## 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.

- 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 Qrevo Curv 2 Flow

- CyberShack (8.7/10): Excellent hard floor vacuuming at 91% to 95% and good mopping close to skirting, above average on short and medium pile carpet, but weak on carpet pet hair and no edge or corner cleaning on carpet. Measured 100 to 125 minutes of real runtime. [Source](https://cybershack.com.au/cleaning/roborock-qrevo-curv-2-flow-another-great-robovac-roller-mop-review)
- Gizmodo: Called the roller mop the most powerful robot mop it had tested where it can reach, with good hair and sand pickup, but edge gaps of around 8 inches at times, a swallowed USB C cord and sock, and limited battery for large homes. [Source](https://gizmodo.com/roborock-qrevo-curv-2-flow-review-ultimate-robot-mop-if-you-dont-have-corners-or-walls-2000745723)
- Vacuum Wars (3.64/5): Strong vacuum with 87% carpet sand removal and 0% hair tangles, but a combined mopping score of 13.7 against a 22.75 category average and 16 of 24 obstacles avoided. Headline verdict: strong vacuum, disappointing mopping. [Source](https://vacuumwars.com/roborock-qrevo-curv-2-flow-review)
