Cental Vacuum Cleaning
A central vacuum cleaner (also known as built-in or ducted) is a type of vacuum cleaner appliance, installed into a building as a semi-permanent fixture. Central vacuum systems are designed to remove dirt and debris from homes and buildings, sending dirt particles through tubing installed inside the walls to a collection container in a remote utility space. The power unit is a permanent fixture, typically installed in a basement, garage, or storage room, along with the collection container. Inlets are installed in walls throughout the building that attach to power hoses and other central vacuum accessories to remove dust, particles, and small debris from interior rooms. Most power hoses typically have a power switch located on the handle.
