Overview

• Eufy demonstrated Marswalker in Berlin with a video showing the system moving up and down stairs using a separate tracked ferry with support arms.
• Marswalker separates transport from cleaning, allowing the vacuum to disembark and operate normally on each floor before returning to its base.
• The company says navigation sensors recognize various stair shapes and build a 3D map of the home, enabling multi-floor automation.
• Eufy does not plan a market launch before 2026, and pricing for Marswalker has not been announced.
• Heise reports other makers are exploring similar ferry-based approaches after integrated designs like Migo Robotics’ Ascender collapsed in 2024.
