If the unit is overheating, or getting hot when vacuuming, your bag may be clogged with dirt, so the motor is not able to exhaust air. Air has to pass through the vacuum to obtain maximum performance.
How to solve this issue?
Hand wash the bag in warm water with a mild detergent, rinse and air dry. If the problem persists, please contact your nearest service center using our Service Center Locator here.
