What is a central vacuum system ?
A central vacuum system is a built-in cleaning system that provides a convenient and powerful alternative to portable vacuum cleaners. It consists of a central power unit typically located in a basement, garage, or utility room, connected to a network of pipes installed within the walls of a home or building. Wall inlets are strategically placed throughout the space, allowing users to attach a lightweight hose (usually about 9 meters long) and cleaning attachments.


Central Vacuum Power Unit
A Central Vacuum Power Unit is the main component of a central vacuum system. It houses the motor, filtration system, and dust collection container or bag. This unit is responsible for generating the powerful suction that draws dirt, dust, and debris through the system and into the dust collection container.
Key Features of a Central Vacuum Power Unit:
- Motor: Provides the suction power needed to clean efficiently.
- Filtration System: Traps dust, allergens, and other particles to ensure clean air is exhausted.
- Dust Collection: Stores the collected debris until it is emptied, either in a bag or a canister.
Installation Location:
The power unit is typically installed in a remote location within your home or commercial building to keep noise levels down and free up living or working space. Common installation spots include:
- Garage: Convenient for disposal of collected debris and noise reduction.
- Utility Room: Another popular choice, providing a central location that is often away from living areas.
Central Vacuum Wall Inlets Covers
A central vacuum inlet cover is a component of a central vacuum system. It serves as the access point where a vacuum hose is connected to the system. These covers are typically installed on the walls of a home or building and protect the vacuum inlet valve when not in use, ensuring the system remains sealed and clean.
Key Features:
- Protective Seal: Prevents dirt, dust, and debris from entering the central vacuum piping when the system isn’t in use.
- Design: Often designed to blend seamlessly with wall décor.
- Automatic Switch: Many inlet covers activate the vacuum system when the hose is inserted.
Common Installation Locations:
- Living Rooms
- Bedrooms
- Hallways
- Kitchens
- Basements
- Garages
These inlets are strategically placed throughout the building to provide easy access to the central vacuum system, minimizing the need for long hoses and maximizing cleaning efficiency.


Pipe System
PVC 50.2 mm pipes (installed in the floors and walls) connect the inlets to the central unit, carrying debris and air to the collection canister.
Materials Needed
- PVC Piping: Central vacuum-grade pipes (lightweight, durable, and static-free).
- Fittings: Elbows, couplings, and Y-fittings for routing.
- Pipe Straps and Mounts: To secure pipes in place.
- Drill and Core Bits: For cutting through concrete walls and floors.
- Sealing Materials: Silicone or cement-based sealant to secure pipe penetrations in concrete.
- Inlet Valves: For connection points throughout the home.
A well-installed central vacuum system in concrete homes adds immense value and convenience. With proper planning and execution, the system will offer seamless, powerful, and durable cleaning capabilities for years to come.
Exhaust System
A central vacuum exhaust system is an essential component of a central vacuum system that ensures clean, healthy air in the living space by expelling vacuumed air outside the home or into a designated exhaust vent. Here’s a detailed breakdown:
External Venting:
- The exhaust is typically vented through a duct leading to an exterior wall or roof vent.
- This prevents accumulation of allergens and ensures indoor air remains clean.
Noise Reduction:
- By venting outside, the system also reduces noise within the home, as the motor and air movement noise are minimized in living areas.


Standard Attachments
Central vacuum systems come with a wide range of attachments and accessories designed to make cleaning more efficient and versatile. Here’s a breakdown of some commonly available attachments:
- Dusting Brush: Ideal for delicate surfaces like blinds, shelves.
- Upholstery Brush: Perfect for cleaning furniture, curtains, and cushions.
- Crevice Tool: Long, narrow tools designed to clean tight spaces.
- Hard Floor Brush: Specialized for tile, hardwood, or laminate flooring.
- Combination Floor Tool: Switches between carpet and hard floor cleaning modes.
- Extension Wands: Allow extended reach for high or low cleaning.
- Accessories Bag: A handy storage solution for keeping all attachments and tools organized and easily accessible.
Hose Hanger: A practical accessory to neatly store the central vacuum hose when not in use.
