Common Causes and Solutions for a Non-Spinning Brush Roll
Several factors can cause your Shark Navigator Lift-Away NV351’s brush roll to stop spinning. Here’s a breakdown of the most common culprits and how to fix them:
1. Check for Blockages
The most frequent cause of a non-spinning brush roll is an obstruction. Hair, string, and debris can easily wrap around the brush roll, preventing it from turning freely.
Solution:
- Unplug the Vacuum: Always disconnect the vacuum from the power outlet before performing any maintenance.
- Inspect the Brush Roll: Carefully examine the brush roll for any visible obstructions.
- Remove Debris: Use scissors or a seam ripper to carefully cut away any tangled hair, string, or debris. Be careful not to damage the bristles.
- Check the Brush Roll Housing: Inspect the area around the brush roll for any trapped debris.
- Reassemble and Test: Reassemble the vacuum and test the brush roll.
2. Reset the Motor
The Shark Navigator NV351 has a thermal protector that can shut off the brush roll motor if it overheats. This is a safety feature to prevent damage to the motor.
Solution:
- Unplug the Vacuum: Disconnect the vacuum from the power outlet.
- Allow to Cool: Let the vacuum cool down for at least 30 minutes. This allows the thermal protector to reset.
- Check for Blockages (Again): While waiting, double-check for any blockages in the brush roll or hose.
- Plug In and Test: Plug the vacuum back in and test the brush roll.
3. Inspect the Belt
The brush roll is driven by a belt that can stretch, break, or slip over time. A worn or damaged belt will prevent the brush roll from spinning.
Solution:
- Access the Brush Roll: Depending on your model, you may need to remove a cover or plate to access the brush roll and belt.
- Inspect the Belt: Check the belt for any signs of wear, damage, or breakage.
- Replace the Belt: If the belt is damaged, replace it with a new one. Refer to your vacuum’s manual for the correct replacement belt.
- Reassemble and Test: Reassemble the vacuum and test the brush roll.
4. Check the Brush Roll Motor
In rare cases, the brush roll motor itself may be faulty. This is more likely to occur in older vacuums or those that have been heavily used.
Solution:
- Test the Motor (Advanced): This requires some electrical knowledge. Use a multimeter to test the motor for continuity. If there is no continuity, the motor is likely faulty.
- Consider Professional Repair: Replacing the motor is a more complex repair. Consider taking your vacuum to a qualified repair technician.
5. Examine the Hose and Airway
A blockage in the hose or airway can reduce suction and prevent the brush roll from spinning properly, especially if the vacuum relies on airflow to assist the brush roll motor.
Solution:
- Detach the Hose: Remove the hose from the vacuum body and the cleaning head.
- Inspect for Blockages: Look through the hose for any obstructions.
- Clear Blockages: Use a broom handle or similar tool to dislodge any blockages.
- Check the Airway: Inspect the airway between the hose and the dust cup for any obstructions.
- Reassemble and Test: Reassemble the vacuum and test the brush roll.
6. Confirm Proper Assembly
Sometimes, the brush roll may not spin simply because the vacuum is not assembled correctly after cleaning or maintenance.
Solution:
- Refer to the Manual: Consult your Shark Navigator NV351’s manual to ensure all parts are correctly assembled.
- Check Connections: Make sure all connections are secure and properly aligned.
- Test Again: Once you’ve confirmed proper assembly, test the brush roll again.
Tools and Materials
- Screwdrivers (Phillips head and flathead)
- Scissors or seam ripper
- Replacement belt (if needed)
- Multimeter (optional, for testing the motor)
- Broom handle or similar tool (for clearing hose blockages)
Preparation Steps
- Read the Manual: Familiarize yourself with your Shark Navigator NV351’s manual for specific instructions and safety information.
- Gather Tools: Collect all the necessary tools and materials before you begin.
- Clear Workspace: Ensure you have a clean and well-lit workspace.
- Unplug Vacuum: Always disconnect the vacuum from the power outlet before performing any maintenance.
Troubleshooting Guide
| Problem | Possible Cause(s) | Solution(s) |
|---|---|---|
| Brush roll not spinning at all | Blockage, tripped thermal protector | Remove blockages, allow vacuum to cool down and reset |
| Brush roll spins weakly | Worn belt, partial blockage | Replace belt, thoroughly check for and remove any blockages |
| Brush roll stops after a few seconds | Overheating, faulty motor | Allow to cool, check for blockages, consider professional motor repair/replacement |

Pro Tips
- Regular Cleaning: Regularly clean the brush roll to prevent buildup and tangles.
- Belt Maintenance: Inspect the belt regularly and replace it as needed.
- Avoid Overloading: Avoid vacuuming large amounts of debris at once, as this can strain the motor and belt.
- Use Correct Settings: Use the appropriate settings for different floor types to optimize performance and prevent damage.
- Check for Firmware Updates: Keep an eye on the manufacturer’s website for firmware updates that may improve performance.
Alternatives/Variations
- Deep Cleaning: For heavily soiled carpets, consider using a carpet cleaner with a rotating brush.
- Specialized Tools: Use specialized tools like upholstery attachments for cleaning furniture and tight spaces.
- Professional Cleaning: For stubborn problems, consider hiring a professional cleaning service.
- Upgrading: If your vacuum is old or frequently malfunctioning, consider upgrading to a newer model with improved features and reliability.
FAQ Section
Why is my Shark vacuum brush roll not spinning even after I cleaned it?
Even after cleaning, small debris or tightly wound hair might still be obstructing the brush roll’s movement. Double-check for any remaining obstructions and ensure the brush roll can spin freely by hand. Also, inspect the belt for wear or damage, as a worn belt can slip and prevent the brush roll from spinning effectively.
How often should I replace the brush roll belt on my Shark Navigator NV351?
The brush roll belt’s lifespan depends on usage, but it’s generally recommended to inspect it every 6 months and replace it every 12-18 months, or sooner if you notice signs of wear, stretching, or cracking. Regular maintenance can extend its life, but replacement is necessary for optimal performance.
Can I use my Shark Navigator NV351 without the brush roll spinning?
While you can technically use the vacuum without the brush roll spinning, you won’t achieve optimal cleaning performance, especially on carpets and rugs. The brush roll is designed to agitate fibers and lift dirt and debris, so without it, the vacuum will primarily rely on suction, which may not be sufficient for thorough cleaning.
What does the brush roll indicator light on my Shark vacuum mean?
The brush roll indicator light provides information about the brush roll’s status. A green light typically indicates normal operation, while a red light usually signals a problem, such as a blockage or the brush roll being turned off. Refer to your vacuum’s manual for specific interpretations of the indicator light colors and patterns.
Is there a reset button for the brush roll on the Shark Navigator NV351?
The Shark Navigator NV351 doesn’t have a specific reset button for the brush roll. However, if the brush roll stops spinning due to overheating, unplugging the vacuum and allowing it to cool down for about 30 minutes will usually reset the thermal protector and restore functionality.
How do I know if my Shark vacuum motor is failing?
Signs of a failing motor include a lack of power, unusual noises (such as grinding or whining), intermittent operation, or a burning smell. If you notice these symptoms, it’s best to consult a qualified repair technician or consider replacing the vacuum.
