Narwal Flow 2 Robot Vacuum vs Eufy S2 Omni Robot Vacuum Mop

Both are flagship rolling-mop robots with self-cleaning docks and roughly 30,000 Pa suction, so the choice comes down to obstacle avoidance and mop heat versus tank capacity and carpet reach. The Narwal Flow 2 has dual cameras for millimeter-level dodging, a 212°F dock wash and a 140°F mop wash, and owners rate it 4.8 from 107 ratings, praising carpet suction, quiet running and the belt mop. The Eufy S2 counters with a 3L dust bag, larger clean and dirty water tanks, 15N mop pressure, 15mm mop extension into corners and a chassis that lifts for carpets up to 2 in thick. Pick the Narwal for cluttered pet homes that want the best obstacle reporting; pick the Eufy for bigger floors, thicker carpet and fewer dock trips.

• Choose the Narwal Flow 2 if you have pets, a cluttered floor and want the strongest obstacle avoidance and the hottest dock wash.
• Choose the Eufy S2 Omni if you have thick carpet, a large floor plan and want bigger tanks and a longer self-empty interval.
