Narwal Flow
Excellent mopping track mop robot, now the step below the Flow 2
Researched by Riley Hart · updated Oct 30, 2026
Is the Narwal Flow worth it? One of the best mopping robots tested, with strong measured suction, zero hair tangles and a dock that washes and dries the track mop. It costs $1,500 as of Oct 31, 2026, and 3 independent reviewers tested it.
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.
Best for: hard floor homes that mop often and have pets. Skip if: you want a simple, glitch free app.

- Vacuum Wars · 3.58 Vacuum Wars stars
- 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.
- TechRadar
- 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.
