Our take
eufy Omni S2
Fantastic when it works, but current owner feedback raises too many reliability concerns for us to recommend it confidently at a premium price.
Owners praise the cleaning and mopping quality when the robot is operating normally.
Wheel failures, docking and charging problems, navigation regressions and repeated customer-service contact are serious concerns.
Homes prioritising 30,000 pa suction.
Buyers who want a basic vacuum without mopping, advanced navigation or dock automation.
- 30,000 Pa suction — an advertised pressure figure, not a cleaning score.
- A rotating roller wipes the floor as the robot moves.
What reviewers found
The Omni S2 combines convincing carpet cleaning and obstacle avoidance with unusually divided mopping results. A replacement during one extended home review also means impressive day-to-day performance should be separated from proven long-term reliability.
Carpet and hair are clear strengths
Vacuum Wars found strong embedded-dirt and flattened-hair pickup on carpet, with no wrapping in its long-hair test. It also avoided every object in that publication’s obstacle course. Those results support its usefulness in busy pet homes, without guaranteeing it will recognise every cable or accident on a real floor.
[1]Mopping results disagree
TechRadar praised the roller’s cleaning in a home used for several weeks. Vacuum Wars recorded below-average removal of dried stains and suggested low water output as a possible explanation. The available tests therefore do not support calling it uniformly exceptional at scrubbing: routine washing and demanding dried-on marks can produce different impressions.
[1][2]A good app, with some slower runs
TechRadar found the app responsive and well organised. Vacuum Wars also liked its detailed room controls, but measured slower coverage and inconsistent climbing of a high threshold. Large floor plans or awkward transitions deserve more attention than the advertised suction figure. The onboard camera does not provide remote live viewing.
[1][2]Self-cleaning is helpful, not a reliability guarantee
TechRadar found the bin, rollers and mop remained impressively clean during daily use. However, its first unit lost communication with the dock after a month and required replacement. The reviewer praised customer service and the replacement worked well. This is a documented failure and resolution, not a measured failure rate.
[2]Consumables add to ownership costs
The same home review highlighted the cost of Eufy’s detergent, replacement parts and optional fragrance refills. Its cleaning convenience is most persuasive for someone who will use both vacuuming and mopping regularly and is comfortable maintaining the dock and replenishing those supplies.
