Six UV-C LEDs under the robot, electrolyzed water in the mop and a boiling-hot wash back at the dock. eufy built its new flagship around germs as much as dirt.
Omni S2 Pro is on sale now at eufy, one rung above the Omni S2. eufy says the light and the water together kill 99.99% of bacteria on floors, a lab figure from TÜV SÜD and SGS testing, not a promise for your kitchen.

What does the UV-C light do?

It treats the strip of floor the robot has just mopped. The LEDs shine across a 120-degree beam at 270 to 280 nm, the germicidal band, on every pass.
How hot does the mop get?

The 11.4-inch roller mops with 55°C water from 32 jets, pressing down at 16 N and spinning at 240 RPM. Back at the UniClean station it’s washed at 100°C, up from 60°C on the S2, and dried. The dust bag and filter now carry a PHMB antibacterial treatment.
Is it worth paying more than the Omni S2?

If germs are why you mop, yes. UV-C and the hotter wash are the real changes, and suction climbs from 30,000 to 40,000 Pa. It also recognizes 360-plus objects and climbs two-tier thresholds up to 2.76 inches.
Launch orders add perks eufy values at $189.98: an accessory kit, a one-year extended warranty and 45-day returns. The eufy app takes another $200 off for now.
The S2 Pro isn’t on Amazon yet. The Omni S2 is, with the same electrolyzed water and roller mop, minus the UV-C, the hotter wash and the extra suction.

For a home with a crawling baby or a shedding pet, I’d pay the difference for the Pro.
