As CES 2026 kicks off, the best robot vacuums and innovative robot mops are expected to be a hot topic this year. And Roborock seems to be paving the way in innovation and design with its latest offering.

The brand has just unveiled the Rororock Saros Rover — the “world's first” two-wheel legged robot vacuum that can climb up and easily navigate flights of stairs. And while the Saros Rover looks like something out of a sci-fi movie, this two-wheel-leg architecture is designed to mimic human mobility to tackle multi-story homes, slopes, and inaccessible areas with ease. It can even jump in mid-air.
Sounds too good to be true? We saw the Saros Rover in action at CES, and came away pretty impressed.
Two-wheeled legs to navigate over high thresholds
Perhaps the key highlight is that the Saros Rover is the first of its kind to have two-wheel-leg architecture. This enables the robovac to navigate over steps, high thresholds, and awkward spaces.
And while we’ve already seen previous robovac models with an extendable arm or adapt-lift chassis, such as the Roborock Saros 10, the Saros Rover is designed to mimic human movement for a more sturdy and reliable clean.
How it works
In order to climb stairs, the Rover first raises itself on its two wheels; in their extended position, the bulk of the vacuum is in the front. It then rolls itself forward so that the vacuum is resting on the first step.
The wheels then retract backwards and up — it reminded me of a frog's legs — before tucking back into the vacuum's body.
The Rover can control each leg independently, so it can actually clean your stairs as it goes up. We saw it extend one leg, turn to the side, and then vacuum a single stair tread before retracting the leg and continuing its journey.
This capability even allows the Rover to jump up and down; it's not something we'd imagine it would have to do in real life, but it was fun to watch.
It can tackle slopes and non-flat surfaces
Another ground-breaking feature is the ability to climb flights of stairs and clean each step without toppling over. What’s more, this includes a curved staircase, which is often problematic to navigate. This feature is beneficial when cleaning multi-story homes that require the correct height adjustment to deep clean. In addition, the Saros Rover can tackle various non-flat surfaces with ease due to its flexibility.
It has advanced 3D spacial awareness
Of course, the Saros Rover is packed with the latest tech and AI software to make the robotvac more powerful, precise, and its wheel-legs reactive to the environment. This includes using Artificial Intelligence algorithms, alongside advanced motion sensors and 3D spatial information.
For instance, the Saros Rover reduces "no-go" zones by accessing areas previously off-limits to a single robot vacuum, making it ideal for multi-story homes. Plus, it can transition to and clean the second floor by tackling each step of a staircase — which not many robot vacuums can do successfully.
Availability and outlook
Roborock would not give any specifics over the future availability or price for the Saros Rover, only that it was expected to come out sometime in the near future; a company representative said that they need to get the technology perfected first.
When it does arrive, though, it could make a real difference for those who don't live in a ranch home and want a single robot vacuum to be able to clean their entire house.
