What is a centralised vacuum cleaner?

A centralised vacuum cleaner, also known as a central vacuum system, is a type of vacuum system that is installed within a building, where the main unit is typically located in a basement or utility room. It uses a network of pipes installed inside the walls to connect various inlets located throughout the home. Users can plug a vacuum hose into these inlets to clean different areas without needing to carry a traditional vacuum cleaner around. This system is known for being quieter and more powerful than portable vacuums, while also improving indoor air quality by expelling dust and allergens outside the living space.
