Cleaning Performance and Features

The Braava 320 excels at basic dry sweeping and light damp mopping. It’s ideal for maintaining clean floors between deeper cleans, effectively picking up dust, hair, and light debris. Its straightforward cleaning patterns are sufficient for smaller, open areas. However, it may struggle with tougher dried-on messes or very large, irregularly shaped rooms due to its simpler navigation and smaller water reservoir.

The Braava 380 significantly outperforms the 320 in cleaning performance. Its NorthStar Navigation System allows for more systematic and efficient cleaning patterns, ensuring better coverage and fewer missed spots, especially in complex layouts. The larger water tank on the 380 also means it can complete larger areas with a single fill, and its improved damp mopping capabilities handle more stubborn dirt. This makes it a more effective solution for overall floor maintenance.

Navigation and Smart Features

The Braava 320 utilizes a basic, yet effective, random navigation pattern. While it covers the floor, it can sometimes result in less systematic cleaning and may require multiple passes in certain areas. It doesn’t offer advanced mapping or the ability to create virtual boundaries. This simpler navigation is suitable for smaller, uncluttered spaces where precise pathing is less critical for satisfactory results.

The Braava 380’s standout feature is its NorthStar Navigation System. This cube-based system creates a map of your room, allowing the robot to clean in efficient, back-and-forth lines, much like a human would. This leads to more thorough coverage and significantly reduced cleaning time. The 380 is better equipped to handle larger rooms and obstacles, making it a more intelligent and autonomous cleaning solution compared to the 320. (See Also: Pixel 6a Vs Iphone 12 )
