Both Roborock and Roomba are quality machines in their own right, but Roomba technology generally has stronger performance when it comes to suction and cleaning power. Roborock models, on the other hand, have stronger navigation. The Roborock 2-in-1 models have both vacuum and mop features; the Roomba, however, has a self-emptying feature, which the Roborock does not. Users who have tested both machines claim that the Roborock has better brushes than the Roomba. Roborock is also quieter during the vacuuming process.
