When operating vacuum cleaners, we can constantly hear noises. When switched on, even the supposedly silent vacuum cleaner can be heard plainly. Vacuum cleaner noise is measured in decibels, which can be a very complicated unit. What do these vacuum-related decibel levels mean? I’ll explain what the vacuum’s noise level means and how to make it into a recognizable condition in this essay.
How Many Decibels Does a Vacuum Cleaner Have?
Before we talk about decibels in vacuum cleaners, let’s explain how decibels work and to what extent they are too loud. Decibel is used to measure the intensity of the sound emitted when starting up. Some sounds are very low and comfortable, while others are too loud and you need to wear ear protectors.
The occupational safety and health administration recommends wearing hearing protection devices of 85 dB and above. Because over time, this noise level may damage your hearing, so 70 dB for a vacuum cleaner or less is acceptable. Some examples of common sounds can help you understand different noise levels:
- Normal conversation between two persons: 60 dB
- Refrigerator: 50 dB
- Washing machine: 50-75 DB
- TV: 70 dB
- Doorbell: 70-80 DB
- Mower: 60-95 DB
- Garbage disposal: 80 dB
- Vacuum cleaner: 56-80 DB
As you can see, vacuum cleaners usually work at 56-80 DB noise levels. The noise level of the full-size vacuum cleaner is 70-80 dB, which is very large, the same as garbage disposal. These high decibels are uncomfortable for your ears and will cause great pressure on anyone near the vacuum cleaner. If the phone rings, you won’t hear anything around you. These days, many people are looking for quiet vacuum cleaners. Although vacuum cleaners will never be completely quiet, many vacuum cleaners on the market today are considered extremely quiet. The noise level of these vacuum cleaners is 65 dB or less.
Example of silent vacuum cleaner:
- Miele complete C3 canister vacuum cleaner -56 – 67 DB
- Eufy Robo VAC 11S – quiet operation mode -56 DB
- Moosoo K17 cordless bar -65 DB
- Ecovac deebot ozmo 950 robot – 53 DB
- Coredy robot vacuum cleaner -45 – 65 dB
- Hoover commercial silent vacuum cleaner – up to 62 dB in silent mode
- Electrolux El 4021A silent performer -65 DB
- Nacecare Henry HVR 200 canister – 47 DB
- Miele compact C1 pure suction tank – 50 dB
- iRobot Roomba–60 dB
So, if you want to buy a new vacuum cleaner, where should you find the decibel of a vacuum cleaner. Maybe you are interested in knowing the noise level of your current cleaner.
What is the Ideal Decibel Level of Vacuum Cleaner?
The noise of most full-size vacuum cleaners is 70 to 80 dB. For example, 80 dB is the noise level generated by a typical waste treatment system. The sound level of 70 dB is significantly lower than 80 dB. Vacuum cleaners with a decibel of 80dB should not be classified as “ultra silent” or “silent”. Each vacuum cleaner has different functions. “Formal” I consider a vacuum cleaner that produces a maximum DB level of 67 dB. Although manufacturers have recently developed vacuum cleaners.
What is the Decibel of a Silent Vacuum?
The vacuum cleaner makes noise. Even the most silent vacuum cleaner can hear sound when in use. If you often use a vacuum cleaner when your child is sleeping or on Sunday morning, we suggest you use a silent vacuum cleaner. The maximum noise level of the silent vacuum cleaner is 60dB. In addition, these are bag vacuum cleaners, because bags can reduce noise.
Noise Level of Popular Vacuum Cleaners
Because the popular Dyson vacuum cleaner (DC12) sounds too noisy, UNICEF Japan uses a conventional noise meter to measure the actual loudness. The sound meter measures sound in decibels (DB). We compared Dyson with three other vacuum cleaners on the market.
Dyson has two modes, “weak” or “strong”. We found that compared with other vacuum cleaners, the loudness of “strong” mode is indeed very strong. As shown in the figure, the “strong” mode sound of Dyson model is the largest, reaching more than 90 dB. When we compare the “weak” mode, Toshiba model is the most noisy of all models. In the “weak” mode, the noise remains at about 80 dB, and in the “strong” mode, the noise is slightly lower than 85 dB. Dyson’s “strong” mode noise is also considered by some people to be quite unpleasant.
The noise level depends on how the machine engine is designed. Usually, a fan rotates at a very high speed, and the centrifugal force exhausts the air, so the air is sucked in at the center and blown out at the periphery. In the cyclone vacuum cleaner, the dust is separated by centrifugal force, so the air moves violently. The air is turbulent, and of course there is a lot of noise, even unpleasant noise. If the sound of the vacuum cleaner will not become louder at high speed, we assume that the internal motor will not change speed when the power is strong. It may be that some additional air ducts are opened inside, causing more air to be sucked in and re discharged. It should be noted that noise is not necessarily related to efficiency. If the design is better, a quieter vacuum cleaner can have better suction.

Which Kind of Best Mute Vacuum Cleaner Should I Choose?
In our test, Electrolux Oxygen z5954 is the quietest vacuum cleaner in both “weak” and “strong” modes. In our test, the noise of the oxygen vacuum cleaner has never reached more than 75 dB. Compared with Dyson, which has reached more than 90 dB, Electrolux oxygen is undoubtedly a quieter and better designed machine.
Japan children’s Fund believes that the oxygen model is the best vacuum cleaner on the market, and we recommend it. One of our staff said, “this machine is very quiet and won’t wake the sleeping baby.” He happened to pass by during the test. In addition, no employee found the sound of Electrolux oxygen unpleasant. Noise is an environmental hazard. The European study recommended 77 DB as the limit. The sound of vacuum cleaner should not be too loud to avoid disturbing neighbors or others. We suggest you try different models of vacuum cleaners before buying.
How to Find the Location of Noise Level of Vacuum Cleaner?
It should be included in the package of the vacuum cleaner, on the box into which the vacuum cleaner enters, or shown on the label as noise level or dB. If there is no description on the label or package, you can check the specification of the vacuum cleaner online or check the user manual. If you still cannot find the decibel of a specific vacuum cleaner, please contact the manufacturer to obtain the official level.

Why Did My Vacuum Cleaner Change From Quiet to Noisy?
If you have a different query, for example, when you first buy a vacuum cleaner, it is quiet. But suddenly the sound became louder? We summarized some skills to find the cause.
- Check the filter
The main reason why vacuum cleaners change from quiet to suddenly noisy is that the filter is dirty. When the filter becomes dirty or blocked, the vacuum cleaner will work harder to remove the dirt, resulting in greater noise. If you pay close attention to your vacuum cleaner, you will find that it also loses power. Then it is best to clean and wait for it to dry completely, or replace the filter, and then check whether the sound is better. Read More: How to Clean a Vacuum Filter
- Blocked hose
If there is foreign matter in the hose, the foreign matter in the hose usually makes a loud sound when air tries to flow through the hose. Your vacuum cleaner doesn’t seem to have suction either. You can disconnect the hose from the vacuum cleaner, thoroughly clean the hose, and make sure that everything inside is outside. Read More: How to Clean A Vacuum Hose
- Check the vacuum fan
If your vacuum cleaner fan is broken or blocked, it may be the reason why it makes more noise. If it is blocked, please clean it and replace the fan if there is any sign of damage.
- Check whether the brush bearing is damaged
When in use, damaged brush bearings usually cause more vibration, making the vacuum sound louder. In order to reduce noise, check whether the brush bearing is damaged and replace it. Nothing annoys you and the people around you more than the loud noise of a vacuum cleaner. If you want to keep calm and enjoy cleaning the room, you’d better know the decibel of the vacuum cleaner. Just remember that the lower the decibel, the quieter the vacuum cleaner will be, so what is safe and what is too loud.
Conclusion
The DB level of vacuum cannot be addressed in a generalized manner. There is a good volume range, though, depending on your circumstance. Loud vacuums are typically either more affordable or more durable. There are several options available if you need a reliable and affordable vacuum. However, you can get something louder than the refrigerator’s buzzing if you don’t mind spending a little more money.
