What the differences mean

Suction power

The Ecovacs DEEBOT T80S Omni is rated at 24,800 Pa and the iRobot Roomba 505X at 7,000 Pa. On rugs and embedded hair the Ecovacs pulls considerably more in a single pass.

Battery life

Ecovacs rates the DEEBOT T80S Omni at 236 minutes and iRobot rates the Roomba 505X at 180 minutes, so the Ecovacs covers larger floors before it returns to recharge.

Water tank

The Ecovacs DEEBOT T80S Omni lists a 4 L tank against 3 L on the iRobot Roomba 505X, giving it longer mopping runs between refills.

Onboard bin

The iRobot Roomba 505X carries a 295 ml onboard bin against 220 ml on the Ecovacs DEEBOT T80S Omni, though both docks empty the robot automatically.

Mop style

The Ecovacs DEEBOT T80S Omni uses a self-washing OZMO roller cleaned with hot water at the dock, while the iRobot Roomba 505X relies on lifting mop pads. Both dry the mop after washing.

Dock dust bag

The Ecovacs DEEBOT T80S Omni has a 3 L dock dust bag, and iRobot does not publish the dock capacity of the Roomba 505X.

What owners say

Owners of both pair a self-emptying, self-washing dock with reliable LiDAR navigation, and both groups name hands-off maintenance as the reason they stopped thinking about floor care. Ecovacs DEEBOT T80S Omni owners single out how quiet it runs, so it can work through calls or naps, and how strongly it lifts pet hair from rugs and hard floors, while their main gripe is the app, which they find capable but clunky when editing maps and no-go zones. iRobot Roomba 505X owners also praise pet-hair pickup and the large water reservoir, but the complaint they repeat is noise on deep-clean runs, along with the odd fiddly Wi-Fi pairing or map reset.
