This is the most important component of any vacuum system. It basically consists of a motor along with a separate filter. When a powerful motor is essential for deep cleaning, as it will enhance the suction-ability of the overall vacuum system, the filter comes handy for separating the dirt from debris.

Pipes & Inlet Valves

Nowadays, the manufacturers usually opt for PVC pipes when it comes to installing a central vacuuming system. The main purpose of these pipes is to connect the power unit, which is located in a remote location, to the lightweight hose.

Starting from the main power unit, the pipes split into different parts. Each of these pipes goes into different walls around your home and connects to a separate inlet valve. These valves, as already mentioned, are further connected to the vacuum hoses. Depending on the length of your hose, each inlet valve can cover a considerable amount of cleaning area which can go as high as up to 1000sqft.


Available in a wide range of lengths, the hoses of the central vacuum cleaners are incredibly lightweight & extremely flexible. You can work with them for an extended duration of time and they won’t cast any fatigue on your body. Moreover, some of these hoses are also crushproof which means that you can use them for an extended period.

As per its working, a hose basically consists of two different ends. One of them gets connected to the inlet valve and the other one is used to suck dirt, debris, and other such accessories.

Nowadays, there are two types of hoses which are available in the market. One of them gets instantly turned on when you connect it with the receptacles so you can start vacuuming straightaway. As per the other type, it is provided with a separate on/off switch.

The hoses are designed in such a way that once you’re done vacuuming, they will be fetched back into the wall-mounted receptacles. Also known as Hide-A-Hose, it is a convenient mechanism for all those homeowners who don’t want to deteriorate the look of their living rooms with a vacuum hose being constantly placed on one side.

Vacuum Brush

A tool which is connected at one end of the hose, the basic purpose of a vacuum brush is to ensure efficient cleaning. There are two types of vacuum brushes which are commonly used in the Central Vacuum System. When one of them is the Air-driven brush, the other type is an electric brush. Even though the air-driven brushes are the most famous types with a vast majority of customers, you can also choose electric brushes for this purpose.

    I really like how you say that a central vacuum doesn’t have an electric cord, so you won’t trip over it. I’m always falling over and struggling with the cord. My husband and I are remodeling a nice home for ourselves and our two toddlers. Having a good way to keep clean is really important for me, so I think that I’ll find someone who’ll install a central vacuum for us.
