Title: not a time or effort saver
Review: I wish I had thought about this purchase a little longer. It takes a large space to work on the sifting, the clumps have to be dumped from a large container into a trash bag, then the litter from one large container to another, after the sifter is reinserted. Clear enough if you look at the picture, yet I didn't really think it through. It is hard to do without spillage, and so can be pretty messy and it seems like a major operation. I'm currently using sifting liners inserted into this contraption and ignoring its sifting capabilities altogether. I find them much easier. And, they keep the box clean. In this, you can't really use a liner and now there are three large pieces that need to be cleaned.
