Quick verdict
Roborock Qrevo Curv
Roborock Saros Z70
Roborock Qrevo Curv scores higher with a 4.2/5 average across professional reviews from 3 sources.

The Roborock Qrevo Curv is the current best overall premium robot vac — TechRadar 4.5/5, PCMag and Tom's Guide both 4/5. It delivers 90% of the Saros Z70's core cleaning for roughly half the price. The AdaptiLift chassis is uniquely useful for homes with door thresholds, and the Omni dock is the full-feature version. If you're shopping premium robot vacs and don't specifically want the novelty arm, this is the pick.
Strengths
- +AdaptiLift chassis physically rises to clear 4cm thresholds — uniquely good for multi-room layouts with raised door sills
- +18,500 Pa suction with DuoDivide dual-brush system that resists hair tangling
- +Reactive AI 2.0 identifies 73 object types — excellent obstacle avoidance including socks, cables, pet waste
- +Curved Omni dock with hot-water mop wash up to 80°C, auto-drying, detergent dispensing, water refill, self-empty
- +StarSight 2.0 dual-eye vision system plus LiDAR for accurate mapping
Watch-outs
- −Still ~$1,500-1,700 MSRP — premium tier pricing with no robot arm for the spend
- −Mop lift is 10mm, not the full 22mm of the Dreame X50 Ultra — sometimes edges of high pile carpets still get touched
- −App occasionally drops devices during firmware updates

The Roborock Saros Z70 is the first robot vacuum with a real robotic arm, and it's a technology showcase rather than a mature product. PCMag 3/5 and TechRadar 3.5/5 both agree the core cleaning is excellent but the arm is a $1,000+ novelty over the Qrevo Curv. Buy it if you want to be first on your block with a robot-armed vac; otherwise save ~$1,500 and get the Qrevo Curv.
Strengths
- +OmniGrip robotic arm is a genuine first — it can pick up socks, cables, and small toys up to 300g and move them aside before vacuuming
- +22,000 Pa suction with dual spinning mop pads that lift when transitioning onto carpet
- +StarSight 2.0 dual-eye vision + LiDAR navigation handles complex layouts with strong obstacle avoidance
- +Reactive AI 3.0 can identify 108 object types including pet waste
- +Full Omni dock: self-empty, hot-water mop wash with auto-drying, detergent dispensing, water refill
Watch-outs
- −At ~$2,600 it's the most expensive robot vac ever sold — reviewers consistently flag that 95% of its value is in standard Roborock features, not the novelty arm
- −Robotic arm is slow and gimmicky in practice — TechRadar 3.5/5 and PCMag 3/5 both note it's a proof-of-concept more than a mature feature
- −Arm can't actually tidy a room in any meaningful way — it picks one item at a time and places it at a designated drop zone
