Why does my vacuum cleaner overheat and switch off?

If the vacuum cleaner stops during use and feels hot, it may be protecting itself from overload or airflow restriction. Switch it off, unplug it and let it cool fully before you continue. Do not keep resetting or restarting it if you smell burning, see smoke or think a part is damaged.

1. Check whether the dust bag or dust container is full. Empty or replace it, then make sure it is seated correctly. Expected result: the appliance should regain normal airflow.
2. Clean the filters and allow them to dry completely before refitting. A blocked or damp filter can make the motor work too hard. Expected result: the vacuum should run more steadily after cooling and reassembly.
3. Inspect the hose, tube and floor head for blockages. A restriction here can make the motor overheat even when the machine still sounds like it is running. Expected result: air should pass through the full length of the cleaner.
4. Confirm that the cord is fully unwound if your model uses a mains cable. A tightly coiled cord can contribute to heat build-up on some appliances. Expected result: the cleaner should operate with less strain.
5. If the machine shuts off again after a short time, or if it repeatedly becomes very hot, stop using it and contact the retailer or store where it was purchased.

Do not cover the cleaner while it is running and keep vents clear during use. Repeated overheating can point to a deeper fault, so it is safer to stop early if cooling and cleaning do not help. Generic troubleshooting.
