Data from Amazon and official Dreame and iRobot sites.

The iRobot Roomba Max 705 Combo leans on broader smart-home integrations, including Matter, Apple HomeKit and Samsung SmartThings, plus a dock that washes and dries its mop pad automatically rather than by hand. Both use LiDAR navigation with multi-room mapping and no-go zones, and both self-empty their dustbin at the dock. Buyers who want reliable vacuuming, a longer warranty and a lower price should pick the Dreame D20 Pro Plus; buyers who specifically want the widest smart-home ecosystem support and a self-washing mop, and can tolerate the reliability complaints some owners report, may still choose the iRobot Roomba Max 705 Combo.
