To protect the cleaner from possible damage due to overheating a thermal cut out will switch off the electrical supply if the motor gets too warm. A blockage in the hose will restrict the airflow and cause overheating.The best way to check for a restriction or blockage is to remove the hose from the product, hold it upright and drop a £1 coin down from the top. If the coin pops out at the other end your hose is not blocked. If it gets stuck in the hose then there is an obstruction which can be easily removed by carefully pushing the blockage out using a broom handle or similar pole.

Your cleaner has been fitted with a thermal cut out to protect the vacuum cleaner from damage should it get too hot and overheat. Blockages or dirty filters may cause this to happen, the safety cut off will activate and switch off  the electrical supply.

 If the cleaner has cut out, simply unplug  and check for a blockage or dirty filters. Please look at the advice guides for loss of suction and not picking up dirt, for tips on how to clean the filters fitted to your product. Once all of the checks have been done allow the cleaner to cool down which is usually around 45 minutes. Once its cooled down and plugged back in it should start to work again as the cut out is designed to automatically reset.
