As CES 2026 nears its end, the exhibition has featured a wealth of new devices and futuristic concept products. Leading robot vacuum manufacturer Roborock unveiled the Roborock Saros Rover, the world's first robot vacuum capable of climbing stairs and performing cleaning, at this event. As soon as it appeared, it elicited exclamations of amazement from a group of tech enthusiasts. It is just like a consumerized civilian version of the Two-wheeled Balancing Infantry from RoboMaster competitions, full of technological appeal.

Roborock Saros Rover, Dreame Cyber X, and the Evolution of Stair-Climbing Robots
This Roborock Saros Rover adopts a leg-style structure with two wheeled legs. The two wheels can maintain front-to-back balance, allowing stable advancement on stair slopes while simultaneously cleaning the stair treads. This perfectly solves a new pain point for multi-floor residences that even equipping each floor with a robot vacuum cannot address—the inability to clean stair treads.
In official demonstration videos, we can see the Saros Rover performing small jumps to overcome laser obstacles, as well as maintaining balance when struck by tennis balls. This demonstrates its capability to handle complex terrain and its stability.

However, this technology is currently still in development and not yet mass-produced. Many netizens have some concerns about its stability, after all, in actual cleaning work, the robot vacuum needs to maintain balance with varying amounts of water in its onboard water tank, and once a mistake occurs during stair climbing, it could be comparable to a disaster scene. After all, videos of it tipping over have already emerged from the CES site. Moreover, from on-site videos, its stair-climbing speed is still relatively slow. Netizens question whether allowing it to clean a multi-floor residence would inevitably take a very long time.
Another problem that needs to be solved is that once robot vacuums begin cleaning multi-floor residences, their battery capacity and efficiency also need significant improvements. Otherwise, it would be difficult for the robot vacuum to have sufficient power to clean the floor surfaces after climbing the stairs. This model is currently in development, with no confirmed release date. We look forward to the engineering team resolving these concerning issues and creating a product that amazes consumers.
Emerging Trends: Dreame's Innovations in Obstacle and Stair Navigation
techTongBo, as a factory specializing in robot vacuum accessories, continuously keeps an eye on the latest developments in the robot vacuum industry. The design trend of enabling robot vacuums to cross obstacles, or even climb stairs, already showed early signs last year. The Dreame X50 Ultra adopted the ProLeap System. This intelligent system uses small electric retractable legs to lift the vacuum body, easily overcoming obstacles.

Not long ago, in December of last year at IFA in Berlin, major brands attempted to address the issue of robot vacuums climbing stairs. Dreame had already launched the bionic quadruped tracked stair-climbing robot vacuum Cyber X. It is the first consumer-grade robot vacuum capable of successfully climbing stairs. But the regrettable point is that this vacuum can only climb stairs and cannot clean the stair treads. It adopts a tracked base that is separate from the robot vacuum; during cleaning, the vacuum needs to detach from the base. Its stair-climbing speed is much faster than the Roborock Saros Rover.

From appearance, the Dreame Cyber X seems much bulkier than the Roborock Saros Rover. Many netizens have expressed concerns about whether prolonged use of such tracks would cause wear and potentially scratch the edges of stair treads. At the same time, for multi-floor residences, one stair-climbing robot vacuum would be quite expensive, and equipping each floor with a robot vacuum would not cost much more while providing higher cleaning efficiency. Such a stair-climbing function then appears somewhat redundant.
Looking Ahead: The Rapid Growth of Smart Home Cleaning with Stair-Climbing Robots
The demand for intelligent home cleaning is growing rapidly. Perhaps no one expected that the robot closest to people's fantasies of a helpful robot assistant—and the quickest to enter millions of households—would actually be the robot vacuum. The next step is to hope that this technology allowing robot vacuums, such as the Roborock Saros Rover and Dreame Cyber X stair-climbing robots, to climb stairs and clean stair treads develops steadily, improving accessory durability, until mass production, letting technology truly liberate our hands.
techTongBo (also named: Nanjing TongBo / NJTB) is a Chinese company specializing in the manufacture and sales of vacuum cleaner accessories. We offer replacement accessories for the global market that are compatible with mainstream vacuum cleaner brands and have stronger price advantages.
