- Our score: not scored yet
- Price: $1,500 (checked Oct 31, 2026)
- Status: on sale
- Best for: hard floor homes that mop often and have pets
- Skip if: you want a simple, glitch free app
- HTML version: https://robotsforthat.com/robot/narwal-flow/

## Verdict

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.
