@indigomoth - Well, on the other hand, there are jobs created because someone has to maintain the pool cleaners. Any kind of automatic inground pool cleaner is going to need regular maintenance because you won't believe the kinds of stuff that end up in swimming pools.
Our pool cleaner seemed to break down almost as regularly as we would have had someone in to clean it. And even with a pool cleaner, we still got someone to give it a thorough clean every now and then.
Having a pool is expensive either way and it creates plenty of jobs, automatic cleaner or no automatic cleaner.
