The beauty of a robotic cleaner is that they are completely self contained. Robitic cleaners do not work off of the pools circulation system. Robotic cleaners have their own motor and filter. Robotic cleaners have come down in price and have been growing in popularity over the past few years. Are you are sick looking out at your pool only to see a bunch of cleaner hoses? Are you tired of pulling your cleaner out of the corner or off the bottom of the pool when its bag has filled up with leaves? If this is the case or if you are just ready to upgrade to a more effiecent automatic pool cleaner than a robotic cleaner is for you.
