What Is the Marswalker?

Eufy presented a new accessory called the Marswalker, a rugged, tracked platform designed to move robot vacuums across stairways. The device resembles a small rover with four independently controlled arms that grip each step as it climbs. It can recognize straight, L‑shaped and U‑shaped stairs, building a three‑dimensional map of the home to navigate autonomously. The Marswalker does not clean the stairs themselves; instead, it transports a compatible vacuum to a different floor and returns to its dock for charging and emptying.
