Easy Tips on How to Make a Vacuum Cleaner Quieter

We usually set pretty high requirements for household appliances when it comes to the permissible noise level. That is why, if the noise level of a working vacuum cleaner has become much higher, it should be a signal that it requires additional attention.

How loud are vacuum cleaners? Modern vacuum cleaners work with sound ranging up to 85 dB. The main source of noise of the working vacuum cleaner is the engine. Increasing the volume of the running engine indicates that it is running at increased power.

A lot of people from time to time have a problem of dealing with a loud vacuum cleaner. Let’s find out the reasons why your vacuum cleaner is so loud and how to reduce its noise.

How to Reduce Vacuum Cleaner Noise by 50%

Why Is My Vacuum Cleaner So Loud?

The main reasons of why your vacuum cleaner is loud can be:

  • Overfilled vacuum cleaner bag
  • Clogged filters
  • Foreign objects in the vacuum cleaner
  • Technical malfunction and failure of one or more components of the vacuum cleaner.

Let’s dive into the main reasons that may make your vacuum cleaner loud.

Overfilled Vacuum Cleaner Bag

An overflowing vacuum cleaner bag is one of the most common causes of a loud vacuum cleaner, especially for older models. The dust bag can hold a certain amount of garbage and must be changed periodically for disposable dust bags or cleaned (for reusable cloth bags).

The acceptable filling level is around 80% of the volume, then the filtering capacity of the bag is significantly reduced, the suction power drops, and the engine starts to work at the power limit. In modern models of vacuum cleaners, there is a special light indicator that signals an overfilled dust container.

Do not reuse the disposable bag as it has low strength and short service life. It can tear at any time and all debris and dust will fall into the engine compartment, which can cause serious damage. Reusable bags should be washable to improve air permeability.

Clogged Filters

Modern vacuum cleaners have a multi-stage air purification system, while premium vacuum cleaners with HEPA filters are capable of capturing up to 95–99% of impurities. Filters become clogged with the prolonged operation, so your vacuum cleaner will need additional power to allow air to pass through the filters. Some filters can be washed and they will almost completely restore their filtering ability.

Foreign Objects

The traction of the vacuum cleaner may be weakened due to dust, large pieces of paper or debris, toys, or other objects entering the hose that will obstruct the free passage of air.

Technical Malfunction

Loud engine operation may be caused by bearing wear. If the filtration system is not cleaned properly, dry dust enters the engine compartment, settling on moving parts. As a result, the coefficient of friction increases sharply, if the bearings are not lubricated in time, they begin to work virtually “dry”, which leads to their wear. It is much worse if the problem is caused by a faulty winding or component failure. In this case, you will have to contact the service centre.

If the vacuum cleaner was bought recently and a loud sound appeared from the very beginning of the operation, then a manufacturing defect in the engine is likely. Contact the specialists, and according to the warranty card, replacing the device with a new one will be completely free.

How to Reduce Vacuum Cleaner Noise?

If the vacuum cleaner began to make a lot of noise, there is something you can do without calling the service centre.

Be sure to disconnect the vacuum cleaner from the power. To get started, simply disconnect the hose from the vacuum cleaner. If the engine stops making noise, the blockage is either in the hose or in the brush/nozzle. The hose can be cleaned on your own using the cable used by plumbers to clean the sewer. 

In addition, it is necessary to clean the brush, on the fibres of which wool, hair, dust and other debris accumulate. All this leads to the fact that the air is poorly sucked in, the thrust weakens, it is necessary to increase the engine power.

  • If the vacuum cleaner continues to make noise, clean or replace the filters.
  • Clean the chamber in which the dust collector is located. Wipe it with a damp cloth and remove all the debris.
  • Clean all cracks, edges, niches on the body of the vacuum cleaner, where dust can accumulate.
  • Inspect the place where the dust bag is attached. It must be clean, as dust and sand particles will interfere with the tight attachment of the dust bag. Through leaks, dust will enter the motor, causing increased bearing wear.
  • Clean the engine compartment by disconnecting the dust container. In this case, the body must be tilted in different directions, changing the suction power as this will get rid of debris and dust that got into the engine compartment.
  • If after this the engine continues to make noise and does not suck in dust well, you must contact the service centre.

How Do You Unclog a Vacuum Cleaner?

Disconnect the vacuum cleaner hose and check the air draft through the hose openings. If air is being sucked in, the problem may be in the hose itself or in the tube with nozzles. You can clean them without the help of specialists. It is convenient to clean the hose with a cable, which plumbers use when eliminating sewer blockages.

If the problem is with a clogged dust bag, carefully remove it and carefully shake out any accumulated debris.

After washing the dust container, the filter or any part of the vacuum cleaner, dry it well before using it again so that there is no short circuit.

Often clogging occurs due to accumulated debris in the fibres of the carpet brush. Sometimes hair, pet hair, threads and more will get there. As a result, there is a weak draft of air and an increase in the buzz.

Before using the vacuum cleaner, check that all parts are in place, the filters are tight and there are no gaps through which dust can get into the compartment with the motor. In addition, loose parts due to vibration will cause additional noise and may fail over time.

How to Prevent Vacuum Cleaner from Becoming Loud?

To prevent most breakdowns of household appliances, it is enough to follow the rules of their operation:

  • regularly empty the dust bags or change them (if they are disposable);
  • periodically clean filters (or replace);
  • do not allow the liquid to be sucked in if the model is not designed for this.

Compliance with a number of simple rules will prevent the internal parts of the unit from clogging up with dust and will save the engine from overload. This will extend the life of the device and prevent the appearance of unpleasant symptoms such as a loud noise, vibration, shut down during operation.

As you can see, there are some simple steps you can take in order to make your vacuum cleaner quieter. However, if you are not sure of the correctness of your actions, it is better to call a specialist who will deal with the problem of a loud vacuum cleaner and give detailed recommendations on the correct operation of the device.
