Robot vacuum companies are once again out in full force at CES 2026, giving their devices a new set of intriguing \u2014 and sometimes unsettling \u2014 capabilities. This year, Chinese appliance maker Dreame is showing off a vacuum prototype with giant legs that can climb up and down an entire flight of stairs.<\/p>\n
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<\/a>, 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.<\/p>\n We got a chance to see the Cyber X and its stair-climbing abilities at Dreame\u2019s CES booth, and the device was able to deftly crawl up and down a flight of stairs. The Cyber X didn\u2019t use its \u201clegs\u201d to walk up the steps, though. Instead, it used the treads horizontally, moving a bit like a miniature, cleaning tank.<\/p>\n Interestingly, the actual vacuum is separate from the climbing apparatus. As you can see in the image below, the larger device with legs has an opening where the actual robot vacuum can dock inside and sit while the Cyber X climbs stairs.<\/p>\n That likely means the Cyber X isn\u2019t able to clean the stairs themselves, though it does cleverly solve the problem of transporting the vacuum throughout multi-story environments.<\/p>\n In addition to its legs, the Cyber X\u2019s vacuum 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.<\/p>\n![\"Dreame's](\"https:\/\/s.yimg.com\/ny\/api\/res\/1.2\/89GEkLFqdJlnVTG5FLMkHw--\/YXBwaWQ9aGlnaGxhbmRlcjt3PTk2MDtoPTU0MA--\/https:\/\/d29szjachogqwa.cloudfront.net\/images\/user-uploaded\/dreame_cyber_x_and_base.jpg\"\/)
