Well, at least not much sifting and scooping.  My cats have been using the LitterMaid for a couple of weeks now and I have removed the old stinky litterbox from the room.  I had very little difficulty training the cats to use the new box; I just followed the simple instructions that came with the Littermaid.  The only difficulty I had in getting the cats accustomed to the new box was a teenager who thought it hillarious to yell boo at a cat as it watched the box clean itself.  Needless to say, that cat took a little longer getting used to the LitterMaid and the teenager got the privelege of cleaning the old box.
