Possible Causes
How to Fix / Troubleshooting
Safety first: Use only the original Dyson power adapter and dock. Do not open the power adapter.
- Check outlet and adapter: Plug another device into the same outlet to confirm power. Inspect the Dyson adapter cable for cuts or kinks.
- Dock bypass test: If possible, connect the adapter directly to the robot (some models allow this). If the robot powers on directly but not via the dock, the dock is faulty.
- Charge for extended time: Leave the robot on the dock for at least 3–4 hours. Some deeply discharged batteries take time before indicators light.
- Check main power switch: Ensure any underside or side power switch is in the ON position.
- Replace battery: If the robot never powers on after confirmed charging, replace the battery pack with a genuine Dyson unit.
If a new battery and known‑good adapter do not restore power, the main control board or internal fuse has likely failed and requires professional service.
