Remember to poke holes on the blanket or cloth for the smooth circulation of air. If there is no room for ventilation, the vacuum will overheat and create more problems.

3.Clean the Shop Vac

When was the last time you cleaned you the Shop Vac? Sometimes the cause of the noise could be dirty filers.

The filters are essential for preventing dirt and debris from getting into the vacuum. But continued use without maintenance can cause dirt and debris to get stuck on the filter.

Over time the dirt or debris may damage the motor’s fan causing it to run louder than usual. You may fix the fan by yourself, or you may ask for a professional’s help.

A dirty filter will sound different compared to a clean one.  A dirty filter can also breed a lot of diseases, which is not suitable for you or your family.

  • Start by emptying the contents of the machine. Remove the vacuum’s tank lid. Then place a trach bag at the base of the tank. Empty the contents of the tank on a trash bag. Throw the trash away.
  • Clean the tank using warm water and detergent. Once through, add a cup of bleach then let it sit for 60 minutes. After the one hour, put on some protective gloves and thoroughly scrub the inside of the tank. Then use a garden hose to spray the inside of the tank.
  • Clean the filters as well as using water and soap. The vacuum the top of the shop vac using another vacuum. Then use wipes such as Clorox wipes to wipe the top of the machine. The let the lid dry out in the sun.
  • Remove the hose and its attachments. Then spray clean water and a cleaning product to clean and kill the germs. Then rinse it and let it dry outside.
  • Reassemble the parts then test the vacuum to see if it’s okay.

Remember, regular cleaning and maintenance prolongs the life span of the shop vac and also reduces the noise coming from it.

4. Avoid Using the Vacuum cleaner in a Small Space

Using the Shop Vac in a Small and empty space can multiply its sound. Soundwaves travel through the air towards the wall, and since there are no barriers, the waves bounce back, creating echoes.

Floors and ceilings also reflect sound waves that bounce around to create echoes. So a better solution is using the Shop Vac in open spaces.

You can also fill up the spaces using furniture and paintings. These items absorb noise that would have been reflected to create echoes. In the case of echoes, the furniture will still absorb them easily.

5. Check and Fix Holes and Leaks

Though not common, holes and leaks can be the source of a noisy shop vac. Check for holes on the plastic compartment of your vacuum that can be a canister.

The noise coming from a canister with a hole in it sounds like whistling due to the trapped air. If you hear such a noise, you may need to repair the holes or buy a new one.

6.Unclog the Shop Vac

If your Shop-Vac is making too much noise, then clogs could be the culprit. The vacuum might have sucked up a small object that may be causing the machine to work even harder.

Check inside the pipe to see whether there is an object. If you spot one, try to remove it by hand. You can also use a stick to remove it if you can’t reach it by hand.

If nothing seems to work, take the vacuum to a professional for assistance.

7. Get a Longer Hose for the Vacuum

If your vacuum hose is short, then it means you are close to the noisy vacuum. For this reason, you should consider keeping a reasonable distance between you and the vacuum by getting a longer hose.

Even though the noise will not be eliminated, the effect will not be the same compared to when you were close to it.
