Pros & cons
Eufy Omni S1 Pro
- ✓Roller mop is washed and squeegeed in real time — it never drags dirty water across the floor
- ✓Reddit owners call the mopping the best in class: lifts 48-hour dried stains without streaks
- ✓Sleek 3.78-inch body slides under furniture that blocks turret robots
- ✓Ozone-treated water sanitizes without detergent smells
- ✓2-year Anker warranty with responsive US support
- ✗8000Pa suction and 250ml bin make it a mopping-first machine — carpet homes should look elsewhere
- ✗Dirty water tank is built into the dock and awkward to carry to a sink
- ✗No Matter or advanced smart home integration yet
- ✗Launch price was $1499 and it still sells above most spinning-pad rivals
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
- ✗Premium $1,599.99 price with slower, less efficient navigation than other flagships
- ✗Threshold climbing is inconsistent on taller 1.25-inch (32mm) transitions
- ✗Camera/ToF navigation skips the LiDAR turret, so mapping can struggle in very dark rooms
