Abstract
A multiple fluid conveying hose assembly comprising a principal vacuum conveying hose for a vacuum cleaning system, and a smaller diameter liquid conveying hose passing through its interior. A molded end connector on the principal hose provides an outlet for the smaller hose and serves to separate the ends of the two hoses for use. Alternatively, the hose may utilize reinforcing wire coils which also serve as electrical conductors.
