How a Central Vacuum System Works

The central vacuum system is made up of individual components with each component playing an important role in reducing the owner's workload. The owner doesn't have to carry around a bulky appliance since the motor is stationary. Since the dust and debris are removed from the living area and emitted outside, there's no unpleasant smell or re-circulated dust. The lightweight hose makes it easy to just plug into an inlet and start cleaning. The individual components of a central vacuum system are explored below:

The Core: Vacuum Unit

Central vacuum power unit tanks install in the basement or garage.

Purpose
At the core of the system is the central vacuum power unit. A powerful motor provides strong suction and deep cleaning, while the filter separates debris.

How it Works
The vacuum unit is located in a remote location such as the garage or basement. The vacuum motor pulls air through the pipes and hose, and all the dust, debris, paper, hair, coins, and even small toys accidentally vacuumed are captured and retained in the filter. The exhausted air then is quite clean and is either vented outside or within the area. Depending on the type and capacity of the filter used, it should be replaced every three months to a year. The vacuum is powered on when a vacuum hose is inserted into an inlet within the home. See MD's Power Units.

Options

  1. Filtration. Disposable or permanent filters.
  2. Power. 110 or 240 volt. Units available for every size home.
  3. Quality. Metal or plastic, name brand components or not.
  4. Sound. Ranges from loud to conversational noise level.

The Control: Vacuum Hose

Control suction with the hose.

Purpose
Central vacuum hoses are lightweight, flexible, and crushproof. They come in a variety of lengths, and are the only part of the system taken in hand throughout the home and can be used to clean any surface of the home.

How it Works
Traditional Vacuum Hoses: The long hose has two ends. The wall end gets plugged into one of the vacuum inlet ports throughout the home. Some hoses are designed to cause the suction to start immediately when plugged in. Other hoses are fitted with an on/off switch for the suction on the handle end of the hose.
Hide-A-Hose: This hose is contained in the pipes of the system until it is pulled out for use. When done vacuuming, the hose is retracted back into the pipes by the suction of the vacuum.

Options

  1. Traditional and Hide-A-Hose available in many lengths.
  2. Traditional hose systems can use a variety of hose types.
  3. Electric hose (traditional style) powers electric vacuum head.
  4. Hide-A-Hose available with and without on/off handle switch.


The Connectivity: Pipe and Inlets

Installation pipes and inlets to walls

Purpose
Vacuum Pipe connects the main unit to the wall Inlet Valves. The inlet valves, or ports, connect to the hose and enable the suction to be turned on and off.

How it Works
The two-inch diameter PVC pipe begins at the main unit and splits off into different areas of the house. It goes into a wall and connects to the back of an inlet. One inlet can cover a lot of area, sometimes over 1,000 square feet. A Hide-A-Hose inlet with a 50-foot hose can cover 2,300 square feet. Traditional inlets are available with 110 volts for the use of powerful carpet cleaners; Hide-A-Hose does not have that option. All inlets have a low voltage wire connected that turns the suction unit on-and-off.

Options

  1. Traditional inlets come in a variety of colors and styles.
  2. Traditional inlets available with a 110-volt connection.
  3. Hide-A-Hose inlets come in three colors.
  4. Hide-A-Hose inlets are typically mounted higher.

The Cleaning: Vacuum Tools

Accessories are used to clean every surface.

Purpose
Connecting any of the numerous specialty Vacuum Accessories to the hose allows deep and efficient cleaning on all surfaces of the home.

How it Works There are many different types of accessories available for cleaning any surface in your home. The most common are the two types of carpet brush heads: electric and air-driven. Air-driven brushes utilize the suction to spin the turbine that spins the belt and brush. Electric brushes use a motor to turn the brush, which allows the air to be free to penetrate deep into the carpet. Aside from brushes, there are a variety of other accessories that can be used throughout the home for various purposes, such as de-shedding pets, mopping floors, cleaning blinds, vacuuming cars, and more. These accessories can be attached to the hose itself or to extenders if more length is needed.

Options

  1. Central vacuum accessories for specific tasks.
  2. Complete vacuum accessory kits with vacuum hose.
  3. Combination kits of just accessories alone.
  4. Electric and non-electric accessories.
