Why isn't your shark robot vacuum spinning

When your Shark Robot’s side brush isn’t spinning, there are usually a few things happening that we’ve researched before. 

  • Most of the time, pet hair and dirt get stuck in the brush, causing it to stop moving. It often appears that the motor that moves the brush can also be the problem. The brush will not rotate if it is broken or not working properly. Vacuum sensors can also cause problems. If they don’t work properly, they may not rotate the brush as it should.
  • Sometimes, a low battery can be the culprit. If the vacuum doesn’t have enough power, it might not spin the side brush properly. Other things like the tension on the brush, the brush belt, clogged (Shark robot vacuum) air filters, or an overloaded dustbin also mess with the brush’s spinning.
  • Occasionally, software or firmware problems in the vacuum affect the side brush. Lastly, if the side brush itself is worn out, it won’t grip the floor properly. 

So, when you face this problem, it is better to check these things to understand its cause. But below, we will tell you some steps for some solutions; let’s know.

How to Resolve the Issue of My Vacuum Brush Not Spinning

Remove the hair 

Start with Get Rid Of The Hair, turn off your hoover and unplug it. Next, you’ll need to remove a cover or access panel to get to the brush area.

I hope you can do this easily. So, let’s go to the next step.

Check the Shark Robot Motor

The motor is an important part that makes the brush spin. If something is wrong, the brush won’t turn. Access the motor, it is typically located near the brush. Check for damage or signs of burning that you can see. If the motor is broken, you need to get a new one. Find out how to get a new motor for your vacuum by looking at the user instructions or the manufacturer’s website.

Use WD40

If the brush does not rotate smoothly even after removing the hair, it is assumed that it is due to rust or hardening of the moving parts of the brush. In such cases, you can apply a small amount of WD40 Spray or similar lubricant to the brush bearings or pivot points.

You may be wondering what other similar lubricants there are. Actually, there are many on the market, such as:

  • 3-In-One Oil,
  • Silicone Lubricant Spray,
  • White Lithium Grease or
  • Machine Oil

These can usually be used in your vacuum. However, we suggest that you follow the product instructions and avoid over-application. 

Remember that excess Oil helps to accumulate dust and debris in the future.

Fully Charge

Low battery power can cause the brush to stop spinning. Make sure your cleaning robot is fully charged before using it. Plug it into the charger and allow it to charge for the recommended duration. But you should charge it for 2-3 hours. However, once charged, try using the vacuum again to see if the brush spins correctly.
