The central vacuum cleaning system is a new method of indoor cleaning. It is an integrated system consisting of a vacuum motor, vacuum duct network, vacuum sockets, vacuum hose, and brush heads. Users only need to insert the vacuum hose into a vacuum socket and start the system with a switch. Dust and debris in the workshop will be transported through dust collection pipes embedded in the walls to the vacuum motor located far from the cleanroom. The central vacuum system is equipped with various suction ports, enabling quick cleaning of areas in cleanroom that are difficult to clean using traditional methods.
