What the differences mean

Suction power

The Roborock Saros 20 Sonic is rated at 36,000 Pa and the Ecovacs DEEBOT T90 Omni at 30,000 Pa. Both are very strong, so the difference shows on deep carpet more than on everyday hard-floor pickup.

Height and reach

At 79.8 mm the Roborock Saros 20 Sonic is thinner than the 95 mm Ecovacs DEEBOT T90 Omni, so it slides under lower furniture and cleans where the taller robot cannot fit.

Noise and battery

The Ecovacs DEEBOT T90 Omni is rated for 260 minutes at 60 dB, while the Roborock Saros 20 Sonic is rated for 190 minutes at 64 dB. The Ecovacs runs longer and quieter, and the Roborock recharges faster in about 2.5 hours.

Smart home platforms

The Roborock Saros 20 Sonic 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.

Mopping type

The Ecovacs DEEBOT T90 Omni uses a wide self-washing roller that scrubs with fresh water. The Roborock Saros 20 Sonic washes and dries mop pads at the dock, a design owners describe as gentler on hard floors.

What owners say

Ecovacs DEEBOT T90 Omni owners are unusually enthusiastic about the mopping. Many moved from Roborock machines or older Roomba models and say the roller that washes itself with fresh water was the feature that changed their opinion of a robot mop, leaving floors without the streaks and water marks their old pads produced. They also highlight how quiet it runs for its suction, the anti-tangle brush that copes with long hair, and a station that empties, refills, washes at 75C, dries and dispenses detergent automatically. Their main criticism is software: the app and mapping are called adequate rather than polished, with occasional odd routing.
