What the differences mean

Where the dirt goes

The Dreame D20 Air Plus self-empties a 220 ml bin into a 4 L dock bag, described as lasting up to 120 days. The iRobot Roomba 205 does not self-empty. It compacts debris inside the robot, on a small charger, and you still empty it. If the goal is to stop opening a bin after every run, the Dreame D20 Air Plus is the one with a dock. The iRobot Roomba 205 is the one without a tower to place.

Suction and a light mop

The Dreame D20 Air Plus is rated at 20,000 Pa and can mop from a 0.28 L tank on the robot. There is no mop washing, no drying, no mop lifting and no detergent. The iRobot Roomba 205 is rated at 7,000 Pa and does not mop. Both list carpet cleaning. The mop on the Dreame D20 Air Plus is a damp pad you refill, which owners treat as a supplement, not a replacement for washing a floor by hand.

Runtime, noise, warranty

The Dreame D20 Air Plus is rated for 150 minutes, about 4.5 hours to charge, 76 dB and a 3 year warranty. The iRobot Roomba 205 is rated for 120 minutes, about 5 hours to charge and a 1 year warranty. Its noise level is not documented, so 76 dB is not a win or a loss against it. Both recharge themselves. The longer warranty and the longer rated run are both on the Dreame D20 Air Plus.

Wi-Fi and assistants

The iRobot Roomba 205 uses 2.4 GHz and 5 GHz Wi-Fi and lists Alexa and Google Home, not Home Assistant, Apple HomeKit or Matter. The Dreame D20 Air Plus uses 2.4 GHz only and lists Alexa, Google Home and Home Assistant, and not Apple HomeKit or Matter. The iRobot Roomba 205 lists Bluetooth and the Dreame D20 Air Plus does not document it, so it is not scored. A 5 GHz-only network points to the iRobot Roomba 205. A Home Assistant home points to the Dreame D20 Air Plus.

What owners say

Owners of the Dreame D20 Air Plus and the iRobot Roomba 205 both bought for pet hair and both like LiDAR that does not wander at random. Dreame D20 Air Plus owners single out suction they say beats older robots, brushes that do not wrap long hair, and a bag they leave for weeks. They treat the flat pad as a light refresh, not a real mop, because they still fill a tank on the robot. iRobot Roomba 205 owners single out debris pressed down inside the machine and a charger that is not a tower. They complain one charge often fails to finish a floor and that cords and mats stall it. The Dreame group is talking about a bag. The iRobot group is talking about a bin in the robot.
