5 Things to Know About Robot Vacuum Navigation

Methodical navigation is far more efficient than random bumping. Robots that move in systematic rows cover the floor with fewer passes and less battery drain.

Random-bump models rely on collision sensors to change direction. They eventually cover the whole floor, but they waste time and battery by revisiting areas repeatedly.

Laser-based navigation maps your room in real time. These robots create a precise layout and avoid obstacles without bumping into them.

Camera-based navigation uses visual landmarks to track position. It works well in good lighting but can struggle in dark rooms or with reflective surfaces.

Gyroscope-only navigation is a budget compromise. It keeps the robot moving in straight lines but cannot build a map, so it still misses spots.
