Common Causes and Solutions for a Non-Spinning Brush Roll
Several factors can contribute to a brush roll that won’t spin. We’ll cover the most common culprits and how to address them:
1. Check for Blockages
The most frequent cause of a brush not spinning is a blockage. Hair, string, and debris can easily get tangled around the brush roll, preventing it from rotating freely.
How to check and clear blockages:
- Turn off and unplug the vacuum: Always ensure the vacuum is turned off and unplugged from the power outlet before performing any maintenance or troubleshooting.
- Inspect the brush roll: Remove the brush roll cover (usually held in place by a few screws or clips). Carefully examine the brush roll for any visible obstructions.
- Remove debris: Use scissors or a seam ripper to carefully cut away any hair, string, or fibers wrapped around the brush roll. Be gentle to avoid damaging the bristles.
- Check the airways: Also, inspect the airways and hose connections for any blockages. Remove any debris you find.
- Reassemble and test: Replace the brush roll cover and turn on the vacuum to see if the brush roll is now spinning.
2. Reset the Brush Roll
The Shark NV752 features a brush roll reset function that can sometimes resolve issues.
How to reset the brush roll:
- Turn off and unplug the vacuum: As always, safety first.
- Locate the reset button: The reset button is usually located on the vacuum head. Consult your owner’s manual if you can’t find it.
- Press and hold: Press and hold the reset button for a few seconds (usually 3-5 seconds).
- Test the brush roll: Plug the vacuum back in and turn it on to see if the brush roll is now functioning.
3. Check the Drive Belt
The drive belt connects the motor to the brush roll. If the belt is broken or stretched, the brush roll won’t spin.
How to check the drive belt:
- Turn off and unplug the vacuum: Safety first.
- Access the brush roll compartment: Remove the brush roll cover and brush roll.
- Inspect the belt: Examine the drive belt for any signs of damage, such as cracks, tears, or excessive stretching.
- Replace if necessary: If the belt is damaged, you’ll need to replace it. You can purchase a replacement belt from the Shark website or a local appliance parts store. Refer to your owner’s manual for the correct belt model.
- Reassemble and test: Install the new belt, reassemble the vacuum, and test to see if the brush roll is now spinning.
4. Examine the Motor
Although less common, a faulty motor can also be the reason for a non-spinning brush roll.
How to check the motor:
- Listen for motor sounds: Turn on the vacuum and listen closely to the motor. If you hear unusual noises or no sound, the motor may be failing.
- Professional inspection: If you suspect a motor issue, it’s best to have the vacuum inspected by a qualified technician. Replacing a motor can be complex and may require specialized tools.
5. Check the Brush Roll Sensor
Some Shark vacuums have a sensor that detects if the brush roll is obstructed. If the sensor is faulty, it may prevent the brush roll from spinning even if there’s no actual blockage.
How to check the sensor:
- Locate the sensor: Consult your owner’s manual to find the location of the brush roll sensor.
- Clean the sensor: Gently clean the sensor with a soft, dry cloth.
- Test the vacuum: Turn on the vacuum to see if cleaning the sensor has resolved the issue. If not, the sensor may need to be replaced, which typically requires professional service.
6. Overheating
Sometimes, the vacuum cleaner might overheat, causing the brush roll to stop spinning as a protective measure.
How to address overheating:
- Turn off and unplug the vacuum: Allow the vacuum to cool down for at least 30 minutes.
- Check for blockages: Ensure that there are no blockages in the hose, filters, or brush roll area that could cause the motor to overwork and overheat.
- Clean the filters: Dirty filters can restrict airflow and cause the motor to overheat. Clean or replace the filters as recommended in the owner’s manual.
- Restart the vacuum: After cooling down and clearing any obstructions, plug in and turn on the vacuum to see if the brush roll is functioning again.

What should I do if the brush roll is still not spinning after trying these steps?
If the brush roll continues to not spin after attempting these troubleshooting steps, there might be a more significant issue with the motor or electrical components. In such cases, it is best to consult with a professional repair service or contact Shark customer support for further assistance.
How do I prevent hair from tangling around the brush roll?
To minimize hair tangling, regularly clean the brush roll after each use. Consider using a tool specifically designed to cut and remove tangled hair, such as a seam ripper or small scissors.
