When you clean your home and the brush roller stops spinning on your shark vacuum cleaner, it’s easy to panic.
What if it’s broken? Why does the vacuum brush not rotate?
You depend on your vacuum cleaner, so you need to get it up and run again as soon as possible. Hopefully, without having to pay for expensive repairs.
In this guide, we will tell you about various reasons the brush roller has stopped. And what you can do to fix it in your own home. From simple maintenance to damage and breakdowns, we have you covered.
The shark vacuum cleaner brush does not rotate: Possible causes and troubleshooting tips
Let’s look at some of the likely issues with your shark brush roller not rotating and how to fix them.
This advice is for many of the Shark vacuum cleaners, including Shark Rotator, DuoClean, Shark Apex or Navigator Lift away. But it is still a good idea to check the manufacturer’s instructions for your specific model.
Cause 1: The brush roller is not turned on
Your Shark vacuum cleaner has a switch to activate the rotating brush roller. So first, make sure that it is turned on in the correct position.
The position of the scroll brush button depends on your shark cleaner. Some Shark models are labeled “I” or “II,” while others use “Carpet” or “Hard Floor” options.
To make the Shark vacuum brush spin, make sure the switch is set to “II” or “Carpet”. This starts the brush roller spinning, ready for you to clean carpets and rugs. The “I” and “Hard Floor” settings use just suction alone, which is better for cleaning bare floors.
- Check the brush roller switch and make sure it is on “II” or “Carpet”.
- If not, just slide the selector to the correct setting. The shark vacuum cleaner brush turns on automatically when you lean the vacuum lever back.
It is best to check that this is not the cause of the problem before looking at other options.
Cause 2: The vacuum cleaner is locked in the wrong position
If your Shark vacuum cleaner is in an upright position, the brush roller may not rotate. The brush roller indicator light is still green, but it will not rotate.
Fortunately, this is easy to fix by changing the position of your shark vacuum cleaner.
Simply lean back the vacuum housing to unlock it. The brush roller should start rotating automatically.
Cause 3: You used the wrong setting
Your Shark vacuum cleaner will have different suction power settings to suit different floor types.
If you do not get the setup right, the brush motor may stall. This turns the indicator light red and the brush roller stops rotating. This happens on rugs with high pile or thick rugs.
So when cleaning these surfaces, check if your shark vacuum cleaner has a thick carpet condition. If so, set it to this. Otherwise, you can turn down the suction power to the lowest setting and see if this solves the problem.
- When cleaning long-pile carpets, turn the suction control down to the minimum setting. Some Shark vacuum models will have a “thick blanket” setting so you can use this instead.
- Once you have selected the correct mode for the job, turn on the power.
- Put the handle back to activate your Shark roller brush.
Cause 4: There is a blockage in your shark vacuum cleaner brush or hose
If there is a blockage in the brush bar or hose, your shark vacuum cleaner can automatically shut off to prevent any damage.
And if it does not close by itself, you may find that the brush does not spin. Otherwise, it may cause a broken belt in your vacuum cleaner. And that’s something you want to avoid!
If this happens, you will notice a red light on the indicator that warns you that something is not right. You must use the power switch to turn off your shark vacuum cleaner and unblock it immediately.
- Turn off and unplug your shark vacuum cleaner.
- Check the hose and brush roller for any blockages, such as tangled hair or lumps of large dirt. Remove everything you find.
- It is a good idea to clean the Shark vacuum cleaner brush and hose to minimize the risk of a broken belt. Remove the roller brush for a more thorough cleaning or to cut hair and fibers off it.
- And you can clean the hose with cold water and a wire hanger to remove lumps.
- Wait 24 hours for all washable parts to dry, then reconnect the pieces before turning on the vacuum cleaner again.
Cause 5: There is damage to the belt
In the worst case, the belt may have broken to where it needs to be replaced.
The conveyor belt keeps the brush roller running in your shark vacuum cleaner. So if it is damaged or worn, it makes sense that it may be the reason the brush bar is not rotating.
If your vacuum sounds different from usual, it is a sign that the belt is worn down. It’s a good idea to check it regularly so you do not get caught when the brush roller suddenly stops spinning.
But if this happens, a replacement belt should solve the problem.
- Replace the conveyor belt in your shark vacuum cleaner.
- To do this, remove the brush roller plate, push off the old belt and replace it with a new one.
- Gather everything again and you are well on your way.
- But be sure to turn off your vacuum cleaner and disconnect it from the mains before performing maintenance.
Cause 6: There is a connection issue
A revealing sign of a connection problem on your shark vacuum cleaner is flashing LED headlights or no indicator light at all.
If a red or green light does not appear, you may have a connection problem between the different parts of your shark vacuum cleaner. Check that the major unit, the rod and the nozzle head are all properly connected.
If the LEDs are flashing, the brush compartment may not be closed properly. So check if it is still open. If not closed tightly, the Shark vacuum brush roller will not rotate for safety reasons.
For both scenarios, check your shark vacuum cleaner to make sure everything is properly attached. This includes all the separate components as well as ensuring that the roller brush compartment is closed.
Cause 7: A full dust cup or clogged lint screen
When the dust cup reaches its maximum level, the brush roller stops rotating to prevent your Shark vacuum cleaner from becoming overfilled.
The same goes for the lint screen. If it becomes clogged, the brush does not rotate to protect the motor. This simply means that your vacuum cleaner is too full and needs some basic maintenance to get it running again.
The dust container and lint screen are easy to access to clear them out.
- Remove the dust cup from your Shark vacuum cleaner and use the release button to empty it in your trash.
- Gently brush the lint screen to remove dirt from it.
- Replace both before using your vacuum cleaner.
Remember to turn off and unplug any shark vacuum cleaners before performing any maintenance.
Cause 8: The engine is overheated
Shark vacuum cleaners use a motor-protective thermostat, so it switches off if the motor overheats.
If the roller brush gets stuck, let’s say there is a tangled hair buildup or blockage, then it is highly likely that it is causing problems with overheating. And this is where the engine stops to prevent serious damage.
If this happens, the indicator light will flash red and your shark vacuum cleaner will turn itself off.
There are a few steps you need to follow in this case:
- Turn off the vacuum cleaner and unplug it
- Empty the dust cup as usual
- While the dust cup is still off, clean the felt and foam filter with water.
- If your Shark uses a HEPA filter, remove the floor nozzle to access it for cleaning
- Examine the vacuum roller brush for any blockages. Remove any animal hair or carpet fibers you find inside. A clean roller brush helps prevent overheating.
- Allow your Shark vacuum to cool for at least 45 minutes
- Replace all components and hose connection before turning on your shark vacuum cleaner again
