## What reviewers found

### Roborock Qrevo S Pro

- Vacuum Wars (2.70 Vacuum Wars stars): Strong mopping (39.4 vs 31.1 average) and 81% carpet deep clean, but 43% pet hair pickup, 62% long hair wrap and only 5 of 24 obstacles avoided. Estimated 1,495 sq ft per charge. [Source](https://vacuumwars.com/roborock-qrevo-s-pro-review/)
- T3: UK review measured 64 dB vacuuming, 52 dB mopping and 70 dB emptying. It switched well between carpet and hard floor, but missed some debris on textured rugs and handled large dried cereal poorly.

- 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)
