Overview

• The MarsWalker uses four independently controlled arms and a track‑drive system to carry a docked vacuum between floors while gripping steps securely.
• On‑board 3D mapping helps it navigate straight, L‑shaped, and U‑shaped staircases and coordinate handoffs so the vacuum can resume cleaning or return to its base.
• Compatibility is limited to select Eufy models with no support for third‑party robot vacuums.
• Eufy plans a launch in spring or the first half of 2026 and has not announced a price.
• A confirmed compatible model, the RoboVac Omni S2, is slated for the U.S. in January 2026 at $1,599 with 30,000Pa suction, a self‑cleaning roller mop, mop lift, improved obstacle avoidance, and a built‑in fragrance system.
