Robot vacuums have spent years bumping politely into the base of staircases, forever exiled to a home’s ground floor. Dreame is trying to end that limitation with a machine that does not just roll, but actually lifts itself on mechanical legs to climb full steps and other obstacles. The result is a prototype that looks part appliance, part sci‑fi creature, and it signals how aggressively the Chinese brand is chasing the next phase of smart cleaning.
Instead of treating stairs as a cliff edge, Dreame’s latest concept treats them as just another surface to traverse, using articulated hardware and software that borrows more from robotics labs than from traditional vacuums. I see that shift as more than a party trick, because it connects directly to how multi‑story homes work in reality, and to a broader race among appliance makers to turn floor care into a fully autonomous system rather than a gadget that still needs to be carried between levels.
From flat floors to full stairs
Dreame’s new concept, called The Cyber X, is built around the idea that a robot cleaner should not stop at the first step. The company has equipped it with slightly unnerving legs that extend from the body and let the device haul itself up and down standard household stairs, rather than just nudging against them and turning away. In demonstrations, The Cyber X has been shown maneuvering up steps as tall as 25 centimeters, a height that covers most residential staircases and signals that this is not just about tiny thresholds but about full vertical transitions between floors, something earlier robots simply could not handle on their own.
Those legs are not just for show, and they are not limited to a single hop over a lip or rug edge. The Cyber X is designed to walk step by step, lifting its body and redistributing weight as it climbs, which is why some observers have described the motion as slightly terrifying compared with the gentle glide of a typical disc‑shaped robot. According to detailed coverage of the prototype, The Cyber X can maneuver steps up to 25 cm tall, which is the core technical claim that turns this from a marketing flourish into a meaningful change in what a home robot can physically do.
A prototype that treats the whole house as one map
What makes this machine more than a CES curiosity is the way Dreame is positioning it as a whole‑home navigator rather than a single‑floor specialist. The company has described the Cyber X as a prototype built to show how a robot could move through multi‑story environments autonomously, treating stairs as just another part of the route instead of a dead end. That approach depends on both the mechanical legs and a mapping system that can recognize where one floor ends and another begins, then plan a path that includes the staircase as a link rather than a hazard.
In practical terms, that means the robot has to understand not only the geometry of each step but also how to keep its center of gravity stable while it climbs, and how to resume cleaning once it reaches the next landing. Reporting on the prototype notes that the Chinese appliance maker Dreame has explicitly framed this as a research platform for navigating multi‑story environments autonomously, rather than a finished consumer product. That ambition is captured in coverage that describes how the Chinese appliance maker Dreame is using the Cyber X prototype to explore exactly this kind of whole‑home movement.
Safety systems for a robot that walks on edges
Once a robot starts walking on stairs, the stakes for safety rise sharply, both for the machine and for anyone walking nearby. Dreame has tried to address that by building a braking system into the Cyber X that can lock the robot in place on a step or landing, even if the battery dies mid‑climb. That is a very different risk profile from a flat‑floor vacuum that simply stops in the middle of a room when it runs out of power, and it shows how the company is thinking about edge cases like power loss or sensor glitches when the robot is perched above a drop.
The braking hardware is paired with software that keeps the robot’s posture stable as it transitions from horizontal floors to angled stair treads and back again. Coverage of the concept explains that the system is designed to keep the robot from sliding or tipping on stairs, and that the safety lock is meant to hold position even in a worst‑case scenario where the main systems shut down unexpectedly. That detail is highlighted in reporting that notes the Cyber X has a braking system that allows it to stay stable on floors and stairs, even if the battery dies, which is the kind of engineering safeguard that will matter if this concept ever reaches real homes.
From concept to product: Dreame’s stair‑climbing lineage
The Cyber X does not appear out of nowhere, and Dreame has been steadily building toward this kind of mobility with earlier products that flirted with leg‑like mechanisms. At CES, the company has used its booth to show off a progression of robots that can handle increasingly complex obstacles, starting with small step navigation and moving toward full staircases. One of the key milestones was a previous vacuum that could climb smaller steps and other obstacles, which set the stage for the more dramatic Cyber X demonstrations that followed.
That lineage is important because it shows Dreame is not treating stair climbing as a one‑off stunt, but as part of a broader roadmap for its cleaning lineup. Reporting on the company’s announcements notes that Dreame has also introduced the Dreame X60 Max Ultra alongside its more experimental concepts, tying the futuristic prototypes back to a family of high‑end consumer machines. The connection is clear in coverage that explains how Dreame announced the Dreame X60 Max Ultra in the same context as its stair‑climbing concept, signaling that the company sees a direct line from research prototypes to the premium products it is selling today.
Inside Dreame’s wider smart‑cleaning push
Stair‑climbing legs are only one piece of Dreame’s broader attempt to redefine what a home cleaning system can do. The company has been rolling out a full X60 Ultra series that leans heavily on automation, from self‑emptying docks to robotic arms that can pick up clutter before the vacuum starts its run. That strategy is about turning the robot into a more general household assistant, not just a floor sweeper, and it shows how Dreame is trying to differentiate itself in a crowded market of circular bots that all look and behave similarly.
One of the more striking examples is the Cyber10 Ultra, which is described as having autonomous tool‑utility technology with a multi‑joint robotic arm capable of picking up objects up to a specified weight before cleaning. That kind of hardware moves the product closer to a mobile manipulator than a simple vacuum, and it fits neatly alongside the Cyber X’s focus on advanced mobility. The company has framed these as industry‑first innovations within its X60 Ultra series, and that positioning is spelled out in material that describes how Cyber10 Ultra Features autonomous tool‑utility technology as part of a push to redefine smart cleaning.
ProLeap legs: from thresholds to “kind of” climbing
Before Dreame tried to walk a robot up full stairs, it experimented with smaller, more controlled forms of legged motion. The Dreame X50 Ultra Complete, launched at CES as a flagship robot vacuum, introduced retractable mechanical legs that could lift the body over door tracks and similar obstacles. Dreame branded this hardware and software package as its ProLeap System, and the idea was to let a wheeled robot temporarily step up when it encountered a lip that would normally stop it, then retract the legs and roll on as usual.
That ProLeap approach was a clear precursor to the Cyber X, and it showed both the promise and the limits of early legged designs. Reviews of the X50 Ultra Complete noted that the legs were impressive for crossing thresholds and small steps, but that marketing claims about stair climbing were, in practice, more modest than the slogans suggested. One detailed look at the product pointed out that the Dreame X50 Ultra robot was pitched as a stair climber, but that its actual capability was closer to navigating low steps and obstacles, a gap captured in coverage that described how the claim feels a bit overblown when compared with what most robot vacuums on the market can actually do.
How Dreame’s legged robots actually move
To understand what has changed between those earlier products and the Cyber X, it helps to look closely at how Dreame’s leg mechanisms work. The company has described the appendage on its X50 Ultra as a motorized swing arm that enables step navigation up to 6 centimeters in height, which is enough for many door thresholds and some raised transitions between rooms. That arm extends when the robot detects an obstacle of the right size, lifts the front of the chassis, and lets the wheels climb over before retracting so the machine can resume its normal low‑profile shape.
That design is still fundamentally a wheeled robot with a temporary assist, rather than a fully legged walker, and it is priced accordingly as a high‑end consumer vacuum. The Dreame X50 Ultra robot was introduced with a premium price tag and a launch window that positioned it as a flagship for the brand’s new mobility tech, and it is that same ProLeap lineage that now underpins the more ambitious Cyber X concept. The technical description of the earlier model notes that the Dreame X50 Ultra robot uses a motorized swing arm for step navigation up to 6 cm, which sets a clear baseline for how far the company has to go to reach the full‑stair performance it is now demonstrating with the Cyber X.
From design labs to living rooms
While the Cyber X is still a prototype, Dreame has already pushed some of its legged ideas into products that people can actually buy. The Dreame L50 Ultra, for example, is a robot vacuum and mop combo that uses a ProLeap system with retractable legs to climb door thresholds and similar obstacles in real homes. That model is less about dramatic stair ascents and more about solving everyday annoyances like getting stuck on the strip between a hallway and a carpeted bedroom, but it shows how the company is commercializing the same core concept in a more conservative form.
Independent testing of The Dreame L50 Ultra has highlighted its strong suction and cleaning performance, while also calling out the ProLeap legs as a distinctive feature that helps it cross transitions that would trap many rivals. Reviewers have noted that the legs deploy automatically when the robot senses a barrier, then tuck away to keep the profile low under furniture. One detailed review of The Dreame L50 Ultra describes how the Ultra model’s retractable legs enable it to climb thresholds and small steps, reinforcing the idea that Dreame is already selling leg‑equipped robots even as it experiments with more extreme prototypes like the Cyber X.
Retail reality: what shoppers can actually buy
For anyone curious about how these ideas translate into retail listings, the Dreame X50 Ultra and its relatives are already visible on major shopping platforms. Product pages describe how the X50 Ultra uses robotic retractable legs to cross thresholds, door tracks, and other obstacles that would normally block a standard robot vacuum. Those listings emphasize the ability to conquer door tracks and more, framing the ProLeap hardware as a way to keep cleaning runs smooth even in homes with uneven flooring or raised transitions between rooms.
The marketing language on these pages makes it clear that Dreame sees legged motion as a selling point, not just a technical curiosity. One listing for the DREAME X50 Ultra Robot Vacuum and Mop highlights that the robot can Cross Thresholds and Barriers using its retractable legs, promising to handle door tracks and thresholds without a hitch. That kind of phrasing shows how the company is already training consumers to think of legged robots as a practical upgrade, even if full stair climbing remains, for now, the domain of prototypes and high‑end demonstrations.
How Dreame explains its own robot evolution
Dreame’s own materials frame this evolution as a response to a simple problem: traditional robot vacuums get stuck too easily. The company’s blog explains that to keep a robot vacuum from getting hung up on things like the strips between rooms or the edges of thick rugs, it needs a way to lift itself over those obstacles without human help. That is the logic behind the ProLeap System, which Dreame presents as a way to let a wheeled robot temporarily change its geometry to step over trouble spots and then return to its low‑slung form for normal cleaning.
In that narrative, the Cyber X is not a wild departure but an extension of the same idea to more extreme terrain. The company points to the Dreame X50 Ultra as a concrete example of how this approach already works in shipping products, and then uses the Cyber X to show where it might go next if full staircases are treated as just another obstacle. That framing is laid out in a blog entry that notes how to keep it (your robot vacuum) from getting stuck, the Dreame X50 Ultra uses the ProLeap System, which is the same design philosophy now being pushed to its limits in the Cyber X’s full‑stair demonstrations.
Why legged vacuums matter for the next wave of home robots
For all the spectacle of a robot walking up a staircase, the underlying stakes are straightforward. If a cleaning robot can move between floors on its own, it can finally deliver on the promise of whole‑home autonomy without relying on humans to carry it or on duplicate units for each level. That is especially relevant in markets where multi‑story homes and townhouses are common, and where a single robot that can handle everything from the basement to the attic would be far more compelling than a fleet of floor‑bound discs.
At the same time, the Cyber X and its relatives highlight the trade‑offs that come with adding legs to an appliance that used to be simple and sealed. More moving parts mean more potential points of failure, and the slightly uncanny motion of a legged vacuum may not appeal to everyone. Yet as robotic vacuums get smarter and more capable, the line between appliance and robot is inevitably blurring, and Dreame’s work on machines that can Scale Obstacles like a New Robot Vacuum Has Legs suggests that climbing, stepping, and even manipulating objects may soon be as much a part of home cleaning as suction power and battery life.
A crowded field of Dreame robots
Beyond the headline‑grabbing prototypes and flagships, Dreame’s catalog now spans a range of robot vacuums that share design DNA with the Cyber X. Shoppers can find models like the Dreame Robot Vacuum X50 Ultra Complete White, the Dreame GoVac 600 Robot Vacuum and Mop, and the Dreame L50 Ultra Robot Vacuum listed across major search and shopping portals. These entries show how the company is segmenting its lineup, from more affordable mopping hybrids to premium Ultra models that inherit features like advanced navigation and, in some cases, retractable legs.
Those listings are not just marketing fluff, they are a snapshot of how quickly Dreame is turning experimental ideas into a family of products. Search results for the Dreame Robot Vacuum X50 Ultra Complete White, the Dreame GoVac 600 Robot Vacuum and Mop, and the Dreame L50 Ultra Robot Vacuum all point to a brand that is rapidly populating every price tier with variations on its core technology, while additional product search entries for the X50 Ultra Complete, the GoVac 600, and the L50 Ultra reinforce just how many variations of Dreame’s robots are already in circulation.
What early demos reveal about the Cyber X
Public demonstrations of the Cyber X have been limited, but the footage that is available offers a glimpse of how the robot behaves in the real world. In hands‑on videos from trade shows, the machine can be seen approaching a staircase, pausing briefly as its sensors map the steps, then extending its legs to begin a careful, deliberate climb. The motion is slower than a human’s and more mechanical, but it is unmistakably a walk rather than a roll, with the body lifting and settling on each step before moving to the next.
Those demos also show how the robot transitions back to wheeled motion once it reaches a landing, retracting its legs and resuming a more familiar glide across flat floors. Observers have noted that the process is still clearly a prototype, with exposed mechanisms and a cautious gait, but the core capability is there. One hands‑on look at Dreame’s booth captures this behavior in detail, with a Cyber X Stair‑Climbing sequence that illustrates both the promise and the current rough edges of a robot vacuum that has, quite literally, grown legs.
Where Dreame’s stair‑climbing experiment goes next
For now, Dreame’s full‑stair robot remains an experiment, but it is one that fits neatly into a broader pattern of increasingly capable home robots. The company has already shown that it can take ideas like the ProLeap System from concept to shipping product, and it is layering those mobility upgrades on top of a growing ecosystem of docks, arms, and software that aim to make cleaning as hands‑off as possible. The Cyber X is the most dramatic expression of that vision, turning a once‑static appliance into something that can traverse an entire house without human help.
Whether consumers are ready for a vacuum that walks like a small robot animal is still an open question, and Dreame will have to prove that the added complexity is worth the benefits in everyday use. Yet as legged prototypes climb full stairs at trade shows and Ultra‑branded models quietly step over thresholds in real homes, the direction of travel is clear. Dreame is betting that the future of floor care belongs to machines that can move through our spaces with far more freedom, and the Cyber X’s ability to climb full‑size stairs is the clearest sign yet that the age of truly mobile home robots is starting to take shape.
