 It's going to make sure that it gets rid of dirty diapers or the litter box smells. Can't get rid of the actual dirty diapers. That'd be kind of hard. But if you get rid of those odors, and it doesn't take up a bunch of space, doesn't plug into the wall, you don't have to trip over the cord to get to it, and it doesn't take a bunch of air filters either, that's going to save you money too.
