Which is the better pick? We compared ratings from professional reviewers to help you decide.
Quick verdict
Eufy Omni S1 Pro
Roborock Saros Z70
Eufy Omni S1 Pro scores higher with a 4.2/5 average across professional reviews from 2 sources.
The Eufy Omni S1 Pro is a solid middle-tier premium pick — TechRadar 4/5, CNET 8.5/10. The HydroJet roller mop is its signature feature (beats Ecovacs on stain-lifting), and the app is best-in-class. The lower 8,000 Pa suction is the main tradeoff versus the top of the list; if your home is mostly hard floors it's a non-issue, but deep carpet owners should step up to Qrevo Curv or X50 Ultra. Eufy's past privacy reputation is also a factor for 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
- +Auto-refill with clean water and hot-air mop drying; detergent dispensing
- +Best-in-class app with genuinely useful room-by-room cleaning controls
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
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
