## What reviewers found

### Dreame L40 Ultra Gen 2

- Vacuum Wars (3.11 Vacuum Wars stars): Dried stain score 144 (108 average), 90% carpet sand removal, but 69% pet hair pickup, 67% hair wrap and only 2 of 24 obstacles avoided. Estimated about 1,290 sq ft per charge. [Source](https://vacuumwars.com/dreame-l40-ultra-gen-2-review/)
- Vacuum Chef: Measured 11.5 CFM airflow, 90% coffee, 60% sand and 98% cat litter pickup, 73 dB at max and a 30% obstacle avoidance score against a 66% average. Called it a rebalancing rather than an upgrade. [Source](https://vacuumchef.com/?p=12466)

### Ecovacs Deebot X9 Pro Omni

- Vacuum Wars: Measured 2.76 kPa suction and 27 CFM airflow, 93% pet hair pickup, 0% hair wrap, 158 of 184 on dried stains and 89% carpet deep clean. Coverage was 876 sq ft per charge against a 1,015 sq ft average. [Source](https://vacuumwars.com/ecovacs-deebot-x9-pro-omni-review/)
- MacRumors: Three months of testing. Long hair did not tangle the brush, mopping and navigation beat the X8 Pro Omni, and Siri control through Matter worked. Thin rugs caused frequent tangles and vacuuming was loud. About 1,000 sq ft per charge. [Source](https://www.macrumors.com/review/ecovacs-x9-pro-omni-robot-vacuum/)
- BGR (9/10): Called the roller mop the best robot mop available and vacuuming very good. Mapping was error prone and needed about 20 minutes of fixes, and tanks are no longer see through. [Source](https://bgr.com/reviews/ecovacs-deebot-x9-pro-omni-review-the-best-you-can-get-for-now/)
