Roombas also come equipped with color-changing LEDs that indicate things like remaining battery power and dirty spots. The LED lights combined with a seemingly random cleaning path has led some intrepid photographers to take long exposure photographs. The results, a kind of ‘light painting’ are mesmerizing.
Some artists have even taken the idea a step further, using multiple roombas in a single room or affixing various colored LEDs to the Roomba to garner a multitude of results. And with no two Roomba paths being the same, the possibilities are endless.
