## What reviewers found

### Narwal Flow 2

- Vacuum Wars (3.88/5): Lab tests found 84% sand removal from carpet, 88% flattened pet hair pickup, 0% hair wrap and 20 of 24 obstacles avoided; a retest after a firmware update put mopping well above average, but the studio vacuum and mop run lasted only 38 minutes. [Source](https://vacuumwars.com/narwal-flow-2-review/)
- Tom's Guide: Picked up 100% of kitty litter on both floors, 100% of pet hair on hardwood and 80% on carpet, but only 30% and 20% of cereal; reviewer said edges and corners need manual cleaning and it does not live up to its price.

- 9to5Google: Cleaned about 1,300 sq ft with back to back vacuum and mop passes without stopping to recharge; reviewer rated it roughly equal to the Roborock Saros 20 but noted the taller body. [Source](https://9to5google.com/2026/06/24/narwal-flow-2-review/)

### 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.

- 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)
