The Scoop Free Classic Self Cleaning Litter box is a good addition to your area.   It is very easy to set up and install the crystal trays.  My cat took a while to get used to the new litter, I had to mix in a bit of his old litter to transfer some of the familiar scent.  The solid waste is whisked away with no problem.  The liquid waste is stirred and does not clump.  This is acceptable for a short amount of time, usually a few days without changing or disposing of the solids.  Very useful for a user of limited mobility as it reduces the scooping.
