Narwal Flow 2 Review: Strong Vacuuming, Better Mopping, Premium Price

Narwal has entered Israel’s crowded premium robot-vacuum market with the Flow 2, a new model tested over recent weeks by Walla Technology. The review says the device stands out less for a single flashy feature and more for an unusual mopping system, strong vacuum specs, and advanced navigation.

The Flow 2 uses a continuous roller mop instead of the more common spinning pads, and Narwal says it delivers 31,000Pa of suction, 12N of downward mopping pressure, automatic detergent dosing, and heated water. The robot is black, about 35 cm wide and 9 cm high, while its dock is also black, measures roughly 36 by 36 by 43 cm, includes clean and dirty water tanks, a detergent compartment, filters, an LED status light, and a dust bag rated for up to 120 days. The robot also has a retractable LiDAR module, two 1080p front cameras with a 136-degree field of view, and AI that can identify obstacles, pets, and objects.

In daily use, the reviewer found the Flow 2 very good at both vacuuming and mopping. It handled mixed cleaning jobs well, navigated quickly and confidently, adapted suction automatically in Smart mode, and used heated water to keep the roller clean while working. Battery performance was also strong, with a full clean of about 110 square meters taking around two and a half hours and leaving roughly 40 percent battery, while a full charge took about four hours.

In tougher tests with flour, coffee grounds, leaves, water, thick sauces, and smeared dirt, it handled most debris well, especially on hard floors, but sometimes needed a second pass for stubborn stains. Its weakest point was edges, corners, and tight spaces under low furniture, where some debris remained. Narwal Flow 2 is priced at 5,490 shekels, which the review describes as premium but competitive compared with some flagships that cost more than 6,000 to 7,000 shekels.
