After years of wondering when robot vacuums would finally conquer the last frontier of home cleaning, that future has arrived. Roborock unveiled its exciting Saros Rover at CES 2026, and it's everything we've been hoping for—a robot vacuum that can actually climb and clean stairs.

This isn't just another incremental improvement; it's a genuine game-changer for home cleaning. The Rover features articulating legs on wheels that move with surprising grace and fluidity, giving it the ability to navigate multiple floors and clean each step along the way.

Watching the Rover in action is genuinely inspiring. Its froglike leg movements are remarkably smooth and flexible, with each leg operating independently. The little robot can raise and lower itself, perform small hops over obstacles, and change direction with impressive agility—far more gracefully than traditional robot vacuums.

The stair-climbing process showcases impressive engineering. The Rover uses its legs to lift its body, gently lowers itself onto each step, then pivots to vacuum the surface before moving to the next one. While it takes about three minutes to climb five stairs—working carefully and methodically—the technology demonstrates real promise for thorough home cleaning.

Beyond stairs, the Rover successfully navigates slopes with controlled precision. Its advanced engine allows it to brake, stop, turn around, and even move backward up inclines. Perhaps most delightfully, it can perform small hops to jump over multi-level room thresholds, meaning fewer barriers between your robot and a completely clean home.

Roborock envisions the Rover tackling almost any staircase configuration—traditional, curved, spiral, and even carpeted stairs with bullnose fronts. This versatility means the robot could potentially access every room in your house, making whole-home cleaning finally achievable without human intervention.

The company is taking a thoughtful approach to bringing this innovation to market. Rather than rushing, Roborock is ensuring the product meets high standards before launch. They're currently exploring which mopping system would work best with the Rover's unique design, showing their commitment to delivering a truly complete cleaning solution.

This development represents more than just a clever gadget—it signals how rapidly home robotics technology is advancing to serve real human needs. From simple disc-shaped vacuums that just pushed dirt around to sophisticated machines that can navigate complex environments, we're witnessing the evolution of truly helpful home assistants.

For people with mobility challenges, multi-story homes, or simply busy lives, the Rover offers hope for maintaining clean, healthy living spaces more easily. It's particularly exciting for families who've struggled with keeping stairs clean—a task that's often overlooked but important for home hygiene.

While the Rover is still in development, its demonstration proves that the technology works. This isn't science fiction anymore; it's the near future of home care, bringing us closer to homes that can maintain themselves while we focus on what matters most to us.

The journey from ground-level cleaning robots to stair-climbing helpers shows how innovation continues making our daily lives better, one step at a time.
