Higher ratedRanked #3 in Best Premium Robot Vacuums

Roborock Qrevo Curv

4.2

5 sources$800as of Aug 2

For most premium buyers the Roborock Qrevo Curv is the one to get: TechRadar 4.5/5, PCMag and Tom's Guide both 4/5. It covers 90% of the Saros Z70's core cleaning for roughly half the price. The AdaptiLift chassis is genuinely useful in homes with door thresholds, and the Omni dock is the full-feature version. Unless you 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

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

Ranked #5 in Best Premium Robot Vacuums

Roborock Saros Z70

3.5

3 sources$1,699.99as of Aug 2

A real robotic arm makes the Roborock Saros Z70 the first of its kind, and it reads more like a technology showcase than a mature product. PCMag (3/5) and TechRadar (3.5/5) agree the core cleaning is excellent while the arm amounts to a $1,000+ novelty over the Qrevo Curv. Buy it 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

Watch-outs

— At $1,699.99 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
