## What reviewers found

### Roborock Saros 10R

- BGR: Called it Roborock's best model at launch. It fit under sofas and beds, had about 57% battery left after about 80 minutes of vacuuming and mopping, and needed tank service every four to six cleanings. It tangled in cables until a no go zone was set. [Source](https://bgr.com/reviews/roborock-saros-10r-review/)
- TechRadar: Noise measured 62 dB at source and 55 dB at 10 feet. Oats were cleared but flour stayed in floor seams on Max and Max+. It cleaned a syrup, soy sauce and milk spill in one pass on low water and mapped five areas in about 5 min. It rode over a 1 inch dog bone until Pet mode was turned on, and the dust bag filled in about three weeks. [Source](https://www.techradar.com/home/robot-vacuums/roborock-saros-10r-robot-vacuum-review)
- Vacuum Wars (3.64 Vacuum Wars stars): Picked up 80% of embedded sand from medium pile carpet against a 75% average and 92% of flattened pet hair, with 0% hair tangling. Avoided 24 of 24 obstacles. Cleared 20 mm and 26 mm boards but failed a single 36 mm threshold. Estimated about 1,389 sq ft per charge. The onboard bin is 270 ml. [Source](https://vacuumwars.com/roborock-saros-10r-review)

### Roborock Saros 20

- Vacuum Wars (3.81/5): Lab tests found 89% sand removal from carpet, 88% flattened pet hair pickup, 0% hair wrap, 17 of 24 obstacles avoided, a record 57 mm threshold climb and an above average combined mopping score; battery coverage was slightly below average at about 1,038 sq ft per charge. [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)
