What the differences mean
Suction
The iRobot Roomba Max 775 Combo Robot + AutoWash Dock rates 30,000 Pa against 24,800 Pa for the Ecovacs DEEBOT T80S Omni. The gap is narrower than in most pairs, but the Roomba still pulls slightly harder.
Runtime
The Ecovacs DEEBOT T80S Omni is rated for up to 236 minutes against 180 for the iRobot Roomba Max 775 Combo Robot + AutoWash Dock, and it recharges in about 3.5 hours against 6.
Detergent
The iRobot Roomba Max 775 Combo Robot + AutoWash Dock dispenses cleaning solution on its own. The Ecovacs DEEBOT T80S Omni has no automatic dispenser, so cleaning solution is added to the tank by hand.
Mop type
The Ecovacs DEEBOT T80S Omni uses an OZMO roller mop washed with 75 C hot water and a triple lift system. The iRobot Roomba Max 775 Combo Robot + AutoWash Dock uses pads that the dock washes and dries.
Dock footprint
The iRobot Roomba Max 775 Combo Robot + AutoWash Dock needs a large permanent spot, and iRobot publishes no water tank or bin sizes for it. The Ecovacs DEEBOT T80S Omni uses a 4 L clean water tank and a 3 L dock bin, so both figures are documented.

What owners say
Owners of the Ecovacs DEEBOT T80S Omni describe a clear step up from older robots that bumped blindly into furniture. They praise the OMNI dock's auto-empty, 75 C hot-water mop washing and hot-air drying as the feature that removes daily maintenance, and they report strong suction for pet hair, crumbs and dust on rugs and hard floors, quiet running that suits work calls or nearby naps, and reliable LiDAR navigation that returns to the dock and resumes after recharging. The recurring complaint is the companion app: mapping is solid, but editing the map to exclude thresholds or areas feels less refined, especially on iOS. They also note there is no automatic detergent dispenser and no child lock, and that a minority reported reliability hiccups.
