Ecovacs DEEBOT T80S Omni vs Ecovacs DEEBOT T90 Omni

Two generations of the same OZMO roller mop platform, separated mainly by suction and battery: the Ecovacs DEEBOT T90 Omni pulls 30,000Pa against the DEEBOT T80S Omni's 24,800Pa, runs 260 minutes to 236, and carries a larger 250ml onboard bin, enough to make it the stronger robot vacuum overall between this pair. Curiously, the older DEEBOT T80S Omni counters with the broader smart home reach, adding Apple HomeKit and Samsung SmartThings support through Matter where the T90 Omni is limited to Google Home and Alexa, and it also holds a bigger 3L dock bin against the T90's 2.5L, all while costing less. Both machines share the same hot-water self-washing roller mop, 4L water tank, LiDAR navigation and self-emptying dock, so the day-to-day cleaning experience is close either way. Buyers who want the strongest suction and longest runtime should pick the Ecovacs DEEBOT T90 Omni; those who want Matter-based smart home support, a bigger dock bin and a lower price should choose the Ecovacs DEEBOT T80S Omni.
