinning brush roll on hardwood can cause scratches and damage over time. If your model lacks such a setting, consider using a different attachment designed for hardwood floors.
What does it mean if my Shark vacuum pulsates and the brush roll stops intermittently?
Pulsating suction and intermittent brush roll stops often signal a partial blockage or overheating. Check for obstructions in the hose, nozzle, and brush roll. Clean the filters and empty the dustbin. If the issue persists, allow the vacuum to cool down completely, as the motor may be overheating due to restricted airflow.
How often should I replace the brush roll on my Shark NV601?
The lifespan of your brush roll depends on usage and maintenance. Inspect the brush roll regularly for wear and tear, such as damaged bristles or a misshapen roller. Replace the brush roll every 6-12 months, or sooner if you notice a decline in cleaning performance.
Is it normal for the Shark NV601 brush roll to stop spinning on thick carpets?
Some Shark models have a safety feature that stops the brush roll on very thick carpets to prevent damage to the carpet or the vacuum. Check your vacuum’s manual to see if this feature applies to your model. If the brush roll consistently stops on all carpets, refer to the troubleshooting steps above.
Tips, Warnings, and Best Practices
- Warning: Always unplug the vacuum before performing any maintenance to avoid electric shock.
- Tip: Use a flashlight to thoroughly inspect the hose and nozzle for hidden blockages.
- Best Practice: Empty the dustbin and clean the filters after each use to maintain optimal performance.
- Tip: When cutting tangled hair from the brush roll, be careful not to damage the bristles.
- Warning: Never submerge the vacuum body in water or other liquids.
