3 Things to Check When Your Robot Vacuum Shows Error Code 5

Check the wheels first Almost every time someone sees error code 5 on a robot vacuum, one of the wheels is jammed with hair, carpet fibers, or a small toy.

Inspect both drive wheels Turn the vacuum over and spin each wheel by hand. If either wheel does not rotate freely, remove the debris causing the blockage.

Clear the wheel sensors Dust or dirt on the wheel encoder sensors can also trigger error code 5. Wipe the sensors clean with a dry cloth.
