What the differences mean

Suction power

The Roborock Saros 20 is rated at 36,000 Pa and the Ecovacs DEEBOT T90 Omni at 30,000 Pa. Both are at the top of the category, so the gap shows mainly on deep carpet and debris that has worked into the pile.

Height and reach

At 79.8 mm the Roborock Saros 20 is noticeably thinner than the 95 mm Ecovacs DEEBOT T90 Omni, so it gets under lower sofas and beds and extends cleaning into places the taller robot skips.

Smart home platforms

The Roborock Saros 20 works with Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The Ecovacs DEEBOT T90 Omni reaches Alexa, Google Home and Home Assistant, with no Apple Home, SmartThings or Matter path.

Mopping type

The Ecovacs DEEBOT T90 Omni uses a wide self-washing roller that scrubs with fresh water. The Roborock Saros 20 washes and dries mop pads at the dock, a gentler design that owners say mops well but scrubs less aggressively.

Noise and battery

The Ecovacs DEEBOT T90 Omni publishes a 60 dB sound level and a 260 minute runtime, where the Roborock Saros 20 publishes neither. If a documented battery figure and noise rating matter, the Ecovacs is the one that states them.

What owners say

Roborock Saros 20 and Ecovacs DEEBOT T90 Omni owners both rate the self-maintaining dock as the feature that changed their routine, and both groups praise quiet operation and app schedules. After that they diverge. Roborock Saros 20 owners highlight mapping that labels rooms on its own, a low chassis that reaches under furniture and reliable obstacle avoidance, and they complain about the mop solution not being included and some threshold trouble. Ecovacs DEEBOT T90 Omni owners focus on mopping, describing the roller that scrubs with fresh water as a step past the pads they used before, and rate the anti-tangle brush for long hair, while their main criticism is an app and mapping that feel adequate rather than polished.
