As good an explanation of WHY as any I have seen...
If you are a woodworker and you do any sanding on contoured edges or irregular surfaces, the "Sanding Mop" is the product for you!! This neat little product sands some of the hardest to get at spots. Great for wood moulding, raised panel doors, carvings, bowls, furniture, table legs, restoring antiques... When your option seems to be "I guess I'll have to sand it by hand", let the Sanding Mop do it for you and watch it leave the detail on your piece along with a beautiful finish!
