Why Is My Shark Vacuum Brush Not Spinning – Solve Yourself

The brush roll is a big part of why Shark vacuums are known for how well they clean, which is why they are so popular. This moving brush, also called a brush bar or beater bar, is an integral part of the vacuum. It helps loosen dirt, dust, and other debris from surfaces like rugs and hard floors so the vacuum can pick it up.

When the cleaner is in use, the brush roll spins quickly, which moves the area being cleaned around. This movement helps loosen particles stuck in the carpet strands or in the cracks of hard floors. The vacuum picks up the loose dirt as the brush roll moves over the surface, leaving your floors clean and fresh.

But when your Shark vacuum’s brush roll isn’t turning, it makes cleaning much less effective. This problem needs to be fixed right away if you want your Shark vacuum to keep working well and getting the great results for which it is known. Do you know how to fix it? Well, if you don’t know, stay with us! Because in this article, we will tell you in detail why it happens, the signs, and how to fix it. So, let’s start!

First, you should know why your shark vacuum brush is in Spain.

Why Does Your Shark Vacuum Brush Spin? 

Why Does Your Shark Vacuum Brush Spin

Your Shark vacuum brush spins because it helps pick up dirt and debris from your floors better. When you push the vacuum, the spinning brush scrubs the carpet and loosens up the dirt. Then, it sucks up the loosened dirt into the vacuum, making your floors cleaner. So, the spinning brush is like a cleaning helper for your vacuum!

Next, you will know four signs that your vacuum is not spinning.

What Are The Signs Of A Shark Vacuum Brush Not Spinning – (4 Symptoms)

  • One sign is when the roll (vacuum) warning light goes from green to red. If you see this, it indicates that the brush roll might not work right.
  • You might find that your vacuum stops picking up dirt and other things like it should. It has a brush problem if it leaves dirt behind or doesn’t clean as well as it used to.
  • It might seem like your vacuum is losing power, making it less good at cleaning. This could be because the brush doesn’t spin right.
  • When the brush bar itself stops turning, this is the most clear sign. When the vacuum is going, if you can see that the brush isn’t moving, this is a clear sign that something is wrong.

If you notice these signs, you know you are going to have a problem. Now let’s know some reasons why the vacuum brush is not spinning.

7 Reasons Shark Vacuum Brush Not Spinning

Below are the 7 reasons for not spinning the shark vacuum brush. Also provided is an infographic.

7 Reasons Shark Vacuum Brush Not Spinning

Brushroll Switch Position

The brush roll in a Shark vacuum can typically be turned on and off using a switch located on the vacuum’s handle or body. If this switch is accidentally bumped or set to the “off” position, it will prevent the brush roll from spinning.

Blockages and Debris

Blockages and debris can stop your vacuum brush from spinning. When things like hair or small objects get stuck in the brush or block the airflow, it makes the brush jam or slow down. This can lead to your vacuum not cleaning well or losing power. 

The belt that is worn out or broken

In Shark vacuums, the brush roll (issus) spins because of a belt. If the belt gets old or broken, it won’t be able to turn the brush roll as well. If a belt is worn out or broken, it will be loose or slack, show signs of wear, or smell like burned rubber.

Motor Issues

The brush roll in your Shark vacuum gets its (suction) power from the motor. If the motor has problems, like not having enough power or getting too hot, the brush roll might not spin. 

Clogged Airflow

Proper airflow is essential for the brush roll to function correctly. When the vacuum’s airflow is obstructed due to clogs in the hoses, filters, or air pathways, it can cause the brush roll to stop spinning. 


Shark vacuums have built-in safety measures that keep them from getting too hot. If the vacuum’s temperature gets too high, the brush roll turns off to prevent damage. It can get too hot if the filters are stuck or if the vacuum is used for a long time without stopping.

Vacuum Height Adjustment

The height setting on your Shark cleaner is very important if you want the brush roll to work as well as possible. If the vacuum height is set too low for the type of floor you’re cleaning, the brush roll might stop or not spin the way it should. On the other hand, if it’s set too high, it might not touch the floor.

  • Examine the brush roll and air pathways for blockages. Turn off the vacuum, unplug it, and clean the brush roll and the area around it of any dust or knotted hair.
  • Inspect the condition of the belt. It needs replacement if it’s loose, damaged, or showing signs of wear. Refer to your vacuum’s manual for instructions on accessing and replacing the belt.
  • If you suspect motor issues, such as a lack of power or overheating, it’s advisable to consult a professional technician.
  • To keep your vacuum from getting too hot, make sure the filters are clean and use them according to the instructions. As well as taking breaks as needed to let the motor cool.
