How Does Central Vacuum Cleaning Work: Things to Know

What Does a Central Vacuum Cleaning System Do?

Any vacuum cleaner only picks up the dirt on the top of the surfaces it’s cleaning. A central vacuum system uses a powerful vacuum system connected to a series of bags or tubes to suck up dirt and dust.

The air is forced out of the bags or tubes into the room. This can be helpful for vacuuming hard-to-reach places, such as under the bed or under a desk.

Dirt trapped in this system can be compressed and stored. This can be helpful for vacuuming things that need to be disposed of, such as sawdust.

This system can help you save a lot of money on your utility bills. Having a powerful vacuum system sucking the dirt out of the room means you can run it less frequently. This can be helpful for noise reduction.

How Does a Central Vacuum System Work?

1) Inlets

A central vacuum system is made up of a number of inlets. There are inlets in the walls, in the ceilings, and under the floors.

The inlets for the central vacuum system are placed in areas of the home where there is the greatest need for cleaning. This can include hallways, stairwells, bedrooms, bathrooms, and even the garage.

2) Vacuum

The central vacuum system is connected to a powerful vacuum that is located in a central area of the home. This is usually in the basement or the attic. All of the inlets connect to the vacuum.

3) Vents

The air that is sucked into the vacuum is then forced out of the home through vents. A central vacuum system can also be connected to a ductless mini-split system. This allows the air to be forced out of vents in the floor.

Potential Central Vacuum Cleaning Problems 

Central vacuum systems can have a number of issues.

The inlets have vents that can become clogged. This can cause problems with the suction for the vacuum. The inlets also can become clogged with dirt, dust, and debris.

If left unattended, it can manifest into physical problems such as:

  • Allergies and Asthma
  • Dust Mites
  • Mold and Mildew
  • Sneezing
  • Itchy eyes and nose
  • Sinus infections
  • Coughing and wheezing
  • Headaches and fatigue
  • Skin irritation
  • Respiratory problems

General Vacuum System Concerns

A central vacuum system can be helpful for cleaning and for reducing the amount of time you spend cleaning the home. However, it can also have problems that cause a lot of stress.

  • Noise: The vacuum that comes with central vacuum systems can be noisy. The noise can be a problem when it’s running.
  • Clog: A clog can be a problem for central vacuum systems. It can cause the system to back up. This can cause a lot of problems that can make the system less useful.
  • Contamination: The air can get contaminated if the vacuum system isn’t maintained properly. Some larger units have filters that can be changed.


If you’re thinking about installing a central vacuum cleaning system, you should be sure to weigh the pros and cons carefully. A professional can help you decide if this system is right for your home or not.
