"At CES 2026 this week, Roborock launched the Saros Rover, a robot vacuum with articulating legs on wheels that let it climb a full staircase in order to clean multiple floors and also clean each step along the way. I saw a live demo of the Rover on the show floor, and it was impressive. Its legs move in a froglike manner, fluidly and with lots of flexibility."
"As for stairs, it climbed them by using its legs to lift its body, then lowering itself onto the step before pivoting on one leg to vacuum along it. It then proceeded to the next step. The process was fairly slow, taking just under three minutes to climb five stairs, and there were a few moments where it teetered on the edge of a step and I was sure it was going to tumble backwards - but it didn't."
Roborock's Saros Rover is a robot vacuum with articulating wheel-legs that enable full staircase climbing and step-by-step vacuuming for multi-floor cleaning. The legs move in a froglike, flexible manner, raising and lowering independently, performing small jumps, and changing direction smoothly. On stairs, the Rover lifts its body, lowers onto each step, pivots on one leg to vacuum, and proceeds to the next. Climbing five stairs took just under three minutes, with occasional teetering near step edges but no falls. The Rover also navigates slopes smoothly with controlled rolling and braking enabled by its engine.
