Roborock Shows Stair Climbing Robot Vacuum at CES 2026, Focus on Mobility and Corner Cleaning

JAKARTA - Roborock showed a major leap in robot vacuum technology at the CES 2026 event by presenting the Saros 20 line. This is an autonomous floor cleaning device that is not only more powerful, but also more agile. The main highlight comes from the ability to suck up to 35,000 Pa, cleaning the corners of the floor with precision, to a prototype robot that is claimed to be able to climb stairs.

For years, the robot vacuum industry has been stagnant, with suction power improvements often feeling cosmetic. However, this year's Roborock exhibition shows a shift in a more grounded direction: mobility. Instead of just adding pascal numbers, Roborock targets the real problems of modern homes, from floor level differences to narrow corners that are often missed.

The two flagship models, Saros 20 and Saros 20 Sonic, are both equipped with a suction power of 35,000 Pa, about 60 percent higher than the previous generation of high-end models. The key differentiator is the AdaptiLift Chassis 3.0, a chassis system with a special arm that allows the robot to climb obstacles up to 3.3 inches high. For homes with thick doorways or multi-level living rooms, this feature turns an area that was previously "off-limits" into a cleanable area.

The chassis can also adjust its height automatically, so that the robot can lift its body when cleaning thick carpets without losing suction power or getting stuck. The point is, the robot is no longer just smart, but also adaptive.

The Saros 20 Sonic variant specifically targets users who prioritize the pel function. Relying on the VibraRise 5.0 system that vibrates up to 4,000 times per minute, the pel head can now extend out of the main body. This answers the classic problem of round-shaped robot vacuums: dirty lines along the walls and furniture legs that are difficult to reach.

Roborock also introduced the Qrevo Curv 2 Flow, a model with a roller-shaped roller that rotates at 220 RPM and applies pressure to the floor, mimicking manual scrubbing movements. Its main advantage lies in the real-time self-cleaning system.

During mopping, the robot continues to spray clean water and immediately scrapes dirty water into the tank, so that the stain does not spread to other areas. The mop roller can also slide to the side to evenly clean the edges of the floor.

However, the biggest attention is directed at the Saros Rover, a prototype that gives an idea of the future of household robots. Unlike conventional vacuum robots, the Rover has a leg-like structure that can be raised and lowered independently, while still moving on wheels. In the demonstration, the Rover was able to maintain balance on uneven surfaces and, most ambitiously, it is claimed to be able to climb and clean stairs.

Even though it is not ready to be marketed, the Saros Rover marks what has been considered the "last frontier" for autonomous vacuum robots. If this technology matures, the concept of a multi-storey house without a broom and manual vacuum is no longer a marketing fiction.

Beyond floor cleaning, Roborock is also showing expansion into other areas. The company introduced the F25 ACE Pro, a wet-dry floor cleaning device that uses foam to tackle stubborn stains. For outdoor areas, the RockMow X1 line of lawn mowing robots is equipped with LiDAR and 4G tracking, and is capable of working on slopes with slopes of up to 80 percent.

The Roborock exhibition at CES 2026 confirms one thing: the evolution of robot vacuums is no longer about how powerful they are at sucking up dust, but rather how smart they are at moving around in real, messy, multi-level homes. If competitors follow this direction, human housework could really go into early retirement.
