I haven't bought any uncleaned lots in years. By the time they are sold to us they have been cherry picked for the good coins and the low grade ones are put into bag lots for sale. Most turn out to be culls and Constans somethings. Maybe if your lucky something good is overlooked and you get a few nice coins, but for the most part it really isn't worth the time or effort to clean them. Though I must say when I was doing it I enjoyed the process of removing the dirt and uncovering an ancient coin underneath.
