Understanding Vacuum Cleaner Noise

Vacuum cleaner noise primarily stems from three key sources: the motor, airflow, and mechanical components.

Motor Noise: The heart of any vacuum cleaner is the motor. It is responsible for generating the majority of the noise. It operates by creating suction and driving the airflow necessary for cleaning. This mechanical process produces vibrations and sound. A higher-powered motor often results in a louder vacuum.

Airflow Noise: As air rushes through the vacuum cleaners’ hoses, filters, and dust collection system, it can create a whooshing or whistling noise. These components’ design and the airflow speed significantly affect the noise level.

Mechanical Noise: Mechanical parts, such as the brush roll, can contribute to noise as they rotate and contact surfaces. The type of flooring you’re cleaning, whether carpet, hardwood, or tile, can also impact this noise level.

How Loud is A Vacuum Cleaner?

The noise produced by a vacuum cleaner is typically measured in decibels (dB). A standard vacuum has noise levels ranging from 70 dB to 85 dB.

Some high-powered models can even exceed 85 dB. In perspective, a normal conversation occurs at around 60 dB, while prolonged exposure to noise levels above 85 dB can be harmful.

1. Clean Dirty Filters

Noisy vacuum cleaners are often the result of neglecting those trusty filters. Dirty filters can lead to increased noise and reduced efficiency.

To address this issue, turn off your vacuum cleaner and unplug it. Then, carefully remove the filters. Ensure that you follow the manufacturer’s instructions for your specific vacuum model. Gently tap the filters to dislodge loose dirt, or for more stubborn debris, use a soft brush or wash them, allowing them to dry thoroughly before reinserting them. This simple step can work wonders in reducing the noise your vacuum produces.

2. Remove any clogs

Clogs are notorious for increasing noise levels while decreasing your vacuum’s suction power. To resolve this issue, check the vacuum hose, especially where it bends or has attachments.

Use a flashlight to inspect the hose’s interior, and if you spot any blockage, use a long, flexible tool or a wire hanger to dislodge the clog gently.

Also, inspect the vacuum’s brush and nozzle for debris obstructing airflow. Removing clogs is vital to achieving a quieter, more efficient vacuum cleaner.

3. Cover the Air Outlet

 Reducing noise in your vacuum cleaner can be as simple as covering the air outlet. This strategy can effectively muffle the sound produced by your vacuum. You have a few options for this.

One approach is using soundproofing material, such as foam or rubber, to wrap around the air outlet. Ensure that the covering does not obstruct the airflow significantly, as that can affect the vacuum’s performance.

Alternatively, you can create a makeshift silencer using a box or a container designed to fit around the air outlet. The key here is to experiment with different materials and designs to find what works best for your specific vacuum model.

Covering the air outlet can be a game-changer in your quest for a quieter vacuuming experience.

4. Inspect broken brush bearings

Damaged brush bearings can contribute to that unpleasant noise your vacuum produces. Inspecting and maintaining the brush bearings is crucial to keep noise levels at bay. Start by unplugging your vacuum and flipping it over to access the brush.

Carefully remove it, following the manufacturer’s guidelines. Examine the bearings for any visible damage or wear. If you notice any issues, replace the damaged parts with suitable replacements.

Regular inspection and maintenance of your brush bearings will reduce noise and extend the life of your vacuum cleaner.

5. Fix/replace a broken fan

The fan in your vacuum plays a vital role in creating suction but can also be a noise source when damaged. A broken fan can lead to increased noise levels.

Start by turning off and unplugging your vacuum, then gain access to the fan assembly according to your vacuum’s user manual. Inspect the fan for any visible cracks, chips, or damage. If you discover any issues, consider replacing the fan with a suitable replacement part.

Fixing or replacing the fan can significantly reduce the noise generated by your vacuum, making your cleaning routine more pleasant.

6. Clean Dusty Motor

A dusty motor can contribute to the noise issue, and addressing this concern is essential for a quieter vacuum cleaner. Dust accumulation can hinder your motor’s performance and make it noisier.

Begin by unplugging the vacuum cleaner and removing the motor cover per your user manual’s instructions. Use a soft brush or compressed air to gently clean away the accumulated dust and debris.

Be thorough, but handle the motor components with care. Once cleaned, reassemble the motor and motor cover, and your vacuum should operate with reduced noise levels.

7. Replace the motor with a Quieter One

 If your vacuum cleaner’s motor is beyond cleaning or repair, consider replacing it with a quieter model. The choice of motor can significantly impact your vacuum’s noise levels. Look for motors designed for reduced noise emissions.

Compare different models and brands to find one that suits your vacuum cleaner and provides a quieter cleaning experience. Make sure to follow the manufacturer’s guidelines when replacing the motor to ensure a safe and effective transition.

8. Build a Vacuum Cleaner Muffler Box

Building a muffler box is one of the most effective ways to achieve a quieter vacuum cleaner. This ingenious device can significantly reduce noise levels during operation.

You’ll need materials like plywood, foam, and acoustic materials to create your muffler box. Follow a step-by-step guide to design and construct the box that fits around your vacuum.

Ensure it has enough space for airflow to prevent overheating. A muffler box can make your vacuum cleaning sessions more peaceful and enjoyable when used correctly.

9. Purchase a Quiet Vacuum Cleaner

If you’re in the market for a new vacuum cleaner, select one specifically designed for quiet operation. The motor and design of a vacuum significantly impact its noise levels. Look for models explicitly labeled as “quiet” or “low noise.” Many manufacturers now produce vacuum cleaners with advanced sound insulation and quieter motors. Research and compare different models and read reviews to find a vacuum that suits your needs and ensures a quieter cleaning experience. This is an excellent long-term solution for noise reduction.


In this comprehensive guide, we’ve explored various strategies to make your vacuum cleaner quieter. From cleaning filters and removing clogs to inspecting and maintaining essential components, we’ve provided practical steps to achieve a quieter cleaning experience. We’ve also discussed the benefits of covering the air outlet and the option of replacing a noisy motor with a quieter one. For those seeking a more advanced solution, we’ve delved into building a vacuum cleaner muffler box, a highly effective method for noise reduction. Additionally, we’ve highlighted the advantages of purchasing a quiet vacuum cleaner designed for low-noise operation.

Implementing these strategies can transform your noisy vacuum cleaner into a quiet and efficient cleaning companion.
