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, where Dreame did not specify a weight limit for its prototype.
Although the Dreame robot did not demonstrate how to pick up objects, the arm extended and retracted repeatedly. Apparently, the device is built on a platform similar to the Dreame X50, which is equipped with “legs” for climbing stairs.
