ABSTRACT:
A suction inlet for a central vacuum system of a building includes a housing mounted on the floor of the building and defining a slot along the floor. The slot can be opened and closed and simultaneously a vacuum duct connected to the housing is opened and closed by a plug member. When the plug and the slot are opened, a switch actuates the central vacuum system to draw air into the housing through the slot across the floor so that dust, dirt and debris on the floor can simply be swept into the slot and drawn away.
