Why Is My Shark Vacuum Making Weird Suction Noise?

The ideal role of technology is to make our lives fundamentally easier and not have to worry about the mundane. Unfortunately, however, it can also be the cause of your headache from time to time.

Cleaning is one of those tedious and routine tasks that we often rely on the help of technology for. And Shark vacuums are the go-to vacuum cleaners when it comes to getting the job done with maximum efficiency.

Nevertheless, Shark vacuums are no exceptions to having an issue or two every once in a while. If your Shark vacuum is making weird suction noises, then you’ve come to the right place.

Our troubleshooting guide here will help you identify the issue with your Shark vacuum as well as outline what you have to do to fix it.

Why is my Shark vacuum making weird suction noise?

The reason your Shark vacuum is making weird suction noises could be due to a variety of factors. The most common causes include blockages, dirty or damaged filters, or an air leak. It could also be a direct result of a broken fan or a damaged brush roll. Inspecting it closely is the first step.

Vacuum cleaners aren’t exactly silent when they are turned on. However, it’s possible for your vacuum to become obnoxiously loud if you don’t maintain it properly. This could be due to a number of reasons.

When it comes to Shark vacuums, the primary cause for them making unusual sounds is likely due to dirt or dust blocking the airflow. Let’s take a closer look at some of these reasons to give you a better idea of what to look for.

Dirty and Damaged Filters:

This is one of the most common issues to run into that can alter the sound of your Shark vacuum. Filters are bound to get dirty the more you use your vacuum, and they are prone to damage if you don’t clean them routinely.

Vacuum filters are responsible for filtering out the dust and dirt that gets sucked in through the hose. Shark vacuums usually have two of them. A primary one that filters a good portion of the dust, tiny debris, dirt, and hair which is then stored in the canister.

The secondary filter on the other hand filters the tiny particles that were able to pass through the primary one to purify the suctioned air further. Repeated use of the vacuum causes dirt and debris to accumulate on these filters over time and this affects the flow of air in your vacuum. The weird suction noises are a direct result of such.


If your Shark vacuum has no suction and making loud noise, it could be due to a blockage or a clogged-up hose. In household settings, it’s usually pieces of clothing or clumps of hair or paper that block the airflow and cause the suction to stop.

On the other hand, if your Shark vacuum is making weird noise from the side, check the canisters for any solid objects that might be stuck.

Air Leak:

Continued use of the vacuum can often lead to holes and tears in the hose and canister. If the noise coming from your Shark vacuum sounds like a high-pitched whistle, then you should check it for any leaks that might be compromising the suction.

Faulty or Broken Fan:

Most Shark vacuum cleaners have a fan that plays an essential role in preventing them from overheating. When the vacuum motor sucks in dust through the hose, it can lead to the fan being jammed.

If your shark vacuum is making loud noise and burnt smell, it’s because the fan isn’t working properly.

Dirty or Damaged Brush Roll:

Last but not least, a dirty brush roll is another reason that can cause your Shark vacuum to make weird noises.

If a piece of debris gets stuck in the brush, it can lead to the vacuum making loud noises. A damaged brush roll could also cause be a potential culprit.
