Robot Vacuum Doesn’t Navigate Properly or Bumps Into Walls

These sensors detect collisions. Clean the area around the front bumper with a soft cloth and check whether it can move freely.

Dust on the IR sensors prevents obstacle detection. Wipe them carefully with a lint-free cloth. Don’t use water!

For models with LiDAR or a camera, cleanliness is essential. Carefully clean the lens or cover with a microfiber cloth. Fingerprints or scratches can interfere with navigation.

If you use virtual boundaries, check their position. Remove them temporarily to make sure they are not causing the problem.

Camera-based robots need light. Make sure there is enough lighting during cleaning, or enable “night mode” in the app.

Cliff sensors can react incorrectly on very dark or reflective floors. In most apps, you can adjust the sensitivity. Experiment with the settings.

If you have moved furniture, the saved map may no longer be accurate. Delete old maps and let the robot map the area again.

Software updates often include navigation improvements. Check regularly whether new updates are available.

If the bumper is broken or does not spring back, a more involved repair is needed, or the bumper must be replaced.
