Why does my vacuum cleaner overheat?

If your vacuum cleaner overheats, this could be due to the following reasons:
Blockages - check the hose and head for any obstructions.
Filter - always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
Vacuum bag or container- check the vacuum back or container, if this is full the suction performance will reduce.
