2026 verdict
A robot that mops beats one that doesn't, most of the time, and that's exactly how this matchup plays out: the eufy Omni S2 wins overall on rating, battery life, obstacle detection, mopping and self-emptying. It vacuums and mops in one pass with a dock that washes and hot-air dries the mop pad automatically, runs 150 minutes per charge, and adds obstacle detection the Roomba 205 doesn't document. The iRobot Roomba 205 answers with a real, distinctive edge of its own: an internal DustCompactor that presses debris down inside the robot itself instead of relying on a bulky auto-empty tower, plus cliff detection, no-go zones, IFTTT support and a much lower price. It's vacuum-only, with no mopping, detergent compatibility or auto mop features at all. Buyers who want vacuuming and mopping handled together with a self-cleaning dock should choose the eufy Omni S2, while those who want a compact, dock-free, budget-friendly vacuum for pet hair on a single floor should pick the iRobot Roomba 205.
