en.Wedoany.com Reported - The Narwal Flow 2 robot vacuum and mop demonstrates superior obstacle avoidance capabilities compared to most competitors in its price range during cleaning. In controlled laboratory and home environments, the device effectively avoids obstacles such as wires, tissues, socks, small toys, and even pet waste. Its navigation system is driven by two 1080p cameras, a LiDAR sensor, and AI object recognition software. Narwal claims the technology achieves millimeter-level obstacle avoidance accuracy, capable of identifying obstacles as close as 0.2 inches away. Tests show that the Flow 2's bumper was not triggered when approaching common furniture like table legs, with no actual contact occurring, and no need for manual intervention.
This model features a track-style mopping pad instead of a roller design, officially referred to as a treadmill structure. The track mop has a larger contact area with the floor compared to rollers, providing more uniform downward pressure distribution. The device internally uses hot water to rinse the mop pad to remove dirt, performing well in tests for cleaning sticky, dried stains such as syrup and dried fruit juice.
In terms of suction, laboratory test data shows that the Narwal Flow 2 achieves an average suction efficiency of 81.02% on hardwood floors and 43.38% on short-pile carpets. For comparison, in the same test, the Mova P10 Pro Ultra achieved a pickup rate of 99.27% on hardwood floors, while the iRobot Roomba Combo 10 Max reached 73.62% on short-pile carpets. Home tests indicate that the device effectively removes visible pet hair and most dust on short-pile carpets, but its suction performance on carpets is weaker than some competitors.
The Narwal Flow 2's track mop offers advantages in cleaning hard floors, making it suitable for living environments primarily with hard flooring. The device handles small toys or wadded tissues smoothly and pays special attention to heavily soiled areas such as spills for focused cleaning. In carpet-dominated homes, since mopping plays a core role in overall cleaning functionality, careful consideration is needed to determine if it matches the user's needs.
