Narwal Flow is Narwal’s latest flagship vacuum+mop combo, and in this review I focused on the two “fresh takes” that actually matter: one changes how it approaches mopping, and the other is all about getting into corners. On paper it’s stacked—built-in AI, twin cameras for obstacle avoidance, and onboard LiDAR that lets the robot sit lower than previous models. But I don’t care about buzzwords; I care about what happens on real floors. So I ran it through real-world tests to see if those new ideas hold up versus the usual rotary and roller mop setups. If you’re shopping specifically for strong mopping performance, better corner reach (thanks to the dual side brush approach), and features like liquid spill detection, this is the kind of robot that could legitimately move the needle—assuming it performs the way it claims. I also call out an important product update: the detergent dispenser shown in my video does not fit the Narwal Z cartridge, and Narwal still hasn’t confirmed how the built-in soap dispenser situation works—right now the included detergent instructions say to add one capful directly into the clean water tank.
