Who needs legs? Eufy, Anker’s smart home brand, believes it has solved the problem of how a single robot vacuum can clean multiple floors in your home. Its new MarsWalker robot is equipped with four arms to carry a vacuum between levels, so you don’t have to lug it up the stairs yourself or buy a robot for each floor. However, you’ve now got two robots, so perhaps it’s not really solving that problem.
Equipped with a drive-track system, the MarsWalker acts like a stairlift for your robot vacuum. The vacuum docks in the MarsWalker, which carries it to the next floor using four independently controlled arms. From there, the vacuum exits to resume cleaning or head to its base station to wash its mop, empty its bin, or recharge.
Eufy says the MarsWalker can tackle straight, L-shaped, and U-shaped stairs and builds a 3D map of your home to understand where the vacuum needs to go. It’s a standalone unit with its own charging base, and the company says it will work with several models of Eufy robot vacuums, although exact specs and compatibility haven’t been released. It’s slated to launch in the spring of 2026, but no pricing has been announced.
One compatible model will be the new Eufy RoboVac Omni S2, which is also on show at IFA. Due to launch in the US in January for $1,599, the S2 is an upgraded version of the Eufy S1 Pro.
The S2 features a large, self-cleaning roller mop, 30,000Pa suction power, 3.3lbs of downward mopping pressure, and can extend its mop out up to 15mm to clean along baseboards. It has a new DuoSpiral brush to prevent tangling, while improved obstacle detection enables the vacuum to avoid rug tassels as well as over 200 other objects. It can also elevate its mop up to 2 inches to avoid getting carpets wet.
It also features a built-in fragrance system that releases various scents while cleaning, including citrus, basil, bergamot, and lychee. The futuristic cleaning station automatically empties the bin, washes and dries the mop, and refills the onboard water tank.
I’ll be getting a look at the new MarsWalker this week at IFA and will report back with first impressions.
