One of the best mopping robots tested, with strong measured suction, zero hair tangles and a dock that washes and dries the track mop. Testers at TechRadar and Tom's Guide found the software and navigation quirky. Skip it if you want a simple app, and compare it against the Flow 2 since the Narwal store showed the Flow out of stock.

A mop first robot with firm pressure and hot air drying, now far below its launch price. nextpit measured 96% sand pickup on carpet, but Vacuum Wars scored its obstacle avoidance poorly. There is no dock emptying, so you change a small bag in the robot.

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
- 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
- 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
Narwal Freo X Ultra
- Vacuum Wars (2.26 Vacuum Wars stars): Measured 1.86 kPa suction, 16 CFM airflow and 76% pet hair pickup. Estimated 1,103 sq ft per charge. Obstacle avoidance scored 1.22 stars. Source
- TechRadar (Performance 4.5/5): Measured 53 dB. Picked up Cheerios in one pass and handled a soy sauce spill in about two. The app could not split an open plan floor into rooms. Source
- nextpit: Picked up 99% of oat flakes and 98% of sand on tile and 96% of sand on carpet. Ran about 2 hours before returning at 20%. A dust bag burst after six hours of use. Source
