How Loud is a Vacuum Cleaner in Decibels (dB)?
At one point, buying a vacuum was a simple process because there weren’t a lot of options. Nowadays, it’s a different story. Different vacuums work best on particular floors or for specific materials. There are even robotic vacuums available now.
However, one of the biggest considerations when purchasing a vacuum cleaner will be its volume. Just like features, there is a sizeable spread of potential volumes. Most vacuum cleaners fall within the 50–80 dB range.
When comparing vacuum cleaners, consider that many of them will have different volumes based on the mode. Some of the more expensive models will have quiet and full-power modes.

Making Sense of dB
So, we know that dB stands for “decibel,” but what does that really mean? How does a dB rating affect us? One thing that puts dB ratings into perspective is that most health and safety authorities recommend hearing protection for anything over 80 dB because long-term exposure can damage your hearing.
Another way we can put this in perspective is to show you a wide range of everyday activities or common things and their dB rating to see where a vacuum cleaner fits in.
|Some insects and bugs||20|
|Quiet office and normal conversation||50–65|
|Average washing machine||78|
Benefits of a Quiet Vacuum
Many factors go into choosing the right vacuum for your needs, such as suction capabilities, filtration, or the location it’s designed for. However, these are secondary considerations to many people.
- No time restrictions: If you live in a multi-family household or there are people with odd schedules, it can be frustrating to figure out when to vacuum. With a quiet machine, this is less of an issue.
- Good for Pets: Some animals aren’t bothered in the slightest by the noise, but it terrifies others. These heightened stress levels aren’t good for animals.
- Good for Humans: In the same way that loud noise can increase stress levels in animals, some studies demonstrate that the same is true for people.
Possible Causes for a Noisy Vacuum Cleaner
Ok, so you’ve opted for the quiet vacuum, and it was wonderful at first, but now it seems as noisy as your last one. Here are a few possible solutions to check before taking it to a vacuum repair shop.
- Dirty filter: Most vacuums have filters. The type will depend on the particular vacuum, but most are cleanable. This is the first thing you should check if your vacuum is noisier than usual.
- Clogged Hose: When a vacuum’s suction is impaired, it causes it to get much louder. A clogged hose could be a reason your vacuum got louder. If your vacuum has a flexible hose, it’s easy to squeeze gently along its length to find any blockage.
- Brush Bearing: A brush bearing is one critical component of the smooth and quiet operation of the vacuum. Quite often, if the brush bearing breaks, your vacuum will get louder and even start to vibrate. You can tackle this if you’re comfortable with a slightly more advanced DIY fix. Otherwise, take it to a repair shop and get it done professionally; it’s not a big job.
- Broken Fan: Over time, as dirt is sucked through it, the fan or fan motor can break, which will increase the sound significantly and impairs the capabilities of the vacuum. This is another advanced repair that is best taken to a professional unless you’re comfortable with the type of repair.

There is no one size fits all answer for the dB level of a vacuum. However, there is a good range of volumes based on your situation. As a rule, the louder vacuums will be either heavier-duty or cheaper.
So, if you need a cheap, hard-working vacuum, there are many options. On the other hand, if you don’t mind spending a bit more money, you can get something that’s barely louder than your fridge’s hum.
