Disclosure — some links on this page go to Amazon, and we earn a commission if you buy through them. It costs you nothing extra and it does not change what we recommend or in what order. The full disclosure.
ECOVACS publishes 9 of the 9 specifications we track for this model, which is more than most. Everything below is quoted from ECOVACS’s own material, with the page it came from linked on each row. We have not handled this machine.
This is the machine that replaced the X8 PRO OMNI, and it is an unusually clean swap: the climb height, the mop lift, the on-board bin and the body height are all identical to the model it succeeds. If you were considering the X8 before it sold out, almost everything you liked about it on paper is still here.
The OZMO Roller remains the reason to look at it. Instead of a pad that gets dirtier as it crosses your floor, the roller is rinsed continuously while it turns, so in principle the water hitting the last square meter is as clean as the water that hit the first. ECOVACS states mop washing across a 40C to 75C range rather than a single temperature, which is more specific than most makers manage, and backs it with a 3L dock bag.
Two things moved in the wrong direction and we are not going to paper over them. Suction dropped from the 18,000 Pa ECOVACS claimed for the X8 to 16,600 Pa here, which is a rare case of a successor publishing a smaller headline number. And the 20mm climb figure is unchanged, which means it is still at the low end of our threshold table — several cheaper machines clear more. Buy it for the roller, not for the sills.

What the sheet says it does well, and what it does not
Strengths
- OZMO Roller self-washes during the run rather than only at the dock
- Publishes a threshold figure and states the condition (with mop attached)
- Mop washing is temperature-controlled across a stated 40C to 75C range rather than a single number
Limits
- 20mm climb is among the lowest published figures here
- 0.22L on-board bin is small, so it leans hard on the dock
- 16,600 Pa is lower than the model it replaces, which stated 18,000 Pa
Who it is for
Hard floors that actually get dirty — kitchens, entryways, homes with dogs.
Who should skip it
Your sills are tall. ECOVACS publishes 20mm with the mop attached, which is at the low end of our threshold table.
We name it as the pick to skip on one page, for reasons specific to what those pages are about:
- Robot vacuums for laminate floors — This is the best mopping hardware in our comparison and we recommend it elsewhere without hesitation. On laminate specifically, a continuously rinsing roller puts more water on the floor than a damp pad does, and laminate's one real weakness is water reaching the core through a seam. If your laminate is older or the joins have opened at all, buy the gentler mop.

How we assessed this
By reading what ECOVACS publishes and recording it with its source. We have never owned, handled or measured this machine, and nothing above is written as though we had. Where the manufacturer publishes nothing, the row says so rather than borrowing a number from somewhere else. The full method is on how we pick, and if a figure here does not match the page it links to, tell us and we will correct it with a date.
Questions people actually ask
+ Does ECOVACS publish a threshold climb height for the ECOVACS DEEBOT X9 PRO OMNI?
Yes — 20mm with the mop attached. ECOVACS states the condition alongside the figure, which is unusual and useful — a mop combo's climb is not the same as a bare chassis's. Compare it against every other model on the cross-brand climb table.
+ What suction does the ECOVACS DEEBOT X9 PRO OMNI have?
ECOVACS states 16,600 Pa. Lower than the 18,000 Pa ECOVACS stated for the X8 PRO OMNI this model replaces. ECOVACS also states a 16.3 L/s airflow figure, which almost nobody else publishes. Remember that pascal ratings are not standardized between manufacturers, so that figure ranks this model within ECOVACS's own range and does not compare across brands — the full explanation.
+ Is the ECOVACS DEEBOT X9 PRO OMNI good for pet hair?
Its main brush is described as cyclone-directed anti-tangle main brush, zerotangle 3.0, which is the specification that matters most in a hair-heavy house — more than suction. The brush comparison sets out what each design does.
+ Can the ECOVACS DEEBOT X9 PRO OMNI mop over carpet?
ECOVACS states a mop lift of 10mm automatic. ECOVACS calls the mechanism the Triple Lift System and states that on carpet it raises the mop to prevent wetting while boosting suction. Compare that against your own pile depth rather than against other models — mop lift compared.
+ Who should skip the ECOVACS DEEBOT X9 PRO OMNI?
Your sills are tall. ECOVACS publishes 20mm with the mop attached, which is at the low end of our threshold table.
