I saw a two-legged Roborock that is rocking the robot vacuum market at CES 2026

Robot vacuums just learned to walk upstairs. Roborock unveiled its Saros Rover at CES 2025, featuring what the company calls "wheel-leg architecture" that allows the device to extend foldable legs and lift its body nearly a foot off the ground. This breakthrough enables the vacuum to navigate stairs independently, cleaning each step as it goes while moving between floors without human intervention. The robot uses artificial intelligence algorithms processing motion sensors and 3D spatial data to execute jumps, sudden stops, and body tilts to avoid obstacles. While Roborock hasn't announced pricing or availability dates for the stair-climbing Rover, the company is launching three new traditional robot vacuums in 2026, including models with market-leading 35,000Pa suction power. The tech giant is also bringing its robot lawn mowers to the US market for the first time, expanding beyond indoor cleaning into yard care with models featuring RTK navigation and LiDAR technology.
