Safety first: Immediately stop using the vacuum, turn it off, and remove the battery. Do not continue to operate a sparking motor.

Allow the unit to sit in a dry environment for at least 24–48 hours if moisture exposure is suspected.
Do not attempt to open the motor housing; this is not user-serviceable.
Replace the complete main motor assembly or main body module. Continued use can cause fire or further damage.
