The Deebot T90 Pro Omni is interesting because despite it being classed as a mid-tier model in Ecovacs’ line of robot vacuums, it is anything but. It sits below the company’s flagship Deebot X11 Omnicyclone that I’ve reviewed previously, but comes with a new roller-style mopping system, a docking station that cleans and dry the wet mop, and almost double the suction power (30,000Pa versus 19,000Pa on X11). But after spending some time with it at home, it became pretty clear that while it’s capable, it still needs a bit more handholding than I expected.
Wet mopping perfected?
The first thing that tripped me up was the initial mapping process, which, to be honest, I expected to be straight-forward for all, if not most, modern robot vacuums. Most that I’ve tested I’ve tested recently, such as those from Dreame, Mova and even Ecovacs, get it right on the first pass, or at least close enough that you don’t feel the need to tweak anything. The T90 Pro Omni didn’t quite manage that. For whatever reason, it decided that my two separate bedrooms were actually one single combined space, which threw off room segmentation right from the start, and at the same time it somehow exaggerated the size of my living room in the app, stretching the digital layout beyond what actually exists physically. None of this is impossible to fix – you can go in and manually adjust room boundaries in the Ecovacs app – but it does chip away at that frictionless setup experience that most of us expect today.
Overall, the T90’s navigation capability is generally fine, but it doesn’t quite recognise obstacles as accurately as I expected from it. For instance, it got itself stuck on a floor mat that most competing models would either avoid or gently climb over without getting caught. To be fair, it doesn’t happen every single cleaning run, but often enough during my tests that I’ve concluded the T90 requires some manual intervention beforehand: putting away cables on the floor, removing mats, and other small or flat obstacles that may get stuck beneath the T90’s rollers.

Where the T90 starts to turn things around, though, and where it genuinely impressed me is with its mopping performance. Like the X11 Omnicyclone, the T90 Pro Omni moves away from the usual dual spinning mop pads and instead uses Ecovacs’ new Ozmo Roller 3.0 system, but this newer version feels like a proper step up rather than a minor revision. The roller itself is larger, spins faster at up to 200rpm, and applies more pressure against the floor than the older 2.0 system that is featured on the X11, and you can actually see the difference after a run. Floors don’t just look clean – they feel it too. Compared to something like the Dreame X60 Ultra with its spinning mops, and even against its higher-end X11 brethen, the T90 comes across as more consistent, especially when dealing with dried stains or light kitchen grime. The roller also extends slightly to the side, which helps it get closer to skirting boards and edges, so you’re not left with that thin strip of untouched floor. Suffice to say, it handled dried stains, minor spills, and general daily dirt exactly the way I’d want it to, and at this point, I’ll say it again – if you care about mopping performance above everything else, a roller system still do a better job than spinning mop ones, and right now, the T90’s Ozmo Roller 3.0 is one of the better systems I’ve come across.
