Dreame D20 Air Plus vs Roborock Saros 20

Full Robot Vacuums comparison in 2026

Updated October 2026
Data from Amazon and official Dreame and Roborock sites.
2026 verdict
Hands-off mopping is the dividing line: the Roborock Saros 20 washes, dries and refills its own mops, so it beats the Dreame D20 Air Plus for most homes.

On top of that it brings 36000 Pa of suction, a 200 minute battery, a 4 L water tank, 5 GHz Wi-Fi, a slim 79.8 mm body and Matter, Apple Home and SmartThings support. The Dreame D20 Air Plus is a far cheaper robot vacuum that still self-empties into a larger 4 L bag, pulls 20000 Pa and carries a three-year warranty against one, but its mop is a flat pad with a small tank on the robot. Buy the Roborock Saros 20 if you want a flagship that cleans itself, and the Dreame D20 Air Plus if vacuuming is the job and the budget is tight.

What the differences mean

Mopping and dock

The Roborock Saros 20 dock washes its mops in hot water, dries them, refills water and doses detergent, and the mops lift over rugs. The Dreame D20 Air Plus has a fixed flat pad with a 0.28 L tank on the robot and none of that, so it only supplements hand mopping.

Suction

The Roborock Saros 20 is rated at 36000 Pa against 20000 Pa. Owners of the Dreame D20 Air Plus already find it strong, so the extra matters most on deep carpet.

Height

At 79.8 mm the Roborock Saros 20 slips under furniture the 94.7 mm Dreame D20 Air Plus cannot reach.

Dust bag and warranty

The Dreame D20 Air Plus dock takes a 4 L bag against 2.5 L and comes with three years of warranty against one, the two places where the cheaper robot comes out ahead.

What owners say

Owners of both robots praise how much dust and pet hair they pull up and how quickly they map a home. Dreame D20 Air Plus owners single out anti-tangle brushes that never need untangling, quiet standard suction and value against robots costing several times more, and they accept the mop as basic, mention a bagged dock and note the LiDAR turret stops it under some furniture. Roborock Saros 20 owners talk about an app that labels rooms by itself, a low profile that finally cleans under their furniture, reliable avoidance of cables and pets and a camera for checking on pets, while they complain about no detergent in the box, inconsistent threshold climbing and faster battery drain on deep-clean runs.

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.
