eufy Omni S2 vs Roborock Saros 20 Flow

What owners say

Owners of the eufy Omni S2 are most enthusiastic about the mop, saying the roller lifts ingrained mud and sticky patches that pad mops leave behind and switches between hard floors and rugs without fuss. Suction draws the second round of praise, and one owner who compared it directly with a rival flagship notes the bin keeps airflow up after a week of nightly runs rather than caking the filter. Obstacle avoidance marks shoes, cords and even a paper plate on the map and steers around them, and owners also cite a premium build, quiet cleaning outside the self-empty cycle, and a tall dock that makes the tanks easy to fill. The criticism is software and reliability: some robots get lost on complex layouts, the Android app is called buggy, map edits do not stick, and a handful of units threw repeated errors.
