What the differences mean

Suction power

The Roborock Saros 20 Flow is rated at 36,000 Pa and the Ecovacs DEEBOT T90 Omni at 30,000 Pa. Both are very strong, so the gap matters most on deep carpet and embedded debris rather than everyday hard-floor pickup.

Smart home platforms

The Roborock Saros 20 Flow works with Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The Ecovacs DEEBOT T90 Omni reaches Alexa, Google Home and Home Assistant, but has 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 and lifts on carpet. The Roborock Saros 20 Flow uses mop pads that wash, dry and lift at the dock, a design that is simpler but generally gentler on hard floors.

Noise and battery

The Roborock Saros 20 Flow is rated for up to 301 minutes against 260 for the Ecovacs DEEBOT T90 Omni, so it goes longer between dock stops. The Ecovacs is the quieter of the two at 60 dB against 66.6 dB, a gap you would notice when it runs in the room you are in.

Height

The Roborock Saros 20 Flow is 89.8 mm tall and the Ecovacs DEEBOT T90 Omni is 95 mm, so the Roborock reaches a little further under low sofas and beds.

What owners say

Ecovacs DEEBOT T90 Omni owners describe the mopping as the reason they bought it. Several came from Roborock and older Roomba machines and say the self-washing roller that scrubs with fresh water changed their opinion of robot mopping, leaving no streaks or circular water marks where their old pads did. They also single out how quiet it runs for its suction, the anti-tangle brush that handles long hair, and a station that empties, refills, washes at 75C, dries and doses detergent on its own. The recurring complaint is the app and mapping, which owners call adequate rather than best in class, with occasional random remapping or odd routes back to the dock.
