The black tube attached to the hose on my MultiFloor 2 fits into the purple piece (yellow on my machine) shown in the drawing below. What holds these two pieces together when you want to use the hose for cleaning drapes or upholstery, etc. On mine, the tube just falls out of the purple piece (at the blue arrow) whenever I want to use it. It seems like I must be missing some sort of clip that holds the two pieces together. No amount of force will join them together so that they “click” into place.
