Our Verdict

Roborock S8 MaxV Ultra

Dreame X50 Ultra

The Roborock S8 MaxV Ultra is slightly better than the Dreame X50 Ultra overall because it delivers better cleaning performance than the Dreame. It performs a lot better on hard floors and pet hair and a little better on carpets. But the Dreame offers features the Roborock can't match, like a retractable LIDAR sensor for better clearance under low furniture and a much better threshold clearance system.
