There is not much that can clog with the mini, so I guess you mean the hose. First, you can detach the elbow fitting. Pull it out of the vac, it's a friction fit, and then you can take it off the hose. On the side of the elbow fitting are two small tabs you have to push in with a small screwdriver, and the retainer ring will come loose. When you get it off, use a piece of electrical wiring or a long thin dowel and shove it through the hose to unclog it. Simply sweeping it around might also work.
