Query: DOESN'T WORK

when i got the littermaid i loved it for about 3 days. then it began clogging up and getting disgustingly dirty. NO ONE i've ever met, and i do animal rescue work, has ever kept this and used it beyond a month.want to get one that really works? go to http://litter-robot.com/ and check out the message board at http://www.litterbox-central.com this was a great resource for me. i was obsessed with finding a solution to the litterbox oder and time it took. litter robot has been a great product for me...for now nearly a year and on the litterbox central forum you can see testimonials from other users who are happy for longer. 3 weeks for this crummy littermaid or a 18mth warrenty and many happy users with the LITTER-ROBOT. littermaid is not the only solution. get a litter-robot and be happy :)
