Regularly:
Always unplug the vacuum before you begin your maintenance regime. It sounds obvious, but even accidentally knocking a switch can cause vacuum cleaner parts to start working unexpectedly, which could result in physical or electrical injury.If your vacuum stops working abruptly, this may mean it has overheated. Switch off and unplug, waiting for at least half an hour for it to cool down before using again. This may be an indication that vacuum repairs are needed, so it may be wise to seek expert advice if the problem cannot be found.
