Higher ratedRanked #4 in Best Premium Robot Vacuums

Eufy Omni S1 Pro

4.1

$799as of Apr 17

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

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

Ranked #5 in Best Premium Robot Vacuums

Roborock Saros Z70

3.5

$2,399as of Apr 17

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

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
