The Dolphin Sigma can clean the floors, walls, and waterline of your swimming pool. To do this, it relies on an extra large filter, which makes it easier for larger quantities of material to be removed. Neither of these features can be found in the Dolphin Nautilus CC Plus, which makes for a less elaborate pool cleaning process.
