Ecovacs Deebot X8 Pro Omni

4.2

4 sources$549.99as of Aug 2

Mopping is the reason to buy the Ecovacs Deebot X8 Pro Omni. Its Ozmo Roller mops with fresh water continuously rather than dragging a wet pad around, a material improvement on the method everyone else uses. PCMag and TechRadar both give it 4.5/5; Tom's Guide 4/5. The tradeoff is a taller robot that has more trouble clearing low furniture. Choose it over the Roborock or Dreame if your floors are mostly hard surface and mopping is the killer feature for you.

Strengths

— Ozmo Roller mop is genuinely innovative — a continuously-rotating roller that self-cleans with fresh water constantly instead of dragging a wet pad
— 18,000 Pa suction with AIVI 3D 2.0 obstacle avoidance
— Yiko AI voice assistant works on-device — no internet required for basic commands

Watch-outs

— Roller mop height means it can't go under furniture with <11cm clearance — Qrevo Curv and Dreame X50 are slimmer
— Dock is physically larger than Roborock's — notable in tight laundry-room installs
— Ecovacs app has been slower to push firmware updates than Roborock over the past year

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
