Litter Robot LRII Automatic Self-Cleaning Litter Box, Black
The Litter Robot is the automatic, self cleaning litter box 'that really works'.  When your cat enters the litter chamber (globe) a weight activated sensor detects the presence of your cat.  After 7 minutes a clean cycle starts with the slow rotation of the globe in a counter-clockwise direction.  The rotation of the globe sifts and separates clumps from the clean litter (clumping litter) and deposits all waste in the large capacity drawer lined with a standard kitchen garbage bag.  The globe then returns to its home position with a clean, level bed of litter ready for the next use.  The Litter Robot has no rakes or wires to jam, clog, or break.  Its simplicity and durable construction ensure a long life of service.  The Litter Robot operates on 12VDC and is easy to set up - just add litter to the globe and plug it in.  Backed by an 18 month warranty and 30 day money back guarantee on purchase price.
