Quick Verdict
The Ecovacs X9 Pro Omni is the best mopping robot ever tested (4.95/5 Vacuum Wars score) with its OZMO Roller instant self-wash system. The Dreame L40 Ultra Gen 2 has nearly double the suction (25,000Pa vs 16,600Pa) and costs less than half the price. Choose the X9 Pro for hard floors and mopping; choose the L40 Gen 2 for carpet-heavy homes and value.

Cleaning Performance
These robots take opposite approaches to cleaning. The L40 Gen 2 leads with raw power: 25,000Pa suction — 50% more than the X9 Pro Omni’s 16,600Pa. On carpet, this translates to meaningfully better embedded debris removal.
The X9 Pro Omni counters with the best mopping system ever put in a robot vacuum. Its OZMO Roller spins at 220 RPM with 3,700Pa downward pressure while continuously self-washing — the mop is always clean as it crosses your floor. It scored 4.95/5 in Vacuum Wars mopping tests, a record that no other robot has approached.
For vacuuming, the L40 Gen 2 is superior. Its 25,000Pa suction and TriCut hair-cutting brush handle carpet, pet hair, and embedded dirt more effectively. The X9 Pro Omni achieves the highest sealed suction measured among 2025 flagships (2.76 kPa), but its 16,600Pa rated suction still trails the L40 Gen 2 on carpet.
For mopping, the X9 Pro Omni is in a different league. The L40 Gen 2’s dual spinning pads are adequate for maintenance mopping but can’t match a roller that self-cleans during operation.
Winner: Depends on your floors — L40 Gen 2 for carpet; X9 Pro Omni for hard floors.
Navigation & Obstacle Avoidance
The X9 Pro Omni uses dToF LiDAR, RGBD sensor, and TruEdge 3D detection. Its obstacle avoidance is mature and effective, handling most household objects reliably. It achieves 93% pet hair pickup rate, suggesting precise path planning.
The L40 Gen 2 uses LiDAR, 3D structured light, and an RGB camera. Its AI obstacle avoidance is solid for a mid-range robot, detecting common objects like shoes, cables, and pet waste.
Neither robot has the ProLeap-style obstacle climbing of Dreame’s premium models. The X9 Pro Omni is slightly taller at 3.86 inches versus the L40 Gen 2’s 3.8 inches — a negligible difference.
Winner: Ecovacs X9 Pro Omni — More refined sensor fusion and higher obstacle avoidance reliability.
Dock & Maintenance
The X9 Pro Omni’s dock auto-empties with a 150-day capacity, washes with hot water, heat-dries, and auto-refills water. The OZMO Roller’s self-cleaning mechanism means the mop pad stays cleaner during operation than any spinning pad system.
The L40 Gen 2’s dock auto-empties (100 days), washes mops at 149°F, hot-air dries, auto-refills water, and adds auto solution refill. The auto solution dispenser is a genuine convenience advantage.
The X9 Pro Omni’s 150-day empty capacity is the longest here, meaning fewer bag changes. The L40 Gen 2’s auto solution refill means one less thing to manually manage.
Winner: Tie — X9 Pro has longer empty capacity and self-cleaning roller; L40 Gen 2 has auto solution refill.
Battery & Runtime
The L40 Gen 2 runs for approximately 194 minutes with best-in-class efficiency. The X9 Pro Omni claims 200 minutes but real-world testing shows 115-158 minutes — significantly shorter due to the OZMO Roller’s power draw.
For larger homes, the L40 Gen 2’s consistent battery performance is a notable advantage. The X9 Pro Omni may need a mid-clean recharge in homes over 1,500 square feet.
Winner: Dreame L40 Ultra Gen 2 — Significantly better real-world battery life.
Value & Price
The L40 Gen 2 at $499-649 (typically ~$549) versus the X9 Pro Omni at $1,299-1,499 (typically ~$1,399). The X9 Pro Omni costs roughly 2.5x more.
The L40 Gen 2 delivers higher suction, longer battery life, and a more feature-rich dock at a fraction of the price. The X9 Pro Omni’s premium buys you the best mopping system in any robot vacuum and Matter/Apple Home compatibility.
If your home is primarily hard floors and you want the absolute best mopping, the X9 Pro Omni justifies its price. For mixed flooring or carpet-heavy homes, the L40 Gen 2 is the dramatically better value.
Winner: Dreame L40 Ultra Gen 2 — Delivers more cleaning capability per dollar for most home types.

Frequently Asked Questions
Which is better for hard floors — L40 Gen 2 or X9 Pro Omni?
The X9 Pro Omni is significantly better for hard floors thanks to its OZMO Roller, which scored 4.95/5 in mopping tests — the highest ever. Its roller mop instantly self-washes during cleaning, maintaining clean contact at all times. The L40 Gen 2's dual spinning pads are competent but can't match the OZMO Roller's effectiveness.
Which is better for carpet — L40 Gen 2 or X9 Pro Omni?
The L40 Gen 2 with 25,000Pa suction significantly outperforms the X9 Pro Omni's 16,600Pa on carpet. For homes with significant carpet coverage, the L40 Gen 2 is the clear choice.
Is the Ecovacs X9 Pro Omni worth 2-3x the price of the L40 Gen 2?
Only if mopping is your top priority. The X9 Pro Omni's OZMO Roller is genuinely transformative for hard floor cleaning. For general vacuuming and mixed flooring, the L40 Gen 2 delivers more cleaning power per dollar.
Do both robots work with Apple Home?
The Ecovacs X9 Pro Omni is Matter-compatible and works with Apple Home, Google Home, and Alexa. The Dreame L40 Gen 2 supports Alexa and Google Home but does not support Apple Home natively.
