Eufy has released the OMNI S2, a next-generation robot vacuum designed to expand the brand’s premium smart cleaning lineup. The new model combines an extending mop roller and side brush design, a self-cleaning mopping system, and a fully automated base station—features increasingly associated with high-end autonomous cleaners.

What Makes the OMNI S2 Stand Out
Corner and Edge Cleaning Design
Eufy says the OMNI S2 places added emphasis on edge and corner coverage. The robot uses an extending side brush system designed to reach into corners, while its roller mop adjusts position near walls and edges to improve contact along baseboards and room boundaries. Together, these features are intended to help reduce missed debris and improve cleaning consistency around the perimeter of a room.
High Suction Performance
According to Eufy, the OMNI S2 delivers up to 30,000 Pa of suction using its AeroTurbo™ 2.0 system. The company says this design is intended to maintain strong, consistent suction through a multi-cyclone separation process, helping pull debris from both carpets and hard floors with minimal performance drop-off.
HydroJet™ Self-Cleaning Roller Mop
One of the OMNI S2’s headline features is its HydroJet™ roller mopping system. Eufy says the mop continuously cleans itself during operation and uses electrolyzed water to sanitize hard floors while scrubbing stubborn messes. The company claims the system can achieve 99.99% sterilization, targeting dried-on residue and everyday spills.
CleanMind™ AI Navigation and 3D Mapping
The OMNI S2 is powered by CleanMind™ AI, which Eufy says enables 3D mapping and adaptive navigation. Using RGB vision and object recognition, the system is designed to detect and avoid more than 200 object types while optimizing cleaning paths throughout the home.
CES 2026 Coverage Note
Eufy recently showcased the OMNI S2 at CES 2026, where it received a CES 2026 Honoree in Home Appliances Award. Vacuum Wars will be sharing additional details and hands-on impressions from the show floor in an upcoming feature. See our full CES coverage here.
Comprehensive Smart Features
Beyond its core cleaning systems, the Eufy OMNI S2 includes several automation-focused enhancements designed to reduce hands-on maintenance:
- A 12-in-1 UniClean™ base station for automated dust emptying, mop washing, drying, and water refilling
- Adaptive carpet lift with automatic suction adjustment
- DuoSpiral™ detangle brushes designed to help resist hair wrap
Final Thoughts
With the OMNI S2, Eufy is clearly positioning itself at the top end of the robot vacuum market. On paper, the combination of high suction, a self-cleaning roller mop, AI-driven navigation, and an all-in-one base station places the Omni S2 among the most feature-rich robot vacuums announced this year. Vacuum Wars looks forward to evaluating how these claims translate into real-world performance.
