Unlike the Roborock model, the Dreame version appears to be more durable, with a thicker arm and sturdy arms that can potentially lift heavier objects. The Roborock arm can lift objects weighing up to 300 grams, for which Dreame did not specify a weight limit for his prototype.
Although the Dreame robot did not demonstrate how to pick up the objects, the arm was extended and retracted repeatedly. Apparently, the device is built on a similar platform to the Dreame X50, equipped with “legs” for climbing stairs.
