## What reviewers found

### Ecovacs Deebot T90 Pro Omni

- Vacuum Wars (4.00/5): Measured 21 CFM airflow, 81% carpet sand removal, 100% pet hair pickup, 0% hair wrap, 23 of 24 obstacles avoided, about 1,372 sq ft per charge and a 34.6 combined mopping score versus a 20.3 average; it cleared 32 mm against a 40 mm claim. [Source](https://vacuumwars.com/ecovacs-deebot-t90-pro-omni-review/)
- TechRadar: Tested in Australia. Mapping took six sessions, auto mode mopped carpeted bedrooms, pet hair was left behind and tangled in the brush, and wood floors were left streaky. The reviewer did not recommend it. [Source](https://techradar.com/home/robot-vacuums/for-a-brand-that-made-robot-vacuums-accessible-my-faith-in-ecovacs-is-shaken-after-using-the-deebot-t90-pro-omni)
- Notebookcheck: Very good mopping and nearly perfect medium pile carpet pickup at max suction; it touched thin chair legs and missed a small toy brick, and corner cleaning was weaker. Measured about 58 dB on carpet at standard settings. [Source](https://www.notebookcheck.net/Mid-range-robot-vacuum-puts-flagships-to-shame-Ecovacs-Deebot-T90-Pro-Omni-review.1249595.0.html)

- Tom's Guide: Picked up 100% of cereal and kitty litter on carpet and 70% of pet hair on carpet, but mopping left floors streaky and patchy and the pads fell off once crossing a cable. [Source](https://www.tomsguide.com/home/home-appliances/roborock-saros-20-review)
