Stairs are enemies full of robot vacuums. Currently, there is no robot vacuum cleaner on the market that can climb up stairs without human assistance. Even The best robot vacuum cleaner We suggest them Dreame X50 Ultra and Roborock Saros Z70can only handle thresholds between two and three inches.
Eufy’s Marswalker may be the first robot vacuum cleaner to really solve this problem. It’s a robot vacuum that looks a bit like a wheel Mars rover with a tracking drive that takes it up and descends to the stairs. Eufy showed me this feature in the video and described the platform as “four independently controlled weapons” whose orbital drive system grabs every step as it climbs. It will also be presented live at the IFA booth in Eufy, Berlin.
At the same time, that’s what we know about it.
The Eufy Marswalker is a robot vacuum cleaner that can actually climb stairs on its own.

Now, Marswalker won’t clear the stairs itself while climbing, but without human aid it can reach another floor, which is huge. Marswalker is completely autonomous and will automatically detect when a layer is cleaned and will crawl to the next without human intervention, Eufy said.
Marswalker can work independently, reprocess the stairs and navigate without human intervention.
Eufy said the robot will automatically identify common stair types, including straight, L-shaped and U-shaped stairs, as it is built for 3D maps of the entire house. After cleaning up the stairs, Marswalker can automatically return to its dock to empty and charge.
Marswalker can handle different types of stairs, although it won’t clean the stairs themselves.
Despite the slightest detail, from the picture, the Marswalker is a shell suitable for existing robot vacuums rather than standalone robots. Eufy notes that Marswalker is compatible with its new Omni S2 robot vacuum, which the company claims is the first to have an intelligent aromatherapy system that releases bamboo, sage, bergamot, bergamot, lychee, lychee, lychee, citrus, citrus, citrus and basil and cleans the house.
In terms of specifications, Marswalker has the same 3D mapping and AI capabilities as the Omni S2. Other details, including pricing, are not available yet, but Marswalker should be released in spring 2026, which could make it the first real stair climbing robot vacuum on the market unless the competitor beats Eufy.
Marswalker is expected to be released in 2026, and the price is still unclear.
This is definitely one of the products I’m most excited about. Using robot vacuum cleaners in multi-layered houses is a huge pain. Many robot vacuum cleaners offer multi-stage mapping, but they do not provide solutions from one layer to another. You either carry the unit yourself or you have to buy a second unit and live on their respective floors. This is not a good solution either. If Marswalker could change that, it would most likely be the biggest innovation the robot vacuum market has seen in a long time, beating the mechanical division of the Roborock Saros Z70.
Eufy Robovac Omni S2
The Omni S2 has an all-in-one base station and an aromatherapy system that releases odors while cleaning.
The above-mentioned Omni S2 is Eufy’s latest and top robot vacuum cleaner. It comes with a 30,000 suction pascal (100 watts), is capable of vacuuming and mopping, and can apply 15 Newtons of downward pressure when the motorcycle is on. It has advanced navigation with 3D TOF sensor, RGB camera and LED lights. It can identify more than 200 obstacles and identify more than 40 dirt. It can also handle 4.2 cm obstacles with a double threshold and 3.5 cm obstacles with a single threshold, although it will not be able to climb stairs by itself.
It won’t climb stairs alone, but the Omni S2 can cross a threshold of up to 4 cm. It is also compatible with Marswalker.
Naturally, you will get a self-cleaning and auto-filling dock that can clean and disinfect uses and use fresh electrolytic water to clean the floor. All of this makes it a pretty effective robot vacuum cleaner, although I most want to know how it works with Marswalker.
The OMNI S2 is expected to be available in the U.S. starting in January 2026, with a price of $1,599.
