Once a province of standard leaf skimmers and manual labour, pool cleaning is now largely carried out by smart gadgets. Decades of research and development in robotics gave birth to pool cleaners that cover every nook and cranny in pools of any size or shape. In fact, such robotic pool cleaners are capable of scaling the walls, up to the waterline.
The concept of automatic pool cleaning dates back to the 1960s in the U.S. Andrew Pansini of Greenbrae, California is credited with inventing the first patented automatic pool cleaner. His invention dislodged dirt and grime, leaving them in the water for the pool pump and filters to remove.
