Never again will I purchase a product without doing some research! Had I come to this site first, I would have NEVER bought this Littermaid! I went on the advise of a young sales girl, who probably doesn't even have a cat, let alone an automatic litter box! I bought it on Monday, and by Wednesday, the litter collector was COMPLETELY FULL AND OVERFLOWING of mostly clean litter, much more of it was on the floor and hardly any in the actual litter box! I have cleaned it all up, am putting it back in the box and returning it tomorrow! It made a HUGE mess!! Very disappointing! Just thankful it was on a tile floor and not carpet!
