Why does my Shark Lift-Away XL UV550 turn off by itself?
- KKarla FordAug 4, 2025
If your Shark Vacuum Cleaner turns off unexpectedly, it's likely due to overheating. To restart it, follow these steps: 1. Turn the selector switch to the Off position. 2. Unplug the vacuum. 3. Empty the dust cup and clean the filters. 4. Check for any blockages in the hose, accessories, and inlet openings. 5. Let the unit cool down for at least 45 minutes. 6. Plug the vacuum back in. 7. Move the selector switch to Setting I (Bare Floor) to restart the vacuum. If the vacuum still doesn't start, contact Customer Service at 1-800-798-7398.
