Dreame X50 Ultra vs Roborock Saros Z70

The Dreame X50 Ultra is a better robot vacuum than the  Roborock Saros Z70. The Dreame can clear high thresholds just as well as the Roborock can, and can get under furniture almost as low as the Roborock does. In addition, the Dreame's obstacle avoidance system performs even better than Roborock's. The Roborock does a better job cleaning hard floors, stains, and pet hair, but the Dreame performs better on carpet. With the Roborock Saros Z70 costing so much more than the Dreame X50 Ultra due to its mediocre robotic arm, you will probably find the performance tradeoffs worth the much lower price.
