Review
What this product is
Written after the analysis, from the same sources the score is built on: the manufacturer's documentation, available studies and verified owner feedback.
The Omni S2 is for carpeted homes where data security matters and budget does not. Eufy states 30,000 Pa and, unusually, 100 air watts, a 29 cm roller mop with 15 N of pressure, washing with 60 °C water, 55 °C hot-air drying, and thresholds of 3.5 cm single and 4.2 cm double. Its page says TÜV SÜD verified the robot against the ETSI EN 303 645 cybersecurity standard, the clearest security statement in this ranking.
The test record is good on carpet and obstacles. The Smart Home Hookup named it best flagship and recorded 78.8% carpet pickup, the highest of its seven robots. Vacuum Wars scores it 3.90 (sixth), with a flawless 24 of 24 obstacles and 87% of embedded sand, but rates its mopping below average. The Smart Home Hookup saw it clear 30 mm, not 50 mm.
The datasheet is the thinnest among the expensive robots: robot height, battery capacity, runtime, noise and tank volumes were not on the pages we opened. That makes the key metric half blank. At €1,499 with no discount shown it is the most expensive product here, and 24 owner reviews were listed without a visible star average.

FAQ
Frequently asked questions
What does the ETSI EN 303 645 statement on the Eufy Omni S2 mean?
Eufy says TÜV SÜD verified the robot against ETSI EN 303 645, a cybersecurity standard for connected consumer devices. It is a statement about security practice, not about cleaning performance.
Is the Omni S2 worth €1,499?
Only if carpet cleaning and obstacle avoidance are the priority. Vacuum Wars gives the €399 Ecovacs T90 Pro Omni the same overall score of 3.90, and rates the Eufy's mopping below average.
