From The Manufacturer
The Legend pressure-side cleaner features a highly efficient booster pump (sold separately) for optimum power and unimpeded surface skimming, plus a large intake throat to handle large and small debris. The Legend is also designed for traction and stability, so it keeps on cleaning when the terrain gets tough. When you want your pool cleaned quickly and completely, count on the Kreepy Krauly Legend cleaner. A host of design features combine to keep the Legend cleaner on the move, thoroughly cleaning most pools in just one to three hours.
