The Dreame D30 Ultra CE wins this robot vacuum comparison on the things that decide daily use: LiDAR mapping that works in the dark, a longer run per charge, a larger water tank, a much higher owner rating and a three-year warranty against one year. The iRobot Roomba Combo 10 Max robot + AutoWash dock promises more on paper, with self-emptying, mop washing, drying and refilling, plus broad integrations that reach Apple HomeKit, Samsung SmartThings and Matter. In practice its own review data shows a low average rating, with owners reporting jobs that stop partway and camera-based navigation that needs the lights on, and it typically costs more. Unless Apple Home or SmartThings compatibility is essential, the Dreame D30 Ultra CE is the far safer buy here.
