This will give you a better idea of what to do if this is the issue with your Shark.

The Roller Brushes are Tangled:

To identify the cause of a strange, rattling noise, check the roller or beater brushes. If your Shark Navigator Lift-Away is making a strange clicking noise, it may be an issue with the brush rolls.

Many vacuums allow you to turn off these brushes, solving the issue temporarily. For a more lasting solution, you can remove the brushes from the vacuum and remove whatever is stuck in them.

The Roller Brush Belt Has Slipped Off:

In many vacuum cleaners, especially canisters, you might have faced the problem of the belt popping off, creating rustling, crackling noises. If this is the case, slipping it back on or replacing the belt will solve the problem.

Bear in mind that this may happen only if you’ve been using your vacuum for a while. If you recently brought your Shark vacuum, this is most likely not the case.

The Filter Has Broken:

Strange noises from your vacuum can also be an indication that your filter has broken or is extremely clogged and dirty. Check the filter, and if it is broken or filthy, replace it with a new one. This will also allow your vacuum to better clean your house.

The Fan is Damaged:

Strange suction noises from your Shark vacuum cleaner can be the result of a broken fan. The fan plays a vital role in your vacuum cleaner, preventing the unit from overheating. After frequent use, dirt will pass through your Shark vacuum cleaner’s motor and accumulate on the fan. 

This can sometimes cause the fan to break, causing the vacuum cleaner to create a louder noise. If this happens, it’s best to take it to get professionally repaired.

The Motor is Damaged:
