The "final frontier" of home robotics has officially been crossed at CES 2026 in Las Vegas. On January 6, 2026, Roborock stunned the tech world by unveiling the Saros Rover, a revolutionary vacuum that finally solves the industry’s oldest problem: stairs. While previous attempts at stair-climbing relied on clunky treads or secondary "carrier" units, the Saros Rover uses a proprietary wheel-leg architecture. Each of its articulated limbs can lift, reach, and pivot independently, allowing the robot to "walk" up a staircase one step at a time with human-like agility. Most impressively, live demonstrations showed the Rover actively cleaning each tread as it ascended, ensuring that the entire multi-story home is covered in a single session without human intervention. Under the hood, the Saros Rover is powered by the StarSight Autonomous System 2.0, which utilizes 3D spatial sensors and AI to calculate the exact height and depth of steps in real-time. Whether it’s traditional straight stair...
