How ironic then, because I personally found Roomba robots extremely dumb, until quite recently at least, most of their models roamed randomly, with almost no planning. On the other hand Neato Robots are so much better, they cover the surface width planification and mechanical precision. Now baseless speculation: I wouldn’t be surprised to learn that a large part of this difference is due to the fact that a company used Lisp because of ideology, while the other company used a language which is actually leading currently in robotics, (c++ or Python) because of practical reasons: they could harness the massive ecosystem to make stuff that are actually useful instead of recoding a robot OS in lisp.
