A:Answer Hi Robert, this is Krystal with Dyson. I am sorry to hear of the difficulty with your Dyson V6 Trigger. What you have described is a safety feature built into the machine. The machine pulsates ON/OFF when the trigger is held to alert you of an obstruction. It is just a matter of locating and removing the obstruction.
We will be happy to assist with this and want to ensure your vacuum is working as intended. Please contact us at askdysonUS@dyson.com, include your name and contact information, and we will be glad to assist. We look forward to hearing from you.
Best Wishes,
Krystal
