Key technical differences
X9 Pro OMNI (base flagship)
- ~16,600 Pa suction (BLAST system)
- OZMO Roller 2.0 / 3.0 (varies by region)
- ZeroTangle 3.0
- TruEdge 2.0
- AIVI 3D 3.0 navigation
- Strong but first-gen X9 platform.
From official specs: focuses on balanced suction + roller mopping + stable automation.
X9S Pro OMNI (refreshed flagship)
- 30,000 Pa suction (much higher airflow system)
- OZMO Roller 3.0 (updated scrub system)
- Improved continuous self-washing roller design
- TruEdge 3.0 edge cleaning
- ZeroTangle 4.0 anti-hair system
- Upgraded AI + obstacle detection stack
From ECOVACS specs, it is positioned as a higher-performance evolution of the X9 platform
In the real-world difference, the X9S Pro wins clearly
Improved
Innovations:
- FocusJet stain pre-treatment
- Larger roller mop
- Mop cover
- Stronger suction
In short:
X9S Pro OMNI
- Much stronger suction (30k Pa)
- Better edge cleaning (TruEdge 3.0)
- Better anti-hair system (ZeroTangle 4.0)
- More advanced AI cleaning logic
- More aggressive “top-end performance” tuning
The upgraded: better for carpets
DEEBOT X9 Pro OMNI
A new Blast Tech provides deep carpet cleaning
Unlike the DEEBOT X8 Pro OMNI, the newest X9 Pro OMNI features a triple lift system that adapts to the cleaning task, lifting a side brush, roller, or mopping roller as needed. The OZMO mopping combines two onboard tanks, a wide roller, and better water consumption compared to a two-pad system.
A new Blast technology combines suction and airflow for deep carpet cleaning
While higher suction drains battery life, Blast optimizes both by 3x airflow and strong suction, delivering deeper cleaning and extending runtime.
More pickup efficiency, better carpet cleaning
Even tho the robot has lower suction numbers, thanks to the Blast, it has more efficiency at deep carpet cleaning.
Which one?
- X9S PRO Omni = more aggressive roller + better self-cleaning flow
- X9 Pro OMNI = already good, but less refined
