Click the "Select Control Object" and select the dummy (or point) controller next to the vertex. Now, when you move that control dummy, only that one vertex of the line will move with it. You can repeat the process for each vertex of the line (i.e. add an Edit Spline to the stack and select the next vertex, then add a LinkedXForm modifier and link to the next control object.) You can then link the control dummies to other objects (like your vacuum) to drive the animation, or you can animate the dummies directly, and the line (tube) will follow the dummies. Make sure the vertex directly below each LinkedXForm modifier in the stack stays selected, or it won't work.
