eufy has just launched the Omni S2 Pro cleaning robot, an upgrade of the Omni S2 that appeared at CES 2026, aimed at families with babies, pets or people with allergies. The most notable point is that the machine attaches a UV-C light on the underside to disinfect the floor immediately while running, combined with electrolyzed water, and eufy calls this the first robot vacuum cleaner to combine these two technologies. In addition, the suction force increases to 40,000 Pa, the HydroJet 3.0 roller mop wipes with hot water and the Omni Station washes the rag with 100°C water.

Main specifications:

• Maximum suction force 40,000 Pa, suction capacity 100AW
• Disinfection: 6 UV-C LEDs 270–280 nm, beam angle 120°; Electrolyzed water (hypochlorous acid + ozone)
• Kills 99.99% of bacteria on floors (UV-C + electrolyzed water, according to TUV and SGS)
• AeroTurbo 3.0 Multi-Cyclone filter, removes 99.99% of allergens, PHMB antibacterial filter and dust bag
• HydroJet 3.0 roller: 11.4 inches (~29 cm) long, 32 water jets, 240 rpm, 16 N pressure, 55°C hot water cleaning
• Omni Station: wash rags with 100°C hot water, dry, self-empty trash
• Avoid obstacles: AI recognizes more than 360 types of objects, 3D ToF + RGB camera, 2 line laser sensors
• Exceeds 1-story threshold 1.38 inches (~3.5 cm), 2-story threshold 2.76 inches (~7 cm)
• Robot body is 3.86 inches (~9.8 cm) high
• Deodorant incense box with 2 scents (Crisp Pine, Fresh Lavender)
• Wi-Fi, Bluetooth connection, app and voice control

Design

In general, the Omni S2 Pro keeps the familiar round robot style of the Omni series, and comes with a tall tower-shaped Omni Station that also does the washing, drying, and trash disposal. The robot's body is 3.86 inches tall, or about 9.8 cm, and in standard mode the machine will not enter furniture lower than about 4.25 inches to avoid getting stuck.

When running in UV mode, the light ring on the top of the robot will turn purple, helping you know the UV-C light is working because this type of light is invisible to the human eye.

UV-C disinfection + electrolyzed water

The bottom of the robot has 6 UV-C LEDs emitting a wavelength of 270–280 nm, each LED projects a 120° wide angle onto the floor. Simply put, wherever the robot goes, the floor is illuminated with antibacterial ultraviolet rays. According to eufy, UV rays penetrate bacterial cell walls or virus shells and destroy DNA/RNA, making them unable to reproduce. The light also turns off automatically when the robot is lifted or turned upside down, making it safe for children and pets.

In parallel, there is an electrolyzed water system: electrolyzed water creates hypochlorous acid and ozone, running straight from the station's clean water tank to the tank on the robot to clean the floor and wash rags. eufy says combining UV-C with electric water can kill 99.99% of bacteria on the floor according to tests by TÜV and SGS, but this is still lab data so the reality depends on the environment.

Vacuum and allergen filter

Maximum suction force increased from 30,000 Pa on Omni S2 to 40,000 Pa, 100AW suction capacity, and eufy promises undiminished suction force for 365 days instead of 90 days like the old version. The AeroTurbo 3.0 Multi-Cyclone filter system separates dust in a tornado style, eufy says it retains 99.99% of dust particles and retains 99% of the suction power compared to the first day.

The filter and dust bag in the station are all supplemented with PHMB antibacterial layer, along with the anti-tangle brush that eufy announced collects 100% hair and 0% tangles, suitable for dog and cat owners. When encountering carpet, the machine automatically increases suction power by one level with BoostIQ and can climb carpets up to 1.38 inches thick, lower than the 1.97 inches of the regular Omni S2.

HydroJet 3.0 Mop

The HydroJet 3.0 roller is 11.4 inches long, which eufy calls the longest in the industry, has 32 evenly sprayed water jets, rotates at 240 rpm and presses against the floor with a force of 16 N instead of 15 N as before. The new feature is that the rag uses 55°C hot water to dissolve kitchen grease, while continuously cleaning itself while wiping.

When detecting carpet, the rag raises itself 0.59 inches (about 1.5 cm) so as not to wet the carpet, and when cleaning close to the wall, the rag and edge brush self-extend so that the rag is only about 0.2 inches away from the wall. At the station, the rag washing water temperature increases from 60°C to 100°C, and according to TÜV SÜD the station eliminates 99.99% of bacteria to limit mold and odors.

AI and sensors

The CleanMind AI system uses a 3D ToF sensor combined with an RGB camera to draw a 3D map of the house, identifying more than 360 types of obstacles such as charging cords, trash cans, and shoes, up from more than 200 types on the Omni S2. Identification is processed right on the device, eufy said the data is not pushed to the cloud, and the device can avoid objects 0.39 inches (about 1 cm) high or taller.

The edge sensor has been increased from 1 to 2 line laser modules to help clean closer to the corner better, while the ability to cross the threshold of a 2-story door has increased from 1.65 inches to 2.76 inches, or about 7 cm. The machine also supports voice control, avoids carpet tassels and has an incense box with 2 deodorant scents Crisp Pine and Fresh Lavender.

Compared to Omni S2

According to eufy, S2 Pro is better than S2 in UV-C, 40,000 Pa suction force, hot water wiping, rag pressure, AI recognition, dual laser, higher threshold, 100°C rag washing and antibacterial dust bag. On the contrary, S2 can often climb thicker carpets and the station has the ability to detect dirty water to re-wash rags, so if the house does not need to be disinfected, S2 is still enough to use.
