We kept the vacuum motor from HOBOT-188, but added two additional cleaning wheels, increasing moving speed to 4,7 inch per second, significantly reducing cleaning time of large surfaces. Due to the addition of a new generation of microfiber cloths and a double passage of each glass, the cleaning quality is on par with the legendary HOBOT-188.
