Vacuum makes loud noise: what could it be?

Vacuum makes loud noise

While you are vacuuming, your vacuum cleaner suddenly makes a lot of noise. Don’t be scared! There can be several reasons why a vacuum cleaner suddenly makes a louder noise than normal. For example, a filter may be clogged or the dust bag needs to be replaced.

In this article I would like to help you further! Let’s see why your vacuum cleaner makes a loud noise and how we can solve this (quickly).

Why does a vacuum cleaner sound louder than normal?

When a vacuum cleaner suddenly makes more noise than usual out of nowhere, something is wrong. Often it is a problem with the airflow: the vacuum cleaner parts do not connect properly or there is a blockage in your vacuum cleaner.

However, it can also be a defective part. For example, a part of the vacuum cleaner motor may be broken, which can cause a rattling sound. Different types of sounds that can suddenly be heard:

  • Ratteling noise
  • Beeping noise
  • Humming noise
  • Grinding noise
  • Scratching noise
  • Whistling noise

Some also sometimes speak of a screaming or sighing sound. In any case, it is all about a loud, annoying sound.

Common causes for a loud sound

The type of sound you can hear depends on the problem. If there is a blockage somewhere in your vacuum cleaner, there is a good chance that you will hear a squeaking sound, because the air can not pass properly. The most common causes at a glance:

  • A blockage in the vacuum cleaner (vacuum not sucking)
  • A full dust container
  • An old or dirty HEPA filter
  • A worn part
  • An air leak
  • A faulty vacuum cleaner motor (for example, a broken fan)

This is how you get the vacuum cleaner quieter again

Time to fix that annoying noise, because a vacuum cleaner makes enough noise itself! You can probably solve the loud noise problem yourself with the tips below.

  • Empty the dust container or replace the dust bag with a new one
  • Check the vacuum cleaner for blockages, view tips here if your vacuum hose is clogged
  • Clean the HEPA filter or replace it with a new one
  • Check the vacuum cleaner for air leakage and seal it with silicone tape if possible

Do the above tips not help and does your vacuum cleaner continue to make a loud noise? Then stop using the vacuum cleaner: there may be a defective part. Feel free to message me so I may be able to help troubleshoot the issue.
