## Pros

- Deep cleans carpet far better than the Omni S1 did (Vacuum Wars, https://vacuumwars.com/eufy-s2-review/)
- Avoided every obstacle in both its standard and harder tests (Vacuum Wars, https://vacuumwars.com/eufy-s2-review/)
- Long hair does not wrap around its split main brush (Vacuum Wars, https://vacuumwars.com/eufy-s2-review/)
- Vacuums and mops equally well, which few robots manage (TechRadar, https://www.techradar.com/home/robot-vacuums/eufy-omni-s2-review)
- Bin, brushes and mop still looked new after weeks of daily use (TechRadar, https://www.techradar.com/home/robot-vacuums/eufy-omni-s2-review)
- Crosses raised rugs and door thresholds that stumped the older S1 (TechRadar, https://www.techradar.com/home/robot-vacuums/eufy-omni-s2-review)
- Strong suction lifts plenty of dust and debris from carpet and hardwood (Tom's Guide, https://www.tomsguide.com/home/smart-home/i-tested-the-eufy-omni-s2-and-it-excels-in-just-about-everything-except-this-one-thing)
- Mops without streaks and wipes up sauce without smearing it around (Tom's Guide, https://www.tomsguide.com/home/smart-home/i-tested-the-eufy-omni-s2-and-it-excels-in-just-about-everything-except-this-one-thing)

## Cons

- Uses little water, which holds it back on dried-on stains (Vacuum Wars, https://vacuumwars.com/eufy-s2-review/)
- Gets over tall thresholds only some of the time (Vacuum Wars, https://vacuumwars.com/eufy-s2-review/)
- Covers floor slower than average, so it cleans less area per charge (Vacuum Wars, https://vacuumwars.com/eufy-s2-review/)
- The dirty water tank smells badly unless you empty it often (TechRadar, https://www.techradar.com/home/robot-vacuums/eufy-omni-s2-review)
- High running costs, with detergent and scent refills sold only by eufy (TechRadar, https://www.techradar.com/home/robot-vacuums/eufy-omni-s2-review)
- The first test unit lost its link with the dock and was replaced (TechRadar, https://www.techradar.com/home/robot-vacuums/eufy-omni-s2-review)
- Leaves uncleaned strips along edges and under overhanging cabinets (Tom's Guide, https://www.tomsguide.com/home/smart-home/i-tested-the-eufy-omni-s2-and-it-excels-in-just-about-everything-except-this-one-thing)
- Struggles in tight spaces and bumps its way back out (Tom's Guide, https://www.tomsguide.com/home/smart-home/i-tested-the-eufy-omni-s2-and-it-excels-in-just-about-everything-except-this-one-thing)
- Its airflow can blow clumps of pet hair around instead of collecting them (Tom's Guide, https://www.tomsguide.com/home/smart-home/i-tested-the-eufy-omni-s2-and-it-excels-in-just-about-everything-except-this-one-thing)
