## What reviewers found

### Ecovacs DEEBOT T90S PRO OMNI

- Notebookcheck: Very good mopping and obstacle detection; cleaned about 50 square meters in 80 min on default settings and ended at 63% battery; carpet cleaning good but not perfect; struggles with corners and avoids narrow spaces.

- inside digital: Sponsored review: picked up 92% of oats on tile, 90% on carpet and 75% of sand on carpet; 63% battery left after 30 min at full power; strong mopping and self flushing dock, but weak corner suction, hair wrap and collisions with chair and table legs.

### 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/)
