Vacuum runs only when the charger is plugged in and stops immediately when unplugged.

Safety: Do not continue to operate the vacuum in this condition; it stresses the charger and electronics.

• Confirm behavior: Charge fully, then unplug and test. If it stops immediately, the battery is not storing energy.
• Inspect battery: Check for swelling, cracks, or damage. Do not use a damaged battery.
• Replace battery: Install a new genuine Dyson battery pack. Dispose of the old battery at a recycling facility.
• Check charger: Ensure the charger is correct for your model and functioning properly.
