Eufy's MarsWalker allows its robot vacuums to climb stairs

Eufy, a smart home device manufacturer, has introduced a new product called the MarsWalker, which allows its robot vacuums to climb stairs. The MarsWalker automatically recognizes different stair types and transports the vacuum between floors, dropping it off at the base station when needed. The device uses four control arms and a track-drive system to grip each step securely and prevent slips. While the MarsWalker is a promising innovation, there are some caveats. The pricing is not yet known, and it only works with a few Eufy models, not third-party devices. Additionally, the company has announced a new robot vacuum, the Omni S2, which fully integrates with the MarsWalker. The Omni S2 features an aromatherapy system and adaptive wheels to handle thick rugs, and will be available in January for $1,600. Overall, the MarsWalker represents a significant step forward in the capabilities of robot vacuums, allowing them to navigate multi-story homes more effectively. However, the limited compatibility and potential high cost may be drawbacks for some consumers.
