## 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)

### eufy Omni E35

- TechRadar: Max power with two passes left carpet flawless and one low power pass cleared oats on carpet. Dried ketchup needed 100% water flow and a second pass. Measured 60 to 67 dB while cleaning. Subscores of 4.5/5 for design, performance and app. [Source](https://techradar.com/home/robot-vacuums/eufy-omni-e35-review)
- Gizmodo (4): Vacuumed and mopped a 750 sq ft apartment in about an hour with 64% battery left, faster than a Roborock Qrevo 2 Pro. Mopping was streak free, but it bumped walls and spun in reverse circles three times. [Source](https://gizmodo.com/eufy-omni-e35-review-robot-vacuum-2000819785)
- T3: Rated mopping excellent on sticky stains and said the roller reaches skirting boards. Thick rugs were still a challenge, and a few water drops appeared around the dock. Tested on beta app software. [Source](https://www.t3.com/home-living/vacuum-cleaners/eufy-robot-vacuum-omni-e35-review-i-love-the-form-factor-of-this-compact-but-clever-robovac)
