We have tried one of those. It did not work well with our cats.

Here are a few reasons:
1. it probably would be okay with 1 cat, but our 4 cats were a bit much for it
2. it got caught in the cleaning cycle, for several minutes, trying to clean and clean and clean
3. our cats like to dig, and the litter was only about an inch deep, too shallow for our cats

We are currently using manual litter boxes, they are cleaned by a
faithful man-servent (me ) each day.
