The Advanced Pro 100 is intuitive and easy to use. At the touch of a button, it gets to work. While it is very small, its ultra-​modern design allows it to clean faster and more efficiently while consuming less energy. An indicator light warns you when the filter is full and needs to be emptied. At the touch of a button, the filter is freed and can be pulled out from above and cleaned all without getting your hands dirty. Its rapid drain system makes it wonderfully easy to remove from the pool. With its on-​board technology, BWT Advanced Pro 100 clings to even the steepest slopes, whatever the waterproofing finish.
