Ecovacs Deebot T80 Omni

What testers say about the Ecovacs Deebot T80 Omni

The Ecovacs Deebot T80 Omni is the first T-series model with the OZMO roller mop from the pricier X-series: a roller that is wetted with clean water while mopping, wrings the dirty water out and extends along edges. The Omni station empties the bin into a three-liter bag, washes the roller with hot water, dries with hot air and cleans itself with eight spray nozzles. The robot navigates with an embedded lidar and recognizes obstacles with a camera and 3D structured light. Vacuum Wars bought one, tested it for weeks and made it runner-up in its mid-2025 awards.

Mopping was exceptional: 139.5 points on dried stains against an average of 93, with just 0.3 grams of water left behind where the average robot leaves over a gram, for a combined mop score of 287 against 171 on average and just under the flagship X9 Pro Omni. Flattened pet hair was picked up at 99 percent, nothing was wrapped around the V-shaped brush after the long-hair test, and on the standard course it dodged 11 of 12 obstacles. One charge covers more than 1,080 square feet and the app offers multiple maps, a 3D floor plan, live video and a built-in voice assistant.

The criticism: during the test the robot froze three times for no discernible reason, under a coffee table and against table legs, with an error message; the testers put it down to a firmware glitch and placed no-go zones around the table. On the tougher obstacle course it avoided 7 of 12 items, the crevice test left more debris behind than desired, the station doses no detergent, the side brush does not extend and at nearly 3.9 inches it does not fit under the lowest furniture. Anyone mainly after an excellent mopping robot for less than the flagship is well served here.
