## What reviewers found

### Roborock Qrevo CurvX

- TechGearLab (85/100): Ranked first of 23 robots. Hard floor and mopping 9.3, carpet 8.4 with about 79% of debris cleaned, but only 52% of pet hair. Avoided 88% of obstacles. Measured 56.3 dB vacuuming. [Source](https://www.techgearlab.com/reviews/smart-home/robot-vacuum/roborock-qrevo-curvx)
- Vacuum Wars (3.69 Vacuum Wars stars): Long term test in a 750 sq ft home with a dog. Mopping was strong with vacuum then mop runs and nothing wrapped the brush, but the 260 ml bin clogged almost daily and it often tried to climb objects and needed help. [Source](https://vacuumwars.com/roborock-qrevo-curvx-after-3-months/)
- Popular Mechanics: Picked up flour, corn flakes, rice and pet hair on several floors and reached under furniture better than most robots tested. First mapping took about 30 minutes. [Source](https://tech.yahoo.com/home/articles/roborock-qrevo-curvx-slim-frame-202959647.html)

[Source](https://vacuumwars.com/roborock-saros-20-review/)
- CGMagazine (8.5/10): Performed strongly on pet hair, sand and fine dust on carpet and hard floors and fit under low furniture; reviewer flagged middling battery life, a small bin and trouble with loose cables. [Source](https://www.cgmagonline.com/review/hardware/roborock-saros-20-robot-vacuum/)
- 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)
