Roborock just demoed a robot vacuum that can climb stairs at CES 2026, and I can’t decide if it’s genius or overkill. The Saros Rover prototype uses articulated wheel-legs to clean steps—finally tackling the last frontier for robot cleaners. But is this the upgrade we’ve been waiting for, or just another pricey gadget chasing a niche problem? Would you trust a robot to tackle your stairs? #Tech #CES2026 #Robotics
