ABSTRACT:
The invention includes a central vacuum system for use in a dwelling. The system features a vacuum unit having an exhaust outlet and a vacuum inlet connected to a fixed gooseneck shaped tube, a flexible cloth hose having a first end and a second end, where the first end is operatively connected to the gooseneck shaped tube with clamping means and the second end contains means for connecting a vacuum attachment. The gooseneck tube contains a flange to engage the clamp attached to the hose so that the hose cannot be pulled from the vacuum system during use. The flexible hose is adapted to extend from the vacuum unit within the dwelling and out through a wall orifice provided to access a living space of the dwelling. The hose is manually collapsible over the tube by a user when the system is not in use.
