Stairs are the enemy of robot vacuums everywhere. There isn’t currently a single robot vacuum on the market that can climb a flight of stairs without human assistance. Even the best robot vacuums we recommend for their ability to cross obstacles, like the Dreame X50 Ultra and Roborock Saros Z70, can only handle thresholds between two and three inches.
Eufy’s Marswalker may be the first robot vacuum to truly be able to tackle this problem. It’s a robot vacuum that looks a bit like a wheeled Mars rover with a tracked drive, the “smart crawler platform,” that allows it to ascend and descend staircases. Eufy demonstrated the feature for me in a video, and describes the platform as “four independently controlled arms” with a track-drive system that grips each step as it climbs. It’ll also be at Eufy’s IFA booth in Berlin for a live demo.
In the meantime, here's what we know about it.

Now, the Marswalker doesn’t clean the staircase itself while climbing, but it can get to a different floor without human assistance, which is huge. Eufy says the Marswalker is fully autonomous and will automatically detect when one floor is finished being cleaned and will climb to the next one without human intervention.

Eufy says the robot will automatically recognize common stair types, including straight, L-shaped and U-shaped stairs, as it builds a 3D map of the entire home. After traveling up a flight of stairs for cleaning, the Marswalker can automatically return to its dock to empty and recharge.

While details are scarce, from the pictures, it appears that the Marswalker is a shell that fits over an existing robot vacuum, rather than a standalone robot. Eufy notes that the Marswalker is compatible with its new Omni S2 robot vacuum, which the company claims is the first with an intelligent aromatherapy system, releasing fragrances like bamboo, sage, bergamot, lychee, citrus and basil as it cleans your home.
