6 Reasons Your Robot Vacuum’s Map Is Corrupt

The robot lost its map or never built a complete one. Mapping is the backbone of room-by-room cleaning, and a missing or partial map causes random bumping.

You moved furniture or objects. If the robot sees a changed layout, it gets confused and falls back to bumping around randomly.

A sensor is dirty or blocked. Dirty cliff sensors or bumpers prevent the robot from navigating correctly, corrupting the map.

The battery died mid-run. An interrupted cleaning cycle can corrupt the map data, forcing the robot to start over.

The base station is poorly placed. If the base station is in a cluttered or off-center spot, the robot may lose its reference point.

Your home has dark floors or an open plan. Some robots struggle with low contrast or large open spaces, so add visible landmarks or a boundary strip.
