Hi ​@susanccj26,

Welcome to the Dyson Community! Please note I’ve removed your image to keep your machine’s serial number private.

Your Dyson cordless vacuum is engineered to pulse on and off rapidly to alert you if something is preventing airflow from passing through the machine. This could be due to a filter overdue for a wash, and/or a blockage or obstruction within the floor tool, wand or bin inlet.

After the pulsing alert, your machine will shut down for protection to prevent damage to the motor.

Take a look at our troubleshooting article for help resolving this:
