Multi-story homes have always been the nemesis of robot vacuums. You finish cleaning downstairs, then face the reality of manually hauling your expensive Roomba upstairs like some kind of robotic sherpa. Eufy’s MarsWalker eliminates that tedious routine entirely—this autonomous transport platform carries your vacuum between floors without any human intervention. The device represents a genuine breakthrough in making whole-home automation truly hands-off for multi-level households.
Think of MarsWalker as a Mars rover for your hallway. Four independently controlled robotic arms grip and maneuver a compatible vacuum while track-drive systems navigate straight, L-shaped, or U-shaped staircases. This isn’t a vacuum with climbing abilities bolted on—it’s a purpose-built carrier that separates transport from cleaning, keeping both functions optimized for their specific tasks.
The automation workflow feels like science fiction made practical. When your Eufy Omni S2 completes a floor’s cleaning cycle, it autonomously docks with the waiting MarsWalker. The platform then climbs to the next floor, releases the vacuum to resume its routine, and eventually returns it to the base station for recharging or maintenance. No apps to trigger, no schedules to coordinate—just seamless whole-home automation that actually lives up to the smart home promise.
MarsWalker’s navigation relies on cameras and sensors creating 3D home maps, detecting stair geometry and planning safe climbing routes. The demonstration at IFA 2025 showed reliable performance across various staircase types, suggesting this isn’t just trade show theater but functional consumer technology ready for real-world deployment.
Reality check: MarsWalker doesn’t clean stairs themselves—dirt accumulating on steps still requires manual attention or separate tools. Launch compatibility is limited to select Eufy models, starting with the Omni S2, so third-party vacuum owners are excluded from this particular robot revolution. You’ll still need that manual stair cleaning routine, just not the vacuum-carrying part.
Scheduled for first-half 2026 availability, MarsWalker enters a competitive field alongside Dreame’s CyberX and MOVA’s Zeus 60 modules. Pricing remains undisclosed, but adding a robotic stair climber to an already premium vacuum system might approach the cost of simply buying two separate units for different floors. When that pricing drops, you’ll need to weigh total automation convenience against the simple reality of occasionally carrying things upstairs yourself—though for households with mobility challenges or sheer commitment to robotic convenience, MarsWalker could justify its premium positioning.
