Narwal Flow: two-minute review
The Narwal Flow is a high-end, self-emptying hybrid robotic vacuum with an especially unusual and impressive mopping system. I've been testing one out for the past fortnight, and the performance is such a mixed bag that coming to a definitive conclusion is tricky. On one hand, its mopping is among the best of any robovac I've tested. The mop pad is mounted on a wide roller, which extends outwards to reach into corners, and uses hot water to clean both your floor and itself. The system works remarkably well.
