Its HydroJet roller mop is the signature feature and beats Ecovacs on stain-lifting, and the app is best-in-class. Suction tops out at 8,000 Pa, the main tradeoff against the top of the list. On mostly hard floors that's a non-issue; deep carpet owners should step up to the Qrevo Curv or X50 Ultra. Eufy's past privacy reputation also weighs on some buyers.

Strengths
  • HydroJet roller mop with 1,500 RPM pressure-wash mopping — stronger than Ecovacs's roller in stain tests
  • 8,000 Pa suction — lowest on this list but well-engineered airflow keeps pickup competitive on hard floors
  • 3D ToF navigation plus RGB camera for obstacle avoidance
Watch-outs
  • 8,000 Pa suction trails the 18,000-22,000 Pa tier from Roborock/Dreame/Ecovacs — less effective on deep carpet
  • Eufy's 2022 privacy incident (cloud-uploaded snapshots despite local-only marketing) is a trust issue some users still hold
  • Dock is the largest of the five — roughly the footprint of a small trash can
Roborock Saros Z70
Ranked #5 in Best Premium Robot Vacuums
Roborock Saros Z70
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
