Packed with even more features and exceptional cleaning power, the Nautilus Plus with CleverClean is a must have for any pool up to 50 feet in length. This upgraded cleaner features CleverClean Technology, a software that systematically scans your pool to determine the most efficient path, regardless of the shape or surface of your pool, resulting in a clean pool every time. The weekly timer function allows the Nautilus Plus with CleverClean to automatically run its programmed two-hour cycle at set intervals throughout the week. The extra-large top access filter system is equipped with two full sets of filter cartridges. This means that both large and small debris will be filtered out from your water, resulting in a cleaner, clearer swimming pool. One of the most defining features of Dolphin robots is the presence of a patented swivel cable. This technology addresses one of the most prevalent problems with robotic cleaner technology by allowing the cable to spin and rotate a full 360 degrees with the robot’s movement in the water, without the cable becoming kinked or tangled. Another important feature to note about Dolphin Robotics is the fact that it is completely independent of you pool’s pump and filter, enabling you to clean your pool using a fraction of the energy than other types of cleaning systems. The Nautilus Plus with CleverClean is also backed with a 24 month warranty leaving you worry free.
