Why Do Vacuums Suck?

The vacuum cleaner was invented to solve the problem of having a dirty surface. A vacuum works because of a difference of air pressure that it causes. It has an electric fan with rotating blades that forces air forward. This causes the air pressure behind the fan to drop. Since the pressure inside the vacuum is lower than the air pressure outside of the vacuum, filtered air that is housed inside gets pushed out. Dirty air and small particles outside the vacuum are simultaneously suctioned and trapped inside because of friction.

Reasons That Your Vacuum Doesn’t Suck Anymore

The most common reasons for a vacuum to lose suction include:

  1. Dirty Filter
  2. Clogged hose
  3. Vacuum pieces not sealed
  4. Airbrush blocked
  5. Full bag or container

1. A vacuum cleaner usually has two filters: exhaust and air intake. If either of these filters is dirty, the vacuum won’t be able to create the air pressure change and, therefore, can’t cause friction or suction. Make sure to clean your filter regularly. Most filters are made to be washed, but check the owner’s manual. If your manual advises against washing it, you can simply bump it against a hard surface to get rid of the debris. If you wait until the filter has been damaged, it will have to be replaced.

2. If there is an obstruction in your vacuum hose, this is a very obvious reason that your vacuum won’t be able to suck anything up. Home Guides gives one simple way to tell if this is a problem: shine a flashlight through one end of your hose. If you can see the light from the other end, you will know that this isn’t the issue.

3. Sometimes a vacuum not sucking can be as simple as one of the pieces not being sealed tightly. There are many parts of a vacuum and each must be securely fastened in order for the friction and suction to work. Check your manual and make sure each piece is intact and that there are no cracks or holes anywhere on the vacuum, especially between the hose and the vacuum.

4. Another common problem with a vacuum cleaner losing suction is that you may have tried to suck something up that was too large to fit through the airbrush section. You can tip the vacuum over on it’s back or side and check to see if there are any objects too large to fit under or above the airbrush. There might also be too much hair gathered up around the airbrush that is causing it to lose friction. The airbrush can generally be removed and cleaned.

5. One major reason for a vacuum losing its suction that a lot of people forget about is the fact that your bag or container might be too full. Remember to replace your bags often or empty your container frequently. One article suggests changing the bag when it is halfway full.

What To Do When Your Vacuum Doesn’t Suck Anymore

First, try all of the methods suggested above for checking each of the common reasons for a vacuum losing suction. You must ensure that your filters are clean, there is no obstruction in your hose, all pieces of the vacuum are sealed tight, the airbrush area is clear, and the bag is replaced. If you’ve checked all of these things and the vacuum doesn’t suck, then it might be time to consider bringing it in. We can check the vacuum to see if there are any other issues that might be occurring to cause the vacuum to lose suction.
