Five components are required that make up central vacuum systems that work together. This includes the Power Unit, the Piping System, The Low Voltage System, the Hose, and the Attachments.

The best combination of these components will give you the most effective cleaning, and we’re pleased to assist you in deciding the best option to meet your requirements. 

What Is a Central Vacuum System?

Central vacuum systems are internal systems of vacuum in your home. It is comprised of three major elements:

  • Central vacuum unit
  • Concealed PVC pipes
  • Vacuum accessories

There are generally two types of central vacuum systems that you can choose from:

  • Cyclonic
  • Filtered

Cyclonic systems employ a mysterious force and gravity to segregate contaminants from the air drawn in through the vacuum. The debris is then disposed of in bags or canisters.

Systems that are filtered tend to be more popular with homeowners. It is possible to have either a bag or a non-bag system.

The most crucial difference is that you can clean or replace the filter in your bagged vacuum. Bagless vacuums can self-clean, which reduces the requirement for handheld maintenance.

Central vacuum units are generally located in a far-off place, like your garage, basement, or utility room.

In contrast to the traditional vacuum cleaner, major vacuum systems are not connected to your home. This means you don’t need to worry about dust blowback when you vacuum.

The PVC pipe network is a part of the floors and walls of your house and is also connect to different vacuum outlets.

The system you may be using could begin to turn on instantly or require manual intervention when you connect the pipe.

Whatever is taken in by the vacuum moves through the piping system to the vacuum’s central unit, where you can store debris and dirt. The only thing left to complete is placing your hose back in its storage area.

The Advantages of Central Vacuum Systems

Central vacuum systems are a tremendous option for cleaning. Material, dirt, and dust that are collected are transferred to a single collector unit that seals the particles in the system and stops it from circulating.

The major components of a central vacuum system are:

  • An electric motor.
  • The canister housing.
  • A filtration unit in the form of a filtering system.
  • The exhaust system.

The motor’s dimension determines the system’s performance and how the different elements are arranged.

Whatever way central vacuums are built, They offer a variety of advantages over handheld vacuums. Below is a list of some of the benefits.

Central vacuum systems are a time efficiency, energy-efficient and efficient way to keep work areas neat. They eliminate the need for more cleaning equipment and are easy to access.

The primary kinds that central vacuum systems come in are cyclonic filters and unfiltered bagless.

Different Types of Central Vacuum Systems

1. Bagged:

Bagged Central Systems are the most efficient and clean method to dispose of dust, dirt, and other debris. The suction emitted from the central vacuum system is carried by the dirt and other particles directly into a trash bag, as shown below.

Bags hold dirt, dust, and other debris in addition to 99.9 percent of allergens and microscopic particles. A bag-based system extends the motor’s lifespan and eliminates the requirement for venting the system.

Bags are available in various levels of filtration, including micro-lined, standard, and high-efficiency particulate air (HEPA). They can be purchased in paper or cloth and should be cleaned when the bag is half-full or three-quarters full.

2. Bagless:

Bagless Central Vacuum Systems are simple to operate and cost less to maintain. They function at the highest suction power, even if they empty containers. The system is cleared by releasing the canister and then emptying the contents.

Bagless systems can be equipped with an inverted self-cleaning filter to keep dirt and other debris from getting into the motor.

The filter is moved up to shield the motor if the device is activated. If the system is turned off, the filter is moved downwards, dumping dirt into the canister.

3. Wet/Dry:

Wet and dry central systems can remove dry dirt, dust, and liquid spills. They accomplish everything that a typical central vacuum can do but also being able to eliminate liquids.

Wet and dry vacuum systems connect directly to drains that eliminate the debris, dirt, and liquids into the sewer system. 

This is an unbagged device that is very low maintenance but extremely efficient. There are a variety of applications for Wet/Dry vacuums because they can deal with any spill and obstructions to drains.

4. Cyclonic Systems:

Cyclonic Systems use cyclonic separation to eliminate dust, dirt, and other debris. The majority of the debris gets stored in the canister. The smaller particles are let out.

Cyclonic systems are maintenance-free and do not come with an air filter or bag. It is a model which has been around for a long time.

A cyclonic system can separate dust and particles by spinning them in an enclosed space. The matter spins, and the larger pieces are pushed toward the side of the chamber to drop into the unit for collection. The clean air is forced out through the exhaust connected to the structure’s exterior.

Another aspect of cyclonic systems is filtered and utilizes a pleated filtration cartridge that must be replaced at least once yearly.

The use of a filter within the exhaust system of a cyclonic system guarantees that the exhaust air that exits the system is fresh and free of any contaminants.

5. Filtered:

There are a variety of filters that are employed in central vacuum systems. They include cloth, screen, foam, or paper. Filtered systems are more popular because they can collect dust and debris and then put it in the bin for collection.

6. Compact:

Compact Central Vacuum Systems require minimal or no installation and you can remove it easily. They feature the same suction capabilities as larger ones, with the benefit of moving them easily.

Central Vacuum System Benefits


1. Air Quality:

The central vacuum’s power unit cannot release forced air or create a stir of allergens or dust particles. The Environmental Protection Agency estimates that the central vacuum can significantly decrease dust allergies.

Hence, the air emitted is then disposed of from space for use or released outdoors through an exhaust vent identical to a conventional vent for clothes dryers.

2. Suction Power:

Central vacuum systems are equipped with more powerful motors that provide more cleaning power. Higher suction equals better cleaning, which can eliminate the smallest dust particles. Some systems are equipped with two motors which provide greater suction power.

3. Difficult Debris:

Central vacuum systems eliminate dry materials, like plaster dust, spelled flour, and laser printer toner metal knockout wire clippings, slugs, and fragments from broken glass.

Systems that do not have filters can remove the broadest range of substances, as systems with wet-vacuum interceptors can separate liquids.

All toxic substances, such as asbestos, must be eliminated by specialist equipment, not by the central vacuum system.

4. Emptying:

Central vacuum systems store huge quantities of dust and dirt before it clean, and this can be done less often, like every few months. The particular characteristic of cyclonic systems demands special handling of the canister when you clean it.

5. Noise:

The central vacuum system is extremely quiet because the motor is located far away and is advantageous for the user and others within the vicinity.

6. Convenience:

Setting up, using, and storing the hoses and cleaning equipment is easy and effective. Cleaning stairs is easy with the limited equipment available.

7. Cost:

The initial cost of installing central vacuum systems could be quite high. The only expense that will be ongoing is replacing filters.

There’s no additional cost beyond replacing vacuum lines for systems that don’t have filters. The majority of central vacuum systems work best when they you maintain it regularly. This could be a cost-saving factor.

8. Filtration:

The filtration system is more efficient and can remove large quantities of allergens and dust. The harmful particles are filtered and emitted.

9. Durable:

Central vacuum systems can last for 30 to 40 years. The only required maintenance could be replacing bags, filters, or lubrication of the motor.

10. Tool Compatibility:

The hoses in central vacuum systems can be used with the industry standard tools for handheld vacuum cleaners.

For the United States, the standard dimension is 1 1/4 inches, and the inside diameter is 1 1/4 inches. With certain accessories, it is possible to eliminate excess suction.

11. Security of Furniture and Walls:

Central systems do need any massive equipment that could cause damage to furniture or cause damage to walls.

Then the hose is flexible and is placed inside the outlet. However, a wand handle is held in the hands of the operator. These are the system’s only components within the space that need to be cleaned.

Cons of Central Vacuum System


However, central vacuum systems’ benefits may not be the best choice for your household. Before choosing a central vacuum business to set up your system, you should consider some things.

1. Installation Costs

  • Size of the house
  • Your location
  • The type of system
  • Connectivity is must

2. Storage Space

There are some vacuum systems that come with retractable hoses that can be plugged into the wall when not used. However, some vacuums come with hoses that connect to the vacuum’s inlets.

Although they are helpful for cleaning, they can be quite long and bulky, which can take up space in your home. Without enough space, you’ll need to determine the most suitable place for storing your hoses.

3. Repairs

While it’s not common for central vacuum systems, they occasionally encounter maintenance issues. For instance, damaged motors are one of the main issues homeowners face.

The cost can range from $100 to $500 to repair a damaged motor, not including installation fees.

Other electrical components could cost anywhere from $15 to $55 per hour. If you’re not happy with the occasional costs of maintenance and expenses, then a central vacuum might not be the ideal choice for your household.
