Why Are Vacuums So Loud? (12 Reasons Why Your Vacuum Is Getting Louder)

Why are vacuum cleaners so loud?

There are several reasons why vacuum cleaners are loud. First and foremost because they have powerful motors that allow air to flow through the machine at a high speed. It’s this rapid airflow that sucks up dirt and debris from your carpets. This airflow is also responsible for most of the noise from your vacuum cleaner.

The other reason vacuum cleaners are so loud is because of the way they are designed. Most vacuum cleaners have metal fan blades that produce an intense, high-pitched whine when spinning quickly. The motor in a vacuum cleaner is also made of metal, which can produce an extra loud noise when running.

Since most vacuum cleaners today use large motors and metal fan blades in their construction, noise pollution is almost inevitable. However, there are some things you can do to reduce the amount of noise your vacuum cleaner produces. One of these things is to make sure your machine has a good quality muffler.


12 Reasons Your Vacuum Is Louder Than It Should Be

If your vacuum cleaner makes an annoying noise when you turn it on, there may be something wrong with your machine. But don’t worry, there are plenty of things you can do to fix the problem before buying a replacement.

1. The motors in the most inexpensive vacuum cleaners are not designed for efficiency

They rotate so fast and use so much electricity that they generate a lot of heat. If you’ve ever noticed how hot your vacuum gets when you use it a lot, now you know why: It burns all that extra energy as heat because it doesn’t have an efficient way to make it work.

2. No noise reduction systems at all to muffle them

Some upright vacuums have mufflers on their exhaust ports that reduce some of the noise that comes out, but they don’t reduce much of the motor noise or vibration noise in the vacuum itself. Only a handful of expensive vacuum cleaners have noise-dampening liners in their bodies (like cars) or other active noise canceling systems (like headphones).

3. You have a full vacuum bag

When your vacuum bag is full, it will restrict airflow, increasing the power consumption of the motor. This causes your engine to work harder, require more energy and make more noise.


4. The brush roll is set too low

If the brush roll is too close to the floor, it will make more noise when it hits the floor while cleaning.

Hair or dirt is wrapped around the brush roller. If there is hair or dirt around the agitator bristles of your vacuum cleaner’s brush roll, it can cause quite a bit of noise when vacuuming.

5. You have a hard floor

If you have hard floors in your home instead of carpeting, you will definitely notice an increase in noise level when you use your upright vacuum. This is due to the fact that with hard floors there is nothing that can absorb the extra sound energy from your machine!

6. You may need a new belt

The belt on your vacuum determines how quickly and how smoothly the brush roll spins while cleaning up dirt and grime on your carpet or floor. The belt may not be broken, but it may have stretched over time causing it to slip more often than usual and make a loud squeaking noise while vacuuming.

7. Your vacuum cleaner is clogged with dirt or debris

Over time, dirt and grime can get trapped in your vacuum cleaner hoses or filters, preventing air from flowing properly through the system and creating a constant noise loud enough to be heard throughout your home. This can also cause your vacuum cleaner to lose suction as there is no airflow flowing smoothly through the system.

8. Motor mount loose or broken

Your engine should be mounted securely to avoid vibration and reduce noise. If your engine mount is loose or broken, make sure to repair it right away so you don’t damage your engine or belt.

9. The vacuum cleaner needs to be cleaned

Your vacuum cleaner may need to be cleaned. The roller brush in the vacuum cleaner’s cleaning head is usually driven by a belt, which can wear out if dirt gets under it, disrupting the alignment of your belt. And as the belt wears, it can slip and make a squeaking noise.


10. You have the wrong vacuum cleaner for your floor

Some vacuums work better on different floors than others, but you can also choose the attachment that’s right for your floor. If you use a hardwood floor attachment on carpeted floors or vice versa, your vacuum cleaner may be noisy.

11. You are using the wrong beater bar height

If you are using a beater bar brush roll on carpeted floors, adjust the beater bar to the correct height for the carpet pile before you start vacuuming. If you adjust it for deep pile carpet when cleaning short pile carpet, the vacuum cleaner will work harder and make more noise.

12. Something is stuck in the brush roll

If fibers from your carpet or hair are wrapped around your brush roll, it can cause it to get stuck and make a noise when it tries to spin. Check your roller brush regularly for dirt and clean it regularly.


In summary, the way most vacuum cleaners work is by drawing air through a filter. The air passes through the machine and pushes dirt, dust and particles from the vacuum through the hose. This process creates a pressure imbalance that makes noise.

The harder you suck, the louder the machine gets. That’s why you’ll find that your vacuum cleaner is loudest when you’re trying to pick up stubborn dirt or hair.

However, a vacuum cleaner doesn’t have to be that loud. Many vacuum cleaners are not even as loud as their predecessors – in some cases they are almost silent.
