The newest
Upgrades over the S1 Pro:

The Omni S2 has stronger suction and features some upgrades:
- Stronger suction

- Identifies mess and adjusts cleaning strategy to remove it
Intelligent Carpet Cleaning: S2 intelligently adapts to different carpet types, lifts its chassis to clean carpets up to 2 in thick, and raises the roller mop to prevent wetting.
As to mopping, there is not much new. The S2 has a built-in fragrance dispenser that sprays fragrance while it cleans.
Better at everything
eufy Robot Vacuum Omni S1 Pro
The premium S1 has two modifications, the S1 and S1 Pro:
The S1 robot utilizes AI.See for obstacle avoidance, while the S1 Pro robot is equipped with a more advanced 3D MatrixEye system. Furthermore, the S1 Pro robot features an electrolyzed water disinfection function, which the S1 robot lacks. Another significant difference is the display screen on the base station, which is included with the S1 Pro robot but not with the S1 robot. The S1 top buttons by the LCD is not touch-sensitive.
A newer design body is made for corner cleaning.
10-in-1 UniClean Station offers auto emptying, auto washing, auto refilling, auto heated air drying, Eco-Clean Ozone, auto wastewater collection, auto detergent dispensing, LCD touch control, sealed dust bag, and 20% faster charging*.
*Based on the eufy internal test, charging is 20% faster than the previous generation's.
The S1 Pro looks to be better in almost every way
Summing up
The eufy Omni S2 is a better buy for carpeted homes.
