2026 verdict
The Ecovacs DEEBOT T90 Omni is the more capable robot vacuum here, and it separates itself on suction, runtime and mop technology.
It moves 30,000 Pa against 11,000 Pa on the Ecovacs DEEBOT T30S Combo, runs 260 minutes against 200, and washes its roller with water up to 75 degrees Celsius while dosing detergent automatically. The Ecovacs DEEBOT T30S Combo answers with the cordless handheld that empties into the same station, a larger 3 L dock bin against 2.5 L, and a slightly larger 275 ml onboard bin against 250 ml. Neither supports Apple Home, SmartThings or Matter. Pick the Ecovacs DEEBOT T90 Omni for hard floors, long hair and carpet in a big home, and the Ecovacs DEEBOT T30S Combo if above-floor cleaning in one box is what you need.

What the differences mean
Suction
30,000 Pa against 11,000 Pa is a wide gap. The Ecovacs DEEBOT T90 Omni is a flagship-grade vacuum, while the Ecovacs DEEBOT T30S Combo is aimed at everyday debris.
Mop technology
The Ecovacs DEEBOT T90 Omni's OZMO Roller 3.0 scrubs while fresh water rinses it and doses detergent automatically, a step past the roller setup on the Ecovacs DEEBOT T30S Combo.
The handheld
The Ecovacs DEEBOT T30S Combo includes a cordless handheld that empties into the shared station, which is the one thing it does that the Ecovacs DEEBOT T90 Omni cannot.
Runtime
The Ecovacs DEEBOT T90 Omni runs 260 minutes against 200, so it finishes a large floor with less risk of a recharge.
Dock capacity
The Ecovacs DEEBOT T30S Combo's 3 L dock bin edges the 2.5 L bin on the Ecovacs DEEBOT T90 Omni, a small advantage in how long either can go between emptyings.
Which one to buy if
- you need above-floor cleaning in the same purchase
The Ecovacs DEEBOT T30S Combo includes a cordless handheld that docks and empties into the same base.
- long hair and hard floors are the main job
The Ecovacs DEEBOT T90 Omni pairs a self-washing roller with an anti-tangle brush and 30,000 Pa of suction.
- you want the strongest suction in this pair
30,000 Pa against 11,000 Pa gives the Ecovacs DEEBOT T90 Omni far more pull.
- you clean a large floor plan
The Ecovacs DEEBOT T90 Omni runs 260 minutes against 200, with a quieter 60 dB rating.
- you want the larger dock bin
The Ecovacs DEEBOT T30S Combo's 3 L dock bin holds more than the 2.5 L bin on the Ecovacs DEEBOT T90 Omni.
- + Onboard Dustbin Capacity: 275ml
- + Dock Dustbin Capacity: 3L
- - Battery Life: 200 minutes vs 260 minutes

What owners say
Ecovacs DEEBOT T90 Omni owners, several of them coming from Roborock and Roomba machines, describe the self-washing roller as a generational change: it scrubs with fresh water instead of dragging a wet pad, and leaves no streaks or water marks. They also single out how quiet it runs at 30,000 Pa and how the anti-tangle brush copes with long hair. Their complaints land on software, with occasional random remapping and odd routing, on the absence of Apple Home, SmartThings and Matter, and on the machine's size and tall station.
