Roborock Qrevo CurvX vs Ecovacs X9 Pro Omni: Upper-Mid vs Premium

Cleaning Performance

The Roborock Qrevo CurvX boasts 22,000Pa of suction — the highest in this comparison and one of the highest available in any consumer robot vacuum. The Ecovacs X9 Pro Omni specs at 16,600Pa but measured the highest sealed suction (2.76 kPa) among 2025 flagships, meaning its actual cleaning power is closer than the Pa gap suggests.

On carpet, the CurvX’s raw suction pulls embedded debris effectively, though its ultra-slim 3.14-inch chassis can limit brush engagement on thicker rugs — occasionally requiring multiple passes. The X9 Pro Omni handles carpet reliably with a 93% pet hair pickup rate.

The CurvX features a DuoDivide brush with a certified 0% hair tangle rate — the best in the industry. The Ecovacs ZeroTangle 3.0 is also excellent but slightly behind in independent testing.

On hard floors, the Ecovacs has an edge because its OZMO Roller vacuums and mops simultaneously in a single pass, leaving floors cleaner than sequential vacuum-then-mop approaches.

Winner: Tie — The CurvX has higher raw suction and zero hair tangle; the X9 Pro Omni has better airflow efficiency and simultaneous vacuum-mop cleaning.

Navigation & Obstacle Avoidance

The Ecovacs X9 Pro Omni uses dToF LiDAR combined with RGBD visual sensor and TruEdge 3D detection. It navigates accurately and avoids most obstacles reliably.

The Roborock Qrevo CurvX uses LiDAR with Reactive AI structured light — no RGB camera. This means no video monitoring, no AI pet waste detection, and less precise small-object avoidance. However, its AdaptiLift chassis lifts the robot up to 4cm over thresholds, solving a navigation problem the Ecovacs can’t address.

Both create accurate maps with multi-floor support. The CurvX’s ultra-slim profile lets it clean under furniture the X9 Pro Omni can’t reach at all — a practical navigation advantage in real homes.

Winner: Ecovacs X9 Pro Omni — Better obstacle detection sensors, though the CurvX’s under-furniture access and threshold climbing are valuable real-world advantages.

Mopping

The Ecovacs X9 Pro Omni’s OZMO Roller is the best mopping system available. At 220 RPM with 3,700Pa of pressure and instant self-washing, it scored the highest mopping marks ever recorded (4.95/5). It handles dried stains, grease, and tracked-in grime that no spinning pad system can match.

The Roborock Qrevo CurvX mops with dual spinning pads, 17mm auto-lift on carpet, and FlexiArm edge mopping. It offers warm-water mopping onboard, which is a nice touch. For daily maintenance — dust, light spills, footprints — it’s perfectly adequate.

But for serious hard-floor cleaning, the gap is enormous. The OZMO Roller’s continuous self-wash means it never spreads dirty water, while pad systems inherently do until the pads return to the dock for cleaning.

Winner: Ecovacs X9 Pro Omni — The OZMO Roller is in a different category of mopping performance.

Dock & Maintenance

The Roborock Qrevo CurvX’s Thermo+ Dock washes mops with 176°F hot water (among the hottest available), dries with 113°F warm air, auto-empties, auto-refills water, and features a detachable base for easier cleaning. The high water temperature provides genuine bacterial reduction.

The Ecovacs X9 Pro Omni’s Omni Station offers 150-day self-empty capacity, hot water wash, heat drying, and self-cleaning roller. The roller requires less maintenance than dual mop pads since it’s a single component.

The Ecovacs dock is loud during its drying cycle (~72 dB). The Roborock dock runs quieter.

Winner: Roborock Qrevo CurvX — 176°F hot water washing (the hottest available), quieter operation, and a detachable base for easier maintenance.

Smart Features & App

The Ecovacs X9 Pro Omni is Matter-compatible, working natively with Apple Home, Google Home, and Alexa without cloud bridges. This is a clear advantage for smart home ecosystems.

The Roborock app is polished with 3D mapping, furniture icons, and granular per-room settings. The CurvX supports Alexa and Google Home but not Matter/Apple Home natively.

Neither robot has RGB camera-based video monitoring — the CurvX has no camera at all, and the Ecovacs’ sensors don’t support live video feeds in the same way.

Winner: Ecovacs X9 Pro Omni — Matter compatibility for Apple Home is a significant smart home advantage.

Value & Price

The Roborock Qrevo CurvX at $799-$899 costs roughly $400-$600 less than the Ecovacs X9 Pro Omni at $1,299-$1,499. That’s a massive price gap.

For that $400-$600 less, the CurvX delivers higher suction (22,000Pa), an ultra-slim profile (3.14in), 0% hair tangle rate, threshold climbing, and hotter dock water (176°F). You give up the OZMO Roller mopping system, Matter smart home compatibility, and slightly better obstacle detection.

For most households, the Roborock Qrevo CurvX is the dramatically better value. The Ecovacs X9 Pro Omni is justified only if mopping quality is your absolute top priority or if Matter/Apple Home integration is essential.

Winner: Roborock Qrevo CurvX — Higher suction, slimmer profile, and comparable features at roughly half the price make it the clear value winner.
