This is a pretty common cause of the weird noises your Shark vacuum cleaner may emit. Vacuum cleaners are pretty sensitive about what they swallow. They are open to sucking in dust, sand, and small debris, but when it’s a sock, clumps of hair, folded pieces of paper, or coins, then there’s a problem.

It is important to inspect the surface you intend to vacuum before you begin. Apart from causing your Shark vacuum cleaner to make weird suction noises, clogs may lead to blockages that may need technical help to fix.

Dirty filters

There is a chance that if your Shark vacuum has suddenly begun to emit those annoying noises, dirty filters may be the problem.

Vacuum filters serve a very important purpose. Primary filters collect a good proportion of the dust, hair, dirt, and other tiny debris that have been suctioned into the vacuum cleaner before they can be pushed out back into the environment. Secondary filters on the other hand, further purify the air that has passed through the primary filter. It collects all finer particles that have made it past the primary filters.

Over time, filters gather up so much dirt. This affects the vacuum cleaner as it has to work harder to create enough suction to properly clean your surfaces. As a result, your Shark vacuum will begin to make those weird and annoying suction noises.

Broken Fan

Conversely, the weird suction noises your Shark vacuum cleaner makes may be a result of a broken fan. The fan plays an essential role in your vacuum cleaner, preventing it from overheating.

After a while, lots of dirt will run through your Shark vacuum cleaner’s motor and collect on the fan. Eventually, it will cause the fan to break. When this happens, the vacuum cleaner begins to emit a louder noise, with the sound from the broken fan combining with the suction sound of your vacuum cleaner.

If your Shark vacuum cleaner has a broken fan, you should take it to a repairer.

  • If the clog is in the head, you may be able to pull it out with your fingers, a toothbrush, or a pen.
  • If it is in the hose, gently poke through the hose with a mop stick or a straightened wire hanger, until the clog drops out.
  • Test the vacuum to see if the noise is gone.
