- Eufy and Dreame have announced the climbing robot vacuum cleaners in Ifa
- The Eufy Marswalker and Dreame Cyber X use independent arms and rollers to climb steps
- Eufy’s will go on sale ‘next year’, but Dreame is in the conceptual stage
You wait years for a void robot that can climb stairs, and then two appear at the same time. There are many new great robovacs that debut in Ifa, but none as exciting as Dreame Cyber X and Eufy Marswalker.
One of the biggest problems with robots vacuum cleaners is their inability to move without assistance between floors. Even today’s best robot vacuum cleaners can only clean a story of their home at the same time, which puts a significant limit on how truly autonomous it can be. Of course, you can carry your bot between floors, but once it is made, you will need to take it back to load (and perhaps also empty your container and clean your MOP pads), which means that it must be presented during the entire cleaning process.
However, all that could be about to change, with two main robovac brands, both revealing bots that can cross full flights of steps: the Euphy Marswalker and Dreame Cyber X. I have seen so much in action in IFA 2025, and for me, there is a clear winner.
As for the design, the concepts are very similar. Both have four arms that move independently that turn to hit the robovac in the first step, and then the roller tracks that guide it down (or up) of the flight in a controlled way. In both cases, the arms are not attached to the robot itself, but they are part of a separate module in which the embedding robot.
This acts as a small robovac transport pocket to bring the stairs and deposit it on its new floor (both brands say that their bots can identify the type of staircase, which go directly, those that turn a corner halfway, and so on). Then he will leave the pocket to do the cleanliness.
At first he disappointed me that the arms were not in the robot itself. In that sense, it is not In fact A staircase of robovac climb. However, the benefit here is that the climbing module could match a range of different bots, instead of being tied to one.
As for the design, the biggest difference is that the clues in the EuFy Marswalker are right in the main part of the climbing module, while in The Dreame Cyber X they also run along the full length of the arms. The benefit of the DREame approach is that it could be a little safer.
However, after having seen both in action, Eufy’s is the bot that I would choose. He climbed the stairs more softly and more confidently, and went up / down to the first step much faster too. (The Dreame model approached this initial challenge at the speed of a geriatric turtle).
In general, the Euphy model seemed much more complete than dreame, at least, based on what I saw. Eufy had his own cargo spring for the staircase module, which was maneuved again in one that had left the bot. They also told me that this bot will go on sale ‘next year’.
In contrast, the effort of dreams is still in the conceptual stage. Without signs of a cargo spring and we had to wait ~ 10 minutes to ‘rest’ before he could embark on any race.
You can see the euphy in action below, but be careful that there are some very unpleasant Stroboscopic lighting in this video.
During the past year, we have been seeing more and more bots that can run into especially high room thresholds (perhaps the most notable example is the ultra -complete dreame x50 with their small feet, but many brands have been exploring this problem). However, this represents something quite different, and if it works reliably, it will be a great advance in robot vacuum technology.
