I am carefully following the CES 2025 in Las Vegas, many innovations introduced by manufacturers, including mechanical arms, self-cleaning track or roller washing systems, hot washing, new navigation systems and the evolution of AI. As I expected, I don't think the "perfect robot" was presented, but a whole series of technologies that could, if used together, create one. X50 Ultra is definitely a step forward in this direction, waiting for the arrival at Dreame of the self-cleaning roller/track washing system and the possibility of washing corners too, a point that all robots today still leave uncovered.
