5 Reasons Your Robot Vacuum Stops With No Error Message

Dirty cliff sensors Dust blocks the sensors that prevent falls, making the vacuum think there’s a cliff. Wipe the sensor windows with a dry cloth.

Jammed bumper sensors Hair or debris stuck in the bumper sensors tricks the bot into thinking it’s trapped. Clear any obstructions from the bumper area.

Hair-wrapped drive wheels Hair wrapped around a drive wheel can make the vacuum act stuck even on flat ground. Check and remove any hair from the wheels.

Low battery The battery may be too low to continue, but the error message is often vague or missing. Give the vacuum a full charge.

Software glitch Robot vacuums are finicky and sometimes just need a reset. Try a factory reset if cleaning and charging don’t work.
