Ecovacs X9 Pro Omni vs Curv 2 Flow: The Mopping King Meets Roborock's Roller Challenger

Cleaning Performance

The Curv 2 Flow leads on raw suction — 20,000Pa vs 16,600Pa. That’s a 20% advantage that shows up clearly on carpet, where the Roborock pulls more embedded debris from medium and thick pile. Vacuum Wars confirmed 87% carpet deep-clean and 0% hair tangle for the Curv 2 Flow. We explain what these scores mean and how they’re measured in our how we test methodology.

The X9 Pro Omni compensates with the highest sealed suction among 2025 flagships at 2.76 kPa, meaning its airflow design extracts more per Pascal of suction than less efficient motors. It also scored 93% on pet hair pickup — one of the best numbers in the category.

On hard floors, the X9 Pro Omni’s OZMO Roller makes the comparison unfair — it simultaneously vacuums and scrubs in one pass. The Curv 2 Flow does the same with SpiraFlow, but the roller’s weak stain removal (25 pts at VW) means the vacuum is doing most of the work.

Winner: Roborock Qrevo Curv 2 Flow — Higher suction and better carpet performance. The X9 Pro Omni’s sealed suction is efficient, but 3,400Pa less raw power shows on thick carpet.

Navigation & Obstacle Avoidance

The X9 Pro Omni uses dToF LiDAR, RGBD sensor, and TruEdge 3D detection at 3.86 inches tall. It navigates with precision and fits under most standard furniture.

The Curv 2 Flow stands at 4.7 inches with PreciSense LiDAR, structured light, and an RGB camera. It recognizes 200+ object types — a broader library — but the height penalty means it misses under-furniture spaces the X9 Pro Omni cleans routinely.

The X9 Pro Omni struggles with thin unsecured rugs lacking rubber backing — they bunch up under the roller. The Curv 2 Flow’s water-blocking carpet guard and 15mm lift handle carpet transitions more gracefully.

Winner: Ecovacs Deebot X9 Pro Omni — Slimmer profile (0.84 inches less) accesses more of the home. The rug issue is a known quirk but doesn’t affect most homes.

Mopping

The OZMO Roller’s 4.95/5 mopping score at Vacuum Wars is the highest ever recorded. It applies 3,700Pa of mopping pressure at 220 RPM with instant self-wash — dirty water is extracted continuously, never dragged back across clean surfaces. On every stain type tested, the X9 Pro Omni set category records.

The Curv 2 Flow’s SpiraFlow roller scored 25 points on dried stains. Category average: 112 points. Despite similar RPM (220) and a continuous self-cleaning mechanism, the SpiraFlow doesn’t dissolve or extract dried stains with anywhere near the OZMO Roller’s effectiveness.

Both robots self-clean their rollers during operation. The performance difference appears to stem from the OZMO Roller’s higher mopping pressure (3,700Pa vs 15N force) and its more aggressive water extraction design.

Winner: Ecovacs Deebot X9 Pro Omni — The greatest mopping system ever tested vs the greatest mopping disappointment of 2026. This category isn’t competitive.

Dock & Maintenance

Battery life overwhelmingly favors the Curv 2 Flow: 272 minutes vs the X9 Pro Omni’s real-world 115-158 minutes. That’s nearly double the effective runtime. For large homes, the Curv 2 Flow finishes in one continuous run while the X9 Pro Omni may need mid-clean recharges — and a recharge stop isn’t just lost minutes, it can stretch a scheduled morning clean deep into the afternoon. Households that run the robot in a fixed window while everyone is out will feel those 115-158 real-world minutes more than the spec sheet suggests.

The X9 Pro Omni’s dock auto-empties with a 150-day capacity — one of the most hands-free intervals available. The Curv 2 Flow uses sealed dust bags and smart dirt re-wash detection.

Both docks wash mops with hot water and dry with heated air. The X9 Pro Omni’s dock drying cycle is loud at approximately 72 dB — worth noting if the dock lives in a living area.

Winner: Roborock Qrevo Curv 2 Flow — Nearly double the battery life and quieter dock operation. The X9 Pro Omni’s 150-day auto-empty is impressive but can’t offset the runtime gap.

Smart Features & App

The X9 Pro Omni supports Matter — native integration with Apple Home, Google Home, and Alexa without cloud relay. In practice that means the robot can join Apple Home scenes and automations directly, rather than depending on a manufacturer cloud account staying online and supported.

The Curv 2 Flow supports Alexa and Google Home but not Matter. Both apps offer multi-floor mapping, room settings, and scheduling. The Roborock app has a slightly larger community; the Ecovacs app is feature-complete but occasionally criticized for stability.

Winner: Ecovacs Deebot X9 Pro Omni — Matter compatibility is a meaningful advantage, especially for Apple households.

Value & Price

At $849 vs $1,399, the Curv 2 Flow costs $550 less. For carpet-heavy homes where vacuuming power and battery life matter most, the Curv 2 Flow is the smarter purchase — 20,000Pa suction, 272-minute battery, and Roborock’s ecosystem for $550 less.

For hard-floor-dominant homes where mopping is the primary job, the X9 Pro Omni’s OZMO Roller is irreplaceable. No robot at any price mops as well. The $550 premium buys the best mopping system available, Matter support, and 93% pet hair pickup.

The verdict depends entirely on your floors. Carpet-first buyers save $550 with the Curv 2 Flow and get a better vacuum. Hard-floor-first buyers invest $550 more in the X9 Pro Omni and get mopping that no competitor can touch.

There’s also a third path hiding in Roborock’s own catalog: the Qrevo CurvX sells at the same $849 with 22,000Pa and conventional dual spinning pads. If the SpiraFlow’s stain numbers put you off but the X9 Pro’s price does too, the CurvX sidesteps the roller question entirely.

Winner: Roborock Qrevo Curv 2 Flow — $550 savings with better suction and far more battery. The X9 Pro Omni’s mopping justifies its premium for hard-floor homes, but the per-dollar value favors the Roborock for general-purpose cleaning.
