## What reviewers found

### Ecovacs DEEBOT T90S ULTRA OMNI

- Notebookcheck: Review of the closely related T90S Pro Omni (same 40,000 Pa rating and about 16 L/s airflow): very good mopping and obstacle detection, cleaned about 50 square meters in 80 min ending at 63% battery, good but not perfect carpet cleaning, struggles in corners and narrow spaces.

- inside digital: Sponsored review of the closely related T90S Pro Omni: picked up 92% of oats on tile, 90% on carpet and 75% of sand on carpet; strong mopping and self flushing dock, but weak corner suction, hair wrap on brushes 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/)
