2026 verdict
Reliability against raw suction and coverage: the iRobot Roomba 415X takes the overall win over the Dreame D30 Ultra thanks to a higher owner rating.
The Dreame D30 Ultra is not far behind, and it actually out-suctions the iRobot Roomba 415X on paper, runs longer per charge (230 minutes against 200), ships with a considerably longer warranty, and adds a Home Assistant integration that the iRobot Roomba 415X does not confirm. Both are self-emptying vacuum-and-mop combos with LiDAR navigation and a dock that washes and dries the mop pads automatically. Buyers who weight owner ratings heavily should pick the iRobot Roomba 415X; anyone chasing the strongest suction figure, a longer runtime, a longer warranty or Home Assistant support should choose the Dreame D30 Ultra.
