## What reviewers found

### Narwal Flow

- Vacuum Wars (3.58 Vacuum Wars stars): Measured 1.88 kPa suction, 83% sand removal, 89% flattened pet hair pickup and 0% hair tangle. Combined mopping score was 268 against a 184 average, obstacle avoidance 18 of 24 and estimated coverage 2,068 sq ft per charge. [Source](https://vacuumwars.com/narwal-flow-review/)
- TechRadar: Called the cleaning superb, especially on carpet, and hot water mopping excellent. Noise was 58 dB in quiet mode and 76 dB at top suction. It pushed a chair, failed to enter a room and once reported 0.0 square meters cleaned. Subscores: Value 4/5, Design 4.5/5, Performance 3.5/5, App 3.5/5. [Source](https://www.techradar.com/home/robot-vacuums/narwal-flow-review)
- Tom's Guide: Pickup was 83% overall on tile and 77% on carpet, with 70% to 75% hair pickup. Noise ranged from 49 to 74 dB depending on floor and power. Faults were a tricky app, random cleaning incidents and so so edge vacuuming. [Source](https://www.tomsguide.com/home/smart-home/narwal-flow-robot-vacuum-and-mop-review)

### 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/)
