Pros & cons
Eufy Omni S2
- ✓Huge carpet upgrade over the Omni S1 Pro - 87% embedded sand removal versus the S1's 61% in Vacuum Wars testing
- ✓Perfect 24-of-24 obstacle avoidance run thanks to 3D MatrixEye ToF vision with an auto LED light matrix
- ✓HydroJet 2.0 roller mop continuously self-cleans with electrolyzed water through 32 injection holes and posted a 0% hair-tangle rate
- ✓DuoSpiral split main brush and extending side brush chew through long pet hair without wrapping
- ✓12-in-1 UniClean dock handles emptying, 140°F mop washing, 131°F drying, water refills, and three-scent aromatherapy
- ✗Hard-floor mopping actually scored worse than the cheaper Omni S1 Pro in head-to-head testing
