Updated October 2026
Data from Amazon and official Dreame and Roborock sites.
2026 verdict
One dock automates the mop while the other just empties the bin, and that is why the Roborock Saros 20 Sonic beats the Dreame D20 Air Plus as the more complete robot vacuum of this pair.

It brings 36,000 Pa of suction, a 4 L water tank, a self-washing and self-drying mop with automatic detergent, a slim 79.8 mm body and support for Matter, Apple Home and both Wi-Fi bands. The Dreame D20 Air Plus answers with a three year warranty, a much larger 4 L dock bag rated for months, a lower price and strong suction of its own, but its flat pad only refreshes hard floors. Choose the Roborock Saros 20 Sonic for real mopping and platform reach, and the Dreame D20 Air Plus for value and a mostly vacuuming job.

What the differences mean

Mopping

The Roborock Saros 20 Sonic washes, dries and doses its mop at the dock and lifts it over carpet. The Dreame D20 Air Plus uses a flat pad fed by a 280 ml tank on the robot, with no washing, drying or lifting, so it only refreshes floors.

Suction

The Roborock Saros 20 Sonic is rated at 36,000 Pa and the Dreame D20 Air Plus at 20,000 Pa. Both are strong on hard floors, but the Roborock has more headroom for thick carpet and heavy debris.

Dock bag and warranty

The Dreame D20 Air Plus empties into a 4 L bag rated for months and carries a three year warranty, against a 2.7 L bag and one year on the Roborock Saros 20 Sonic. For a set-and-forget vacuum, that is the Dreame's strongest ground.

Smart home support

The Roborock Saros 20 Sonic supports Matter, Apple Home, SmartThings, Alexa, Google Home and Home Assistant over both Wi-Fi bands. The Dreame D20 Air Plus stops at Alexa, Google Home and Home Assistant.

Body and dock size

The Roborock Saros 20 Sonic stands 79.8 mm tall with a 10.3 kg dock, while the Dreame D20 Air Plus is 94.7 mm with a light 2.65 kg dock. The Roborock reaches under lower furniture, the Dreame is the easier dock to place.

What owners say

Owners of the Dreame D20 Air Plus are clear about what they bought it for, and it delivers: repeated reports of suction pulling up dog and cat hair, crumbs and dust that earlier robots left behind, and an anti-tangle brush design that several long-haired owners say they have never had to untangle. Navigation is the second theme, with accurate mapping in minutes and a methodical perimeter-then-rows route that finishes a small home well under an hour. The dock that empties into a 4 L bag is what makes them forget the robot for days, and value comes up constantly. The recurring caveats are a flat mop pad that only refreshes floors, hand refills of its 280 ml tank, and a tall LiDAR turret that blocks some under-furniture.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
