Is your Shark vacuum suddenly acting up with weird suction noises? Well, I can relate. I once had a Roomba that started making an obnoxiously loud racket, which prompted me to seek a quieter solution – a shop vac. Now, don’t get me wrong, shop vacs are undeniably powerful and get the job done effortlessly, but they come with their fair share of drawbacks. They tend to be expensive, bulky, and not ideal for those of us living in compact apartments where every inch of space counts.

The appeal of a shop vac is understandable – they’re workhorses, tackling dirt and messes with ease. However, I also understand that not everyone has the budget to invest in an alternative vacuum cleaner that promises lightning-fast cleaning at the cost of an arm and a leg. So, if you’re determined to fix your Shark vacuum cleaner, weird suction noises and all, without emptying your wallet, you’re in the right place.

I’ve crafted this guide to help you troubleshoot and resolve all those bizarre noises your Shark vacuum cleaner might be making. Because let’s face it, we all want our cleaning appliances to work seamlessly, quietly, and without causing any financial headaches. Let’s get to the bottom of those noises and have your Shark vacuum running smoothly once more.

Shark Vacuum Making Weird Suction Noise

Why is Shark Vacuum Making Weird Suction Noise?

Your shark vacuum will produce all sorts of noises, from grinding noises, rattling to whistling noises. Each of these sounds indicates a different problem that must be addressed or else could result in damage to your vacuum cleaner.

For example, a rattling noise is an indicator that your vacuum cleaner has sucked something like a pebble, socks, or something hard.

Whistling noises is an indicator that there could be holes or tears in your vacuum cleaner, causing air leaks.  Grinding noise indicates that one of the moving parts of the vacuum cleaner is jammed, and the jammed part needs to be fixed.

In general, if your Shark vacuum is making noise, it could be due to several reasons. Here are some common issues and their potential solutions:

  1. Clogs or Blockages: Check the vacuum’s hose, brush roll, and any other attachments for clogs or blockages. Even a small obstruction can cause unusual noises. Remove any debris you find, and make sure the airflow is unobstructed.
  2. Dirty Filters: Dirty or clogged filters can restrict airflow and make the vacuum work harder, leading to strange noises. Check and clean or replace the filters as per the manufacturer’s instructions.
  3. Worn or Damaged Parts: Over time, various components of the vacuum, such as the brush roll, belts, or seals, can wear out or become damaged. Inspect these parts for signs of wear and tear and replace them if necessary.
  4. Foreign Objects: Sometimes, small objects like coins, toys, or hairpins can get lodged in the vacuum’s internal components, causing unusual noises. Turn off the vacuum, unplug it, and carefully inspect the internal components for foreign objects.
  5. Loose or Misaligned Parts: Loose or misaligned parts within the vacuum, such as the brush roll or hoses, can create strange noises when the vacuum is in use. Ensure that all components are properly secured and aligned.
  6. Belt Issues: If your Shark vacuum has a brush roll with a belt drive, a worn or damaged belt can produce unusual noises. Check the condition of the belt and replace it if necessary. Consult your vacuum’s manual for guidance on how to access and replace the belt.
  7. Motor Problems: Unusual noises can also stem from motor issues. If you suspect a problem with the motor, it’s best to contact Shark customer support or a professional technician for diagnosis and repair.
  8. Excessive Debris: If the vacuum is picking up large amounts of debris, it may create more noise than usual. Empty the dustbin or canister regularly to maintain efficient operation.
  9. Improper Use: Ensure that you are using the vacuum correctly according to the manufacturer’s guidelines. Using it on surfaces it’s not designed for or forcing it to pick up large items can strain the motor and create odd noises.
  10. Lubrication: Some vacuum models have moving parts that require periodic lubrication. Refer to your vacuum’s manual for maintenance instructions, including any lubrication requirements.
  11. Maintenance: Regular maintenance, such as cleaning the brush roll, emptying the dustbin, and checking for loose parts, can prevent many issues that lead to strange suction noises.

Shark Vacuum Making Loud Air Noise

In order to properly troubleshoot the reason why your shark vacuum is making loud air noise, it’s important to understand the different types of noise a vacuum cleaner makes and how you can troubleshoot them.

The different types of noises a shark vacuum makes are:

  • Shark Vacuum Loud grinding noises
  • Vacuum Rattling noises
  • Shark Vacuum Whistling noises
  • Vacuum High pitched noises

Shark Vacuum Loud Grinding Noises

All shark vacuums on the market today have moving parts. If you own one and hear loud grinding noises coming from the unit, then it’s likely that one of the moving parts is jammed or multiple of them are jammed.

Examples of the moving parts include the moving brushes and rotating brush roll found in Shark Robot Vacuum cleaners.

These moving parts get jammed, especially when something that’s too large for the vacuum to suck in is trapped in the suction area. A good example is when the brush rolls get entangled with a piece of small cloth like a sock or small debris on the floor.

Despite the obstruction, the moving parts will struggle to continue moving. This will, in turn, produce a grinding sound that will only end when the blocking dirt is removed or when the motor burns out.

To fix this problem, you’ll need to inspect the cause of the jam and remove it.

  • You will need to figure out the source of the grinding noise.
  • Switch off the vacuum and inspect the particular part where the noise is coming from.
  • Remember to gently remove the blocking dirt, or otherwise, you risk damaging the components of your shark vacuum cleaner.

Shark Vacuum Rattling Noises

If you hear a rattling noise coming from your vacuum, it’s likely because the vacuum has inadvertently sucked up a hard object into its bin. Vacuums have the capability to ingest items that are small and light enough to pass through their air pathways. Unfortunately, this category includes hard objects like pebbles, rocks, marbles, paperclips, and more.

When these rigid items enter the vacuum’s bin, they tend to bounce around inside, colliding with the bin’s walls, thereby generating the rattling noise you’re hearing. To resolve this issue, you can follow these steps:

  • Empty the vacuum’s bin and inspect it to ensure that no hard items are trapped inside.
  • Examine the hose or wand as well, as some of these objects might have become lodged in other parts of the vacuum. Removing them will prevent the rattling noise from recurring in the future.

In the case of Shark vacuum models equipped with powerheads, a small drive motor is responsible for turning the brush roll. This is achieved through the rotation of a rubber belt, which transmits energy to the brush roll, causing it to spin continuously. Here’s why you might experience a rattling noise in the powerhead:

Over time, this rubber belt undergoes normal wear and tear, which can lead it to crack and eventually snap. Even after breaking, the motor continues attempting to turn the damaged belt, resulting in a noise that resembles rattling emanating from the powerhead. A clear indicator of a broken belt is a rattling noise accompanied by the failure of the brush bar to spin as it should.

To address this issue, you can follow these steps:

  • Remove the powerhead from the rest of the vacuum and place it on a suitable work surface.
  • Take off the soleplate to access the internal components of the powerhead.
  • Inside, you’ll find the rubber belt or any remnants of it. Ensure that you remove the damaged belt and any broken pieces you encounter.
  • Next, place the new belt around the motor and the brush bar. Verify that the belt is correctly aligned by manually turning the brush bar.
  • Finally, reattach the soleplate by securing any screws that were previously removed.

By replacing the broken or snapped belt, you should be able to eliminate the rattling noise and restore proper functioning to your Shark vacuum’s powerhead.

Shark Vacuum Whistling Noises

Whistling or something that sounds like a whooshing sound from your shark vacuum cleaner is an indicator of a problem with the vacuum’s body. The most common cause of the whistling sound is an air leak. When the vacuum cleaner is in perfect working condition, all the air will be sucked in through the hose or wand into the collection bin.

In simple terms, whistling noises indicate that the vacuum cleaner is sucking air from somewhere else than the vac’s wand or hose. It means that there is a tear or hole in the flexible hose or the wand.

Air leaks can also happen when the joints in the wand or the flexible hose aren’t closed tightly. This results in a poor tight seal that allows air to be sucked in.

To fix the whistling noise, you will need to identify the source of the air leak.

  • If the air leak comes from a hole in the wand or hole, you will need a replacement. This is because these parts cannot be repaired.
  • You can temporarily seal the air leak using duct tape.
  • However, if the air leak comes from the vac’s cover, you should inspect whether there’s something preventing it from closing entirely. It could be that some dirt is trapped in the cover seal.

Shark Vacuum High Pitched Noises

Did your shark vacuum immediately produce high-pitched noise? If that’s the case, then it could be as a result of blockage or that the filters could be clogged or damaged.

Blockage is quite common in all vacuum cleaners. It happens as dirt builds up such that it won’t allow any air to flow smoothly through the filter. Another possible reason for the blockage could be that the vacuum cleaner has sucked something that has clogged the airways- something like a piece of cloth, lint or socks.

Despite the blockage, the suction motor will continue spinning, and as a result, the motor becomes so loud and produce high-pitched noise.

To fix this problem, you will need to inspect the vacuum and remove any blockages.

  • Disconnect the vacuum wand, hose and all other attachments. Inspect each piece; use a flashlight to inspect the wand and the hose.
  • It can be challenging to inspect the flexible hose using a flashlight. Instead, drop a coin on one end and see if it falls out on the other end. If it doesn’t, then the hose is blocked and needs your attention.

Dirty or damaged filters can also cause high-pitched noises. It’s important to note that air must be able to pass through the filter without much resistance. When the filter gets saturated with dust or dirt, your vacuum will struggle to move the air through the filter hence high-pitched noises.

To fix this problem, you will have to:

  • Clean washable filters thoroughly with warm water to get rid of the dirt.
  • For non-washable filters, manually remove the dirt or blow high-pressure air through them to get rid of hard to remove dust and dirt stuck on them.
  • If the filters are worn out, you will need to replace them.
