## What reviewers found

### Ecovacs Deebot X12S OmniCyclone

- BGR: Picked up debris well on carpet and hard floors and mopping was strong, though some stubborn stains stayed; first map merged rooms and needed about 15 minutes of editing, and the dock full alert was easy to miss. [Source](https://www.bgr.com/2251627/ecovacs-deebot-x12s-omnicyclone-review/)
- The AU Review (5/5): Three weeks in an apartment with a shedding dog; cleaned hardwood and light rugs thoroughly in under an hour, but got stuck on a sock once. [Source](https://www.theaureview.com/?p=311464)

### 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/)
