ABSTRACT:
A vacuum hose/fluid line combination is provided for use with a vacuum cleaning system which includes a vacuum canister and heated fluid dispensing apparatus. The vacuum hose is devised with identical swivel cuffs at the ends thereof, each being formed with an opening in the cylindrical wall thereof and arranged to rotatably receive a flexible fluid dispensing line rotatably therethrough. The fluid line is retained within the hose and has its respective ends projecting outwardly through the openings for connection at one end to a hand tool, and at the other end to the fluid dispensing apparatus. Once connected, the vacuum hose is freely rotatable between the connection points.
