Vacuum cleaner won't turn on? Battery, filter and overheating protection

Unplug the vacuum and remove the battery, if you can, before cleaning. Wash filters only if the manual allows it, and dry them for at least a day. Don't use a swollen battery.
Step by step
Charge the battery or check the socket
On a cordless vacuum plug in the charger and check the LED lights up. On a corded one check the socket with another appliance.
Wait 30–60 minutes
After long vacuuming or with a clogged filter the motor overheats and the protection cuts it out. Let it cool down.
Clean the filters and bin
Empty the bin or replace the bag. Clean the filters as described in the manual. A clogged filter is the most common cause of overheating.
Check the tube and brush
A blocked tube or a brush wrapped in hair can stop the vacuum. Clear blockages and cut the hair off the brush.
Check the trigger and lock
On vacuums with a trigger lock, check it's set correctly. On many models you have to hold the trigger the whole time.
Check the cable
On a corded vacuum inspect the cable along its whole length. A repair shop replaces a frayed or scorched cable.
- the battery is swollen or won't hold a charge
- you smell burning or see sparks
- the cable is damaged
- the vacuum won't start despite clean filters and a charged battery

Repair or buy new?
Filters and the battery are sensible repairs. Replacing the motor in a cheap vacuum rarely pays off, in a more expensive cordless one it usually does.
