We just bought a house and the master bedroom has wool carpet in it and I just wanted to know how to clean it!!
Wool carpet looks and feels awesome, but is tougher to maintain. I would not use a general carpet shampoo on it since they tend to be rough on non-synthetic fibers over time. For spot treating (spills, etc): Use a white cloth dampened with barely warm water and a few drops of clear dish washing liquid. White cloth and clear liquid just to make sure there's no color/chemical transfer. Blot it the way you'd get at any spill and then a dry cloth to get all that water up. For a deep clean: You'll be better off getting a professional in once a year or whenever the mess is too big to clean yourself.
