Dyson Obstacle detection degradation

Robot vacuum repeatedly bumps into furniture or fails to slow down before impact.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Dirty front IR sensors, Stuck or misaligned bumper, Faulty obstacle sensor board, Strong ambient light interference

Safety first: Turn the robot OFF before cleaning sensors or bumper.

Clean front sensors: Wipe the front sensor windows with a dry microfiber cloth.
Check bumper travel: Press and release the bumper across its full width to ensure smooth movement.
Test in dimmer light: Try running the robot in a room without direct sunlight to see if behavior improves.

If obstacle detection remains poor, the front sensor/bumper assembly may need replacement.
