Why does my Shark WANDVAC WS640AE Vacuum Cleaner turn off on its own?

Your Shark Vacuum Cleaner might turn off on its own due to blockages or overheating. Here's what to do: * If the vacuum turns off because of blockages, turn it on and check the battery indicator lights. If recharging is needed, make sure the vacuum is off before plugging in the charger. * Empty the dust cup and clean the filters. * Check the wand, accessories, and inlet openings for blockages and remove them. * If overheating is the problem, allow the unit and battery to cool for at least 45 minutes until they return to room temperature. * Restart the vacuum by pressing the On/Off switch.
