The litter robot has been a life saver. I have 7 cats ( 4 are mine and 3 were left by my daughter when she relocated out of the country) and I travel for work. The maintenance of 7 litter pans was pure drudgery. I have had my robot for 3 months and so far so good! I try to empty the waste tray every 2 days because of the volume. One of the cats is older and getting sub-q fluids 3x a week so she makes a lot of urine but emptying the tray is nothing compared to sifting a litter box. It is much healthier for me (no dust) and for the cats because the litter is always clean. I have wasted money in the past on 3 different litter-maid automatic boxes and emptying those trays was almost as bad as sifting litter manually plus the tines would get gummed up and nasty. I am very pleased with the quality of the product and the warranty. Also, its nice to know that I can purchase the parts if needed. I can’t say thank you enough for this great invention. Everybody wins with this product.
