## What reviewers found

### Narwal Freo 20 Edge

- Gadget Flow: Three week home test with a shedding dog. Cleared dried coffee and ketchup on the first pass, reached true corners and kept the brush nearly free of hair. Slowed down on a rug. [Source](https://thegadgetflow.com/blog/narwal-freo-20-edge-review/amp/)
- EFTM: Measured 49 dB quiet, 52 dB standard, 54 dB strong and 60 dB max. Avoided 3 of 4 obstacles but not fake pet waste, stopped at a drop and got stuck on door tracks. Called the mop its standout feature. [Source](https://eftm.com/2026/10/review-the-narwal-freo-20-edge-an-all-rounder-robot-vac-with-all-the-features-you-need-281793/amp)

### 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)
