Eufy announces new S2 robot vacuum with stair-climbing accessory

Anker has announced the eufy Robot Vacuum Omni S2. The company claims that it is the first model of its kind, combining the CleanMind AI system, AeroTurbo vacuum and HydroJet mopping providing deep cleaning.

The Robot Vacuum Omni S2’s AeroTurbo 2.0 technology with 100 AW power delivers up to 30,000 Pa suction. This is said to make it suitable for carpets up to 5 cm (~2.0 inches) deep. Underneath the robot are DuoSpiral detangle brushes, and the extending side-arm helps the robot to clean along the walls. The HydroJet 2.0 system includes a roller mop that rotates 360 times per minute and applies 15N downward force. The mop can extend up to 15 mm (~0.6 inches), and the robot has tanks for both clean and dirty water to keep your floors as clean as possible. Plus, after cleaning, the robot can wipe your floors with an optional scent: citrus basil, bamboo sage or bergamot lychee.

Eufy markets the Omni S2 as featuring its CleanMind AI system, a combination of 3D ToF, RGB camera and LED technologies. It can climb over obstacles up to 4.2 cm (~1.7 inches) tall, and recognises 200 types of obstacles. Plus, at the 12-in-1 UniClean docking station, the robot is automatically emptied, and the mop is washed with hot water and dried with hot air. Other features include app-based controls and support for the Matter standard.

At IFA 2025, Eufy is also demonstrating its new MarsWalker stair-climbing carrier for robot vacuums. Compatible with the S2, the device can transport the robot up and down straight, L-shaped and U-shaped stairs, so it can clean on multiple floors. The MarsWalker achieves this with a track-drive system and four independently controlled arms to push and pull it up or down each stair.

The eufy Robot Vacuum Omni S2 will launch in late October in Europe for £1,599.99/€1,599.99. It is expected to be released in the US in early 2026 for around $1,599. Meanwhile, the eufy MarsWalker accessory is currently scheduled for release in spring 2026, though its pricing remains uncertain.
