Suction. The Ecovacs DEEBOT T90 Omni is rated at 30,000Pa, double the Eufy Omni C28's 15,000Pa, which is what shows up on embedded pet hair and in carpet. Their navigation, mop washing and self-emptying routines are otherwise closely matched.

The Eufy Omni C28, whose dock bag holds 3L against 2.5L on the Ecovacs DEEBOT T90 Omni. The gap is modest, so expect a slightly longer interval between bag changes rather than a different class of convenience.

Yes. Both the Ecovacs DEEBOT T90 Omni and the Eufy Omni C28 mop with a roller that the station washes with hot water and dries with hot air, and both lift the mop on carpet, so neither leaves a damp pad sitting in the dock.

Homes with carpet, pets or a lot of hard floor, where 30,000Pa of suction and a 4L mopping tank do real work, and where a slightly longer runtime helps finish in one pass.

Buyers who want the lower price, the quieter run at around 55dB and the roomier 3L dock bag, and who do not need the DEEBOT's extra suction because the floors are mostly hard and lightly soiled.
