Overview

The Omni S2 is eufy's 2026 flagship, a low 96 mm robot with no lidar dome that maps with a camera and time-of-flight sensors and mops with a self-rinsing roller. Its dock washes the roller with hot water, dries it with hot air and can be plumbed in with an optional kit. Vacuum Wars found it stronger than the S1 Pro on carpet and pet hair, but its mopping trails the S1 Pro and its navigation is slow. The launch slipped from January into spring 2026 after early units were pulled from sale (unconfirmed). It is the first robot built to ride eufy's MarsWalker, a tracked carrier that climbs stairs and moves the robot between floors, which was announced at IFA 2025 for spring 2026 but was not listed on eufy's store in October 2026. Cheaper siblings include the Omni E25/E28 and X10 Pro Omni.
