Possible Causes

Clogged filters restricting airflow, Blocked wand or floor head, Motor cooling vents obstructed by dust, Failing motor drawing excess current

Safety: Turn off and remove the battery. Allow the unit to cool for at least 20–30 minutes.

Clean filters thoroughly: Tap or wash (if allowed) pre-motor and HEPA filters and let them dry completely.
Clear all blockages: Inspect wand, joints, and floor head for obstructions.
Clean vents: Use a soft brush to remove dust from motor housing vents.

If the vacuum still overheats quickly, the motor may be failing and should be replaced by a technician.
