Stairs are one of the last big challenges to be overcome by robot vacuums. Cleaning performance is getting better with each new model, for both vacuuming and mopping, and robots are better able to navigate spaces and obstacles. But until now, none have been able to climb stairs. That’s set to change with Eufy’s Marswalkers and Dreame’s new Cyber X concept, which our sister site PCMag was able to see in action at IFA, the tech show in Berlin. “Eufy’s version resembles a space rover, while the Dreame concept looks more like a construction vehicle,” wrote Andrew Gebhart, PCMag’s senior writer for smart home and wearables. “It has large treads in each corner that start horizontally to roll the vacuum forward and get it into position at the base of a staircase. Then, the front treads turn vertical to feel up and over the first step and get a gauge of the height. At that point, they pivot and lift the whole contraption to an angle before the treads turn back to a horizontal position, and the Cyber X moves rather fluidly up the stairs.” On paper, this sounds awfully similar to the Marswalker, though it seems like the Cyber X may also work similarly, acting as an autonomous shell that allows other bots to hitch a ride. In any case, the Cyber X is still a concept and there isn’t any indication of when or if it’ll actually go on sale and what robot vacuums will be compatible. The Eufy Marswalker, on the other hand, is anticipated for 2026 and is confirmed to work with the Omni S2. Dreame Cyber10 Ultra On the more concrete side, Dreame is also taking its shot at arm-equipped robot vacuums, with the new Cyber10 Ultra, serving as its answer to the arm-equipped Roborock Saros Z70. The mechanical arm allows robots to not just clean and mop your home but also pick up items, sort socks and generally help you clean up clutter. This sounds great in theory, but in practice, the actual implementation is hit and miss. Our testing of the costly Roborock Saros Z70 revealed that it often was unable to complete sorting tasks or couldn’t recognize objects like cat toys, though it did improve over time with software updates. PCMag's Gebhart watched the Cyber10 Ultra pick up and move a sock. Andrew Gebhart/PCMag Gebhart also got a look at the Cyber 10 Ultra, watching it pick up a sock and bring it to a basket in the corner. He noted that its arm is stronger, being able to handle objects of 17 ounces, compared with the Saros Z70, which topped out around 10 ounces. Pricing for the new robot isn’t known yet, but Dreame expects to launch it in early 2026.
