Letro Legend automatic pool cleaners are pressure side cleaners, which means water pressure is used to propel the cleaner around your swimming pool and draw debris from the pool into a filter bag. Some popular models of Letro cleaners are the Letro Legend, Letro Legend II and Letro Platinum. Letro pool cleaners feature four wheels for better stability, and a large volume debris throat and debris bag. Dual drive wheels and thrust jets are used to propel the Letro pool cleaners, instead of a gear and/or belt drive system used on other pressure side cleaners.
