I am in love with my litter box! We purchased out litter box three years ago and it has worked perfectly every day 365 days a year! Both of our cats are very choosy about their boxes and if the box is slightly dirty the cats wont use them. The Litter Robot keeps the litter clean keeping the cats happy and keeping me happy. With out two cats we have to empty the drawer once a week, they say you should empty it more but ours don’t need it. We recycle plastic grocery bags in the catch bin, they are a tad too small but work fine. I also enjoy the fact that our dogs can’t get into the litter box and help themselves to “the kitty buffet” no one likes kitty poo kisses! I would purchase another in a heart beat! The box seems expensive but for the convenience of not cleaning the litter box multiple times a day and the hardiness of the box I suggest it for every one.
