A lot of our readers ask us about the comparison between the Roborock S50 and S55. But the truth is that there is no difference between the Roborock S50 and Roborock S55 except color. It's the same model called Roborock S5, some sellers use the number behind «S5» to represent the color of the robot. On Roborock's official website, the Roborock S5 model is presented in 3 colors, all models available on Amazon (S55 is black, S50 is white, and S51 is white with rose gold elements).
