The Robotic Pool Cleaners are the newer and most advanced automatic pool cleaners which operate independently from your filter system. These robotic pool cleaners are self-contained and carry a bag or cartridge to collect the debris during cleaning. Their electric motors run on low voltage power and plug into a ground fault protected outlet. Most robotic swimming pool cleaners calculate the size of your pool and can clean the entire pool in a short period of time, without revisiting already cleaned areas.
