Possible Causes and Troubleshooting Ideas of Vacuum’s Roller Brush not Spinning

The cleaning industry experts have tested different models of the Shark Vacuums and came to the conclusion that a common issue is that the roller brushes are not spinning.

Following causes and possible solutions to this problem could stop you from worrying in this scenario:

The Belt is Broken / not Working properly

The belts inside the machine cause the roller brush to spin. If it is untied to the mechanics, there is no way that roller brush starts, and eventually it will be in not moving position.

All you need to do is to replace the broken belt with a new belt. The belts are easily available in market at reasonable prices.

Displaced or Loose Nozzle- A major reason why Vacuum Roller isn’t Moving

If the nozzle is disengaged or in a loose position, it is probably the solid reason the brush roller is unable to spin.

If this is the case, make sure to press the handle firmly to attach the nozzle, and see if the vacuum cleaner now starts or not.

Blocked Brush Roll or Other Parts

Shark Vacuums have a safe protective mode, in which if some spare part stop working, a vacuum will stop and shut down in nanoseconds.

So, if the vacuum shuts down while doing cleaning, the blockage has happened for sure.

To solve this, you should clean the dustbin to make sure that there is no clogging.

Another thing to do is to check for a blocked hose, if it is blocked, you may unclog it.

Occasionally, hair from the surfaces blocks the roller. For this, brush bristles must be cleaned from hair on the roller.

The Roller Brush Switch is OFF

Sometimes, it is the possibility that the switch of the roller brush is off.

Some models of shark vacuums come with LED light indicators which show if the brush is working or not.

Green light means the brush is working and a red light indicates the brush is in the stop position. Turn on the roller, if it is off. 

The Dust Box is Full

There is the possibility that the brush roller of the vacuum starts and then stops just because the dust box is full.

You must always empty and clean the dust box before using it for second time. 

Experts have conducted experiment with empty and full dust boxes to see how much dirt the vacuum cleaner could pick.

The results showed that empty dust boxes cleaner always perform well in cleaning. 

It is recommended to empty the dust box before it could reach the fill line because more dust in the box will bring less suction.
