Eufy Omni C28 vs eufy Omni S2

The eufy Omni S2 wins overall: it is better rated, runs 150 minutes against 140 and doubles the suction at 30,000Pa against 15,000Pa, with electrolyzed-water mopping and a five-layer allergen filter. The Eufy Omni C28 is cheaper and documents no-go zone support.

Suction and mop water. The eufy Omni S2 pulls 30,000Pa and makes electrolyzed water on the fly for certified germ removal, then hot-washes and hot-air dries. The Omni C28 uses a conventional HydroJet roller at 15,000Pa, which is still effective on hard floors.

The eufy Omni S2, which pairs multi-cone cyclonic separation with a five-layer allergen filter and a mop system certified for germ removal. The Eufy Omni C28 self-empties into a sealed 3L bag, which also limits dust exposure, but its filtration is simpler.

Yes. The Eufy Omni C28 is rated at roughly 55dB and the eufy Omni S2 at 59dB, so neither is disruptive in a normal home, though the S2 is working harder with far more suction when it makes that noise.

Buy the eufy Omni S2 if you want eufy's best: 30,000Pa suction, HydroJet 2.0 electrolyzed-water mopping certified for germ removal, a hot wash and hot-air dry cycle, a five-layer allergen filter and 3D obstacle recognition.

Buy the Eufy Omni C28 if you want the same hands-off routine for less: LiDAR mapping with no-go zones, a self-rinsing HydroJet roller mop, a 5-in-1 station that empties into a 3L bag, washes, dries and refills, and quiet 55dB operation.
