Shark Vacuum Brush Not Spinning: 7 Easy Ways To Fix It Now

Shark vacuum cleaners are known to carry powerful suction and have efficient cleaning capabilities.

But despite those capabilities, many users still complain about the brush roll failing to spin. This can quickly become a frustrating issue, especially when it starts affecting the vacuum’s cleaning performance.

The good news is there are several ways to fix a shark vacuum brush that is not spinning. In this guide, we’ll look at some common issues why your brush roll may not be spinning and provide practical solutions to get your vacuum brush spinning again.

Why is Your Shark Vacuum Brush Not Spinning?

Several reasons could prevent your Shark vacuum from spinning. Some of the most common causes include the following:

1. Clogged Brush Roll

A clogged brush roll is one of the most common issues of a Shark vacuum roller brush not spinning. It can become clogged with hair, pet dander, dirt, and debris as you use the vacuum cleaner daily.

If it is not regularly cleaned, it can prevent it from spinning. To fix this problem, you must remove the brush roll and thoroughly clean it.

2. Belt Problem

If your Shark vacuum brush roll is not clogged and still not spinning, it’s likely because you have a broken or worn-out roller belt.

The brush roller belt is responsible for turning or rotating the brush roll, so if it gets broken or worn out, it won’t spin. To determine if the belt is the cause of your brush not spinning, you’ll have to remove the brush roll and inspect the belt for any signs of damage.

3. Clogged Hose or Filter

Another common cause is a clogged filter or hose. If the hose or filter is clogged, the vacuum cannot turn or rotate the brush roll. You’ll have to inspect the filter and hose for clogs to fix the problem.

4. Motor Problem

A malfunctioning motor can prevent your Shark vacuum brush from spinning. If your vacuum’s brush motor is not working properly, it’ll be unable to provide the required power to turn or rotate. To fix the problem, you’ll have to check the motor for any signs of damage.

How to Fix a Shark Vacuum Brush Not Spinning?

If you’re facing issues with your Shark vacuum cleaner’s brush roll not spinning, don’t worry. There are several fixes you can try to get it working again. In this section, we’ll outline some of the most common fixes you can try to solve the problem.

1. Clearing the Brush roll

As you continue using the Shark vacuum cleaner, it can become tangled with hair or other debris over time.

To fix the problem, you can use a knife or scissors to carefully cut through any tangled hair or debris you find. After removing all the impediments, clean the brush roll with a soft-bristled brush or a moist towel.

While cleaning the brush roll, remember to clean the bearings as well. Once it is cleaned, reattach it to the vacuum and test it. Before attempting to clear the brush roll, switch off and disconnect the vacuum.

2. Checking the Drive belt

The brush roll drive belt connects the roller brush to the motor of the vacuum. If your drive belt is stretched out or you have a broken brush belt, the brush roll cannot spin.

To inspect the drive belt, you’ll have to remove the cover and look at the belt. You’ll have to replace the belt if it appears loose or damaged. You can buy a compatible replacement belt from a local vacuum store or manufacturer.

Once the belt has been purchased, replace the old belt with the new one and stretch the new belt over the motor shaft and brush roll. Ensure that the belt is tightened correctly and aligned. Lastly, reattach the brush roll and test the vacuum.

3. Checking the Motor

The vacuum’s motor may be problematic if your brush roll is not spinning.

To inspect the motor, you’ll have to remove the brush roll cover and use a multimeter to test the motor’s continuity.

If, after testing and the motor is faulty, you’ll have to replace it. However, if it’s not faulty but it’s dirty or clogged, then you don’t need to replace it. All you have to do is clean it with compressed air or a soft-bristled brush. Once you clean the motor, reattach it to the vacuum and test it.

4. Checking the Brush roll switch

The switch in a Shark vacuum cleaner turns the brush roll on and off. If the switch starts malfunctioning, the brush roll will be unable to spin.

To inspect the switch, test its continuity using a multimeter. If it fails the continuity test, you must replace the switch.

5. Cleaning the Bearings

Over time, the bearings on the brush roll can become clogged with dirt and debris, which can cause the brush roll to stop spinning.

To clean the bearings, you’ll have to remove and disassemble the brush roll. Once you have done that, use a toothbrush or tweezers to remove dirt or debris accumulated in the bearings. You should also inspect the bearings for signs of wear or damage and, if necessary, replace them.

6. Clearing Clogs in the Vacuum

If your vacuum is clogged, it can prevent air from flowing properly, and when that happens, it’ll cause the Shark vacuum brush roll to stop spinning.

To check for clogs in your vacuum, you’ll have to disconnect the vacuum hose and look for obstructions. While at it, check the dustbin and intake port for blockages or clogs. Use a long, flexible tool like a plumbing snake or coat hanger to clear it out if you find any.

7. Replacing the Brush roll

If nothing seems to be working after trying all the fixes above, it might be time to change the brush roll.

Changing it is essential because, over time, the bristles can become worn out, and that could stop the brush roll from spinning. To replace it, you’ll first have to purchase a replacement and follow the manufacturer’s instructions (repair guide) for installation.

In conclusion, if the brush on your shark vacuum is not spinning, several potential causes and solutions exist.

By cleaning the bearings, checking the drive belt, clearing clogs in the vacuum, checking the motor, and replacing the brush roll if necessary, you can restore your vacuum’s functionality and ensure that it continues to work effectively for years to come.
