Our take
Narwal Flow 2
Extended home testing praised mopping and hair handling, while other tests found missed debris and docking difficulty. The overall verdict remains mixed.
Positive floor finish in a three-month home trial.
App friction and conflicting pickup results.
Homes prioritising 31,000 pa suction.
Buyers who want a basic vacuum without mopping, advanced navigation or dock automation.
- 31,000 Pa suction — an advertised pressure figure, not a cleaning score.
- Next-generation track mopping
What reviewers found
Extended home use gave the Flow 2 a much warmer verdict than some controlled tests. Its best reports describe clean, streak-free floors and effective hair management; less positive testing found missed cereal, edge debris and docking frustrations. The app is another ownership consideration.
A strong longer-term mopping result
After three months, Vacuum Wars’ home reviewer praised the floor finish and found little residue or streaking. That was better than its earlier studio stain results. A firmware update occurred before home use, but the reviewer explicitly could not establish that it caused the improvement. We retain the disagreement instead of treating the later result as proof every unit is fixed.
[1]Everyday dirt and larger pieces differ
Tom’s Guide found ordinary dirt and cat litter straightforward, but cereal was pushed around, crushed or trapped near wheels. Corners and edges also needed attention. This gives useful context to the positive mopping reports: being good at daily floor film does not automatically mean reliable collection of every larger kitchen spill.
[2]A promising experience with heavy shedding
The Vacuum Wars household had a heavily shedding dog, yet reported no hair clogging, bin overfilling or brush tangles. Cable avoidance was also notably dependable, with only two interventions during the trial for other causes. This is valuable extended-use evidence, although it remains one household rather than a measured owner-wide success rate.
[1]The app and dock can interrupt the convenience
Vacuum Wars found important app settings hard to locate and a late drying-complete announcement irritating. Tom’s Guide reported difficulty finding the dock after a small move. Choose a stable station location and allow time to learn the controls; the cleaning hardware’s sophistication does not make every daily interaction equally polished.
[1][2]Who is most likely to appreciate it
Our reading is that the strongest case is frequent mopping and routine pet-hair management on accessible hard floors. Buyers paying primarily for flawless debris pickup or an especially simple app should weigh the less positive findings carefully. The reviewed experience is mixed enough that a blanket best-in-class claim would hide meaningful compromises.
[1][2]These sources concern Flow 2; original Flow results and owner reports have not been treated as interchangeable.
