Signs That Your Shark Vacuum Brush Has Stopped Working
There are several reasons why your Shark vacuum brush has stopped working or spinning. But first, let’s take a look at the signs that your Shark roller brush is not working.
- In some Shark models, there’s a roll indicator light to tell if the brush is functioning or not. If the light is red or no light at all, there’s an issue with the roller brush.
- The vacuum just stopped picking up dirt and debris or the suction lacks the usual power.
- The brush bar has stopped working or spinning.
- The vacuum spits out dirt and debris even when not in use. Dirt and debris are left on the floor when you lift the vacuum.
These signs can be frustrating especially when your Shark vacuum just starts regurgitating dirt and debris after vacuuming. So what are the potential causes of this issue? We’ve listed some of the common causes below.

Why is My Shark Vacuum Brush Not Spinning?
Roller Brush Switch is Off
Your Shark vacuum has a roller brush switch aka carpet mode that makes the brush spin. The switch should be toggled to Power and Brushroll mode to make the roller brush spin. Otherwise, the roller will not spin since it’s set to just power or floor mode.
The light indicator should be green when it’s working properly. Also, the brush will only activate when the vacuum is tilted back not when it’s standing upright.
Floor Nozzle is Disengaged
For the roller brush to work, the nozzle must be properly attached. Otherwise, the brush will not spin even if the vacuum has power.
Ensure the nozzle’s tight connection by firmly pressing down on the handle. If you can’t properly engage the nozzle, proceed to unplug the vacuum and disconnect the nozzle. Clear the nozzle of debris and blockages and reconnect the vacuum.
Debris or Hair on the Brush
With continued use, your brush roll will get dirty and accumulate debris or hair. This can cause your Shark brush roll to stop spinning. This is more likely to happen if you don’t regularly clean the brush. Hair is the most common culprit that causes the brush to get stuck.
For hair accumulation on the brush, use a pair of scissors to cut the hair. For a particularly heavy buildup, you should use a razor blade. Just make sure you don’t cut the bristles of the brush bar. For instructions on how to clean the brush roll, refer to our guide below.
In the older models of Shark vacuum cleaners, they use the belt to spin the roller brush. For modern models, they utilize the “tripped” reset systems.
If the belt is broken or worn out, the roller brush will stop spinning. At this point, it is recommended to replace the belt altogether. See our guide below on how to replace a broken brush belt.
Blockage in the Hose or Dust Cap
If the vacuum brush has stopped spinning and there’s no suction power, check if there are blockages in the dust cap or hose. Generally, blockages in the dust cap are easily seen once you have emptied it. So clean and empty the dust cap to see any obstruction.
For checking the hose for blockages, press the quick-release foot pedal and remove the hose. You should be able to see if there’s anything that blocks the hose. Remember, the blockage may not be enough to stop the suction, but it will surely affect how the vacuum sounds while operating.
Troubleshooting Tips for Shark Vacuum Brush Not Spinning Problem
Steps on How to Clean the Brush Roll
The Shark vacuum brush roll needs to be cleaned regularly for optimal performance. Too much debris or hair buildup on the roll will cause the brush to stop spinning. Follow the steps below to clean the brush roll.
Step 1: Unplug the vacuum. Look for three plastic knobs in the brush roll plate and unlock them.
Step 2: Remove the belt. You have the choice of taking out the brush bar or not but for a thorough clean, it’s better to remove the bar.
Step 3: Use a pair of scissors to cut the hair and string that are stuck on the brush. For heavy buildup of hair, you can use a large razor or a stick picker to loosen the tangled hair. Shark does have a hair removal tool that may come with your vacuum.
Step 4: Thoroughly clean the bar because all the hair and string can hamper the vacuum’s suction power.
