2026 verdict
The iRobot Roomba 415X is the pick in this robot vacuum pairing, with warmer owner reviews and a smaller, lower robot (84 mm tall against 97 mm).
The Dreame D30 Ultra CE pulls harder (25000Pa versus 20000Pa), runs longer (230 minutes on a charge against 200), carries a 3-year warranty instead of 1 year and usually costs less. Both map with LiDAR, empty themselves and wash, dry and lift their mops at the dock. Low furniture and tight spaces favor the Roomba, while suction, runtime and a longer warranty point to the Dreame.
