What reviewers found
Narwal Flow 2
- CGMagazine (9/10): Praised mopping and obstacle avoidance in a 780 sq ft apartment, but the dock repeatedly showed false leak or overflow warnings. Source
- 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
Narwal Freo Z10 Ultra
- CGMagazine (9.5): Praised accurate LiDAR room detection, quick reaction to moving people, resistance to hair tangling and AI adjusted wash water temperature. Reported no significant faults beyond the premium price. Source
- TechRadar: Solid everyday vacuuming, but fine flour mix stayed after three passes. Great edge mopping and removed dried ketchup. Ran about 2.5 hours and measured about 60 dB. Smart mode skipped rooms and self emptying was unreliable. Subscores: Value 3.5/5, Design 4/5, Performance 3/5 in text (2.5/5 in table), App 3.5/5 in text (3/5 in table). Source
