Thread: Has anyone used a self cleaning litter tray?

One of the things I've come across in my pre-getting-a-cat research are self cleaning litter trays. They sound brilliant, if they work properly, and I was wondering if any of you had ever tried one?

I've seen some on-line reviews, which seem pretty split between them being really good, or no use at all, but you can't always tell properly from those (some people will always be negative no matter what).

There seem to be two types - one that can be connected to a drain and actually 'flush' the waste away (although they are the most expensive and I know I couldn't have one of those in my house anyway), and others that rake the waste into a sealed container that can then be disposed of when it is full.

Neither type is cheap, so it would be a considerable amount to spend just to try it out (unless there was some sort of money back guarantee).
