## What reviewers found

### 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/)

### Roborock S8 MaxV Ultra

- TechRadar: Strong vacuuming and effective mopping on coffee and dried honey, fast accurate mapping. It got stuck on cables repeatedly, tried to vacuum a sock, and the extending side brush and voice assistant were unreliable. Subscores: Value 3.5/5, Design 4.5/5, Performance 4/5. [Source](https://www.techradar.com/home/robot-vacuums/roborock-s8-maxv-ultra-robot-vacuum-review)
- Vacuum Wars: Measured 0.18 kPa max suction and 13 CFM airflow, 1.41 min per 1% battery and 0.62 m² per min navigation. Handled dried coffee and grape juice stains with minimal streaks, and its feature score was the highest Vacuum Wars had recorded at the time.
