Pros & cons
Roborock Saros 20
- ✓AdaptiLift 3.0 chassis climbs double-layer thresholds up to 3.46 inches - unmatched for split-level homes
- ✓36,000Pa suction and a 6,400mAh battery cover large homes with up to 200 minutes of runtime
- ✓Embedded 3D ToF StarSight 2.0 LiDAR keeps the body at 3.1 inches to slide under low furniture
- ✓Dual spinning mops apply adaptive pressure up to 13N and get washed in 212°F hot water at the dock
- ✓Recognizes around 300 obstacle types with VertiBeam lateral avoidance for cables and clutter
- ✗At $1,599.99 it costs flagship money without the Sonic's vibrating deep-scrub mop
- ✗Small 69ml onboard water tank means constant dock returns on big mopping jobs
- ✗259ml dustbin is modest for a vacuum aimed at large, complex homes
- ✗Tall multifunction dock demands a lot of floor and vertical clearance
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
