Why Does Shark Stick Vacuum Make Noise?

A vacuum cleaner is designed to make some sound, but loud grinding, rattling, whistling, or screeching noises are not normal.

Here are the most common reasons your Shark stick vacuum may be making noise.

Clogged Air Path

When dirt, dust, hair, or debris blocks the airflow, the motor has to work harder. This extra strain often causes a loud or high-pitched noise. Blockages can happen in the wand, hose, floor head, or dust cup.

Hair Tangled Around the Brush Roll

Hair and string easily wrap around the brush roll, especially if you vacuum carpets or pet hair. When the brush roll cannot spin freely, it creates a loud rattling or grinding sound.

Dirty or Clogged Filters

Shark vacuums use filters to trap fine dust. Over time, these filters get clogged. When air cannot pass through properly, the vacuum may whistle or sound louder than usual.

Loose Parts

If a component like the dust cup, wand, or floor nozzle is not attached properly, it can vibrate and create noise during operation.

Worn Brush Roll or Belt

With long term use, the brush roll or belt can wear out. This can cause squeaking, clicking, or grinding sounds.

Motor Issues

In rare cases, internal motor problems can cause loud noises. This is usually accompanied by burning smells or overheating. Most beginners will not face this issue, but it is worth mentioning.

Shark Stick Vacuum Making Noise [Easy Fixes]

Now, let us go through the fixes step by step. Start with Step 1 and move forward. In most cases, the problem will be solved before you reach the last step.

Step 1: Turn Off and Unplug the Vacuum

Safety always comes first.

Before touching any part of the vacuum, turn it off and unplug it from the power source. If your Shark stick vacuum is cordless, remove the battery if possible.

This prevents accidental starts and protects you from injury.

Step 2: Check the Floor Nozzle for Debris

Flip the vacuum upside down so you can see the bottom of the floor head.

Look for:

Large debris is stuck near the brush roll
Coins, paper clips, or small toys
Carpet fibers wrapped around moving parts

Remove anything you see using your fingers or a pair of tweezers.

Even small objects can cause loud rattling noises.

Step 3: Clean the Brush Roll Thoroughly

Hair buildup is one of the most common reasons for noise.

Steps to clean the brush roll:

Locate the brush roll cover. On most Shark models, this is held by clips or screws.
Open the cover carefully.
Pull out the brush roll.
Use scissors to cut away hair and threads.
Remove all debris from both ends of the brush roll.
Reinsert the brush roll and close the cover securely.

Make sure the brush roll spins freely before turning the vacuum back on.

Step 4: Inspect the Wand and Hose for Blockages

Disconnect the wand and hose from the vacuum body.

Hold each piece up to the light and look through it. If you cannot see light clearly, there may be a clog.

To clear blockages:

Use a broom handle to gently push debris out
Shake the wand to loosen dirt
Rinse with water if allowed by the manufacturer, and let it dry completely

Never use the vacuum until all parts are fully dry.

Step 5: Empty and Clean the Dust Cup

A full dust cup restricts airflow and increases noise.

Steps:

Remove the dust cup from the vacuum.
Empty it into a trash bin.
Tap the sides gently to release stuck dust.
Wipe the inside with a dry or slightly damp cloth.

Make sure the dust cup is completely dry before reinstalling it.

Step 6: Clean the Filters

Dirty filters are a major cause of loud vacuum noises.

Most Shark stick vacuums have:

One foam filter
One felt or HEPA filter

Steps to clean filters:

Remove the filters according to your model instructions.
Rinse them under cold water.
Do not use soap unless the manual allows it.
Squeeze out excess water gently.
Let the filters air dry for at least 24 hours.

Never reinstall wet filters, as this can damage the motor.

Step 7: Check for Loose or Misaligned Parts

Reassemble the vacuum carefully.

Make sure:

The dust cup clicks into place
The wand is fully inserted
The floor nozzle is attached securely

Loose connections can cause vibrating or rattling noises during use.

Step 8: Inspect the Belt and Brush Roll Ends

If your model uses a belt, check it for:

Cracks
Slack
Signs of wear

A worn belt can slip and make squealing noises. If the belt looks damaged, it should be replaced.

Also, check the ends of the brush roll for debris that may affect rotation.

Step 9: Test the Vacuum on a Hard Floor

After cleaning and reassembling everything, test the vacuum on a hard floor first.

Listen carefully:

The sound should be smooth and consistent
No grinding or rattling should be present

If the noise is gone, the issue has been fixed.

Step 10: Contact Shark Support if Noise Persists

If you have tried all the steps above and the vacuum still makes a loud noise, it may be a motor issue.

In this case:

Stop using the vacuum
Check if it is under warranty
Contact Shark customer support for professional help

FAQs

Is it normal for a Shark stick vacuum to make noise?

Yes, some noise is normal. Vacuums use powerful motors and airflow. However, loud grinding, screeching, or rattling sounds are not normal and usually indicate a problem.

Can clogged filters make the vacuum louder?

Yes, clogged filters restrict airflow and force the motor to work harder. This often results in louder operation and sometimes a whistling sound.

How often should I clean my Shark vacuum filters?

For best performance, clean the filters once every month. If you have pets or vacuum frequently, clean them more often.

Why does my vacuum make noise only on carpet?

Carpet fibers and hair can wrap around the brush roll more easily. This increases resistance and noise. Cleaning the brush roll usually fixes this issue.

Can I continue using my vacuum if it is noisy?

It is not recommended. Continued use may damage the motor or internal parts. Always identify and fix the cause of the noise first.

Does washing filters damage the vacuum?

No, as long as you follow the manufacturer’s instructions and allow the filters to dry completely before reinstalling them.
