Why does my Shark Navigator UV300 turn off by itself?

If your Shark Vacuum Cleaner turns off unexpectedly, it's likely due to overheating. The motor's protective thermostat might have been activated. Here's what to do: 1. Turn the power off and unplug the vacuum. 2. Empty the dust cup and clean the filters. 3. Check for any blockages in the hose, accessories, and inlet openings. 4. Let the unit cool down for at least 45 minutes. 5. Plug the vacuum back in and turn it on to restart.
