The verdict
The Dreame X50 Ultra is the high-performance alternative to the Roborock Qrevo Curv — TechRadar 4.5/5 calls it out for the ProLeap chassis (6cm lift, beating Roborock's 4cm) and strongest suction-plus-extending-brush combo. App maturity is the weakest point versus Roborock. Pick this if you have thresholds higher than 4cm or want the best corner reach; otherwise the Qrevo Curv's app polish is slightly better.
Strengths
- +ProLeap chassis raises the entire body up to 6cm — highest threshold-clearing of any robot vac
