What the differences mean

Suction power

The Ecovacs DEEBOT T90 Omni is rated at 30,000 Pa against 22,000 Pa for the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock. Both handle daily debris, but the Ecovacs pulls more out of carpet and worked-in pet hair.

Battery life

The Ecovacs DEEBOT T90 Omni is rated at 260 minutes and the iRobot Roomba Plus 515 Combo Robot + AutoWash Dock at 200 minutes. Over a whole floor the Ecovacs finishes in one go more often, without pausing to recharge.

Mopping system

The Ecovacs DEEBOT T90 Omni uses a roller that rinses itself continuously and is washed at the station with hot water, then dried with hot air. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock uses pads that are washed and heat-dried but that iRobot describes as decent rather than thorough.

Automatic detergent

The Ecovacs DEEBOT T90 Omni station dispenses cleaning solution by itself, so the roller always washes with detergent. The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock has no auto-dispensing, so solution is added by hand or skipped.

Body height and platforms

The iRobot Roomba Plus 515 Combo Robot + AutoWash Dock is 84 mm tall, low enough for most beds, while the Ecovacs DEEBOT T90 Omni is a taller machine. On smart home support, the Ecovacs adds Home Assistant through the Ecovacs integration, where iRobot stays with Alexa and Google Home.

Which one to buy if

What owners say

Owners of both robots describe mapping and app control as the step up from older machines, with rooms labelled on their own and pads kept fresh by a self-cleaning dock. Ecovacs DEEBOT T90 Omni owners are the more enthusiastic about mopping, saying its self-washing roller scrubs rather than smears and leaves no streaks or circular marks, and many note how quiet it stays despite the suction. They also credit the anti-tangle brush with ending long-hair clogs. iRobot Roomba Plus 515 Combo Robot + AutoWash Dock owners focus on vacuuming, pet-hair pickup and the low body that reaches under beds, and they warn that its mopping is only decent and its dirty tank needs prompt emptying.
