Robotic pool and spa cleaners work independently from the filter and pump and are driven by an electric motor inside the unit. They are self-contained, collecting debris in a filter canister within the cleaner. Our robotic models come with built-in intelligence to ensure they can’t get caught in corners or stuck on steps, this allows them to provide superior cleaning coverage compared to alternative cleaners. Zodiac robotic pool and spa cleaners are also among the most energy-efficient cleaners on the market.
