Dreame's latest robot vacuum concept has slightly terrifying legs that can climb full-size stairs

Robot vacuum companies are once again trying to outdo each other at CES 2026. This year, Chinese appliance maker Dreame is showing off a prototype of a device that can climb up and down an entire flight of stairs.

The concept, called the Cyber X, was previewed last year at IFA in Berlin. The vacuum sports a somewhat terrifying set of legs with rubber treads that allow it to autonomously navigate multi-story environments. While Dreame has previously shown off vacuums that can move up smaller steps, it says the Cyber X can climb stairs up to 25cm (9.8 inches) high and slopes up to 42 degrees. It can manage both straight and curved staircases, and can climb a flight of steps in 27 seconds, according to the company.

In addition to its legs, the Cyber X also has a built-in water tank to support mopping abilities, and a laser-powered navigation system to help it maneuver up stairs and around other obstacles. It also has a braking system that allows it to stay stable on floors and stairs, even if the battery dies. We haven't been able to see it in action yet, but Dreame is expected to show off its abilities at its CES booth and we'll update this post once we're able to get an up-close look.

For now, Dreame says Cyber X is just a research prototype and hasn't indicated if it plans to make it, or a robo vac like it, more widely available at some point in the future. But Dreame has a history of showing off innovative features at CES ahead of an actual release. Last year, the company had a prototype vacuum with a mechanical arm at its CES booth. This year, it announced a new vacuum with very similar abilities. 

The company also announced the Dreame X60 Max Ultra, its latest flagship robot vacuum that can roll up smaller steps. The X60 Max Ultra, which costs $1,699, can move over stairs up to 8.8cm (about 3.4 inches), a small improvement over last year's X50, which could clear heights of 6cm (about 2.4 inches). That's not enough to manage a full-size stair, which is typically around 7 inches, but it should make the X60 flexible enough to navigate threshold steps and other small obstacles.
