ECOVACS DEEBOT T90 Pro Omni: Specs, Features, Pros & Cons
The headline here is a very large suction figure, and it is worth saying plainly that past a certain point that number is marketing arithmetic. What matters more is the engine behind it — the airflow figure, which is what actually moves debris.
The mop is a single roller rather than a pair of spinning pads, and the dock does the work: washing it in warm water, drying it with hot air, refilling, emptying and dosing detergent automatically.

Editor’s note
The headline on the T90 Pro Omni is 30,000 Pa of suction, and it is worth saying plainly that past a certain point that number is marketing arithmetic. What matters more is the engine behind it: ECOVACS quotes 16 litres per second of airflow, which is the figure that actually moves debris, and a floating main brush with an anti-tangle side brush. On the spec sheet it is one of the strongest vacuums in this category.
The mop is a single microfiber roller rather than a pair of spinning pads, and the dock does the work: it washes the roller in warm water, dries it with hot air, refills from a four-litre clean tank, empties the bin into a 2.5-litre bag and doses cleaning solution automatically. ECOVACS rates the mopping range at 400 square metres per tank. The roller lifts 15 mm over carpet, and ultrasonic carpet detection decides when. Obstacle avoidance combines structured light with an RGB camera, and navigation is a mini-ToF sensor embedded in a body only 95 mm tall, which is the practical win here: it fits under furniture that defeats most LiDAR-turret robots.
The limitation I would weigh is runtime. ECOVACS quotes 120 minutes in standard mode on hard floor from a 4,000 mAh cell, which is modest for a flagship; the 350-minute figure in its table is for a deep-wash cycle with recharges, not one run. In a large home it will return to the dock mid-clean, and it does resume, but a 200-minute rival covers more floor per sitting. Standard-mode noise is 60 dBA, which is quiet for the power.
If you have low furniture and want a roller-mop robot with a genuinely complete dock, this is a strong pick. If your house is large and open, the battery is the number to look at first.

The bottom line
The ECOVACS DEEBOT T90 Pro Omni earns a VS Score of 55, a solid mid-pack result among the 50 robot vacuums we compare here.
- Who it’s for
- Homes with low sofas and beds where a 95 mm body matters, and buyers who want a roller mop with a dock that washes, dries, refills and doses detergent without being asked.
- Who should look elsewhere
- Large open-plan homes: the 4,000 mAh cell gives a quoted 120 minutes in standard mode, so it will dock mid-clean. Also not for anyone who prefers spinning-pad mops for scrubbing grout.
- The trade-off that matters
- Top-tier suction and airflow in a very low body, against a modest single-charge runtime and a roller-mop design that some prefer less than dual spinning pads.
- The main alternative
- ECOVACS DEEBOT X8 PRO OMNI – the roller-mop sibling one tier up, if you want the same mopping approach with a larger battery; or a Roborock Qrevo Curv if you would rather have dual spinning mops.
The VS Score is calculated from the weighted specifications above, measured against every other robot vacuums we track — a shortlisting guide, not a substitute for your own priorities. See how we score.
