Its 236 minute runtime beats 179, its 4 L water tank and 3 L dock bin are both larger, and it costs less, while its 24,800 Pa suction is only slightly behind the eufy 30,000 Pa. The eufy Omni S2 answers with a two-year warranty against one, a stronger roller mop, and Matter, which both robots support. Both wash and dry their mops at the dock; the T80S Omni has no automatic detergent dispenser and the eufy does. Neither fits under the lowest furniture. Pick the Ecovacs DEEBOT T80S Omni for value, runtime and a bigger tank, and the eufy Omni S2 for suction and the longer warranty.

What the differences mean

Suction

30,000 Pa against 24,800 Pa gives the eufy Omni S2 a small edge, enough to matter on deep carpet and heavy pet hair but close enough that most buyers will not feel it on hard floor.

Runtime and tank

The Ecovacs DEEBOT T80S Omni runs about 236 minutes against 179 and carries a 4 L clean water tank against 3 L on the eufy Omni S2, so it covers more floor and refills less often.

Detergent

The eufy Omni S2 doses cleaning solution automatically at its dock. The Ecovacs DEEBOT T80S Omni has no automatic dispenser, so solution goes into the water tank by hand before a mopping run.

Warranty

The eufy Omni S2 carries a two-year warranty, longer than the single year on the Ecovacs DEEBOT T80S Omni, which is worth weighing on a machine with a wash-and-dry station.

Tank and bin sizes

The Ecovacs DEEBOT T80S Omni pairs its 4 L clean water tank with a 3 L dock bin, both larger than the 3 L and 2.5 L of the eufy Omni S2, so its manual chores are spaced further apart.

What owners say

The self-emptying OMNI dock is the standout for Ecovacs DEEBOT T80S Omni owners, who describe the auto-empty, hot-water mop washing and hot-air drying as a real change to their routine, and they praise quiet operation, LiDAR mapping, reliable docking and auto-recharge. Their common complaint is the app, whose map editing feels less refined especially on iOS, along with the missing auto-detergent dispenser and the absence of a child lock. eufy Omni S2 owners praise the roller mop for lifting ingrained mud, best-in-class obstacle avoidance for cords and pet dishes, quiet running and a premium build. Their warnings are about navigation and app behaviour on complex layouts, a buggy Android app, a tall 98 mm body and uneven reliability.
