Our Verdict
Roborock S8 Pro Ultra
Dreame X50 Ultra
The Roborock S8 Pro Ultra is a better robot vacuum than the Dreame X50 Ultra because it delivers better cleaning performance on hard floors and carpets. If you have a pet, the Roborock's pet hair cleaning performance is excellent, far better than the Dreame's. But obstacle avoidance, low height clearance, and threshold clearance are much better on the Dreame, should these factors be more important to you.
