Re-use the vacuum cleaner bags

I wanted to vacuum, the bag was full and I did not have a new replacement bag. So I put the full bag over the garbage container outside and under some shaking and with the help of long small pliers I got out the dust, hair, etc., shake it once in a while and you get lots of dirt out of the used bag. Use the pliers at the end to get out the rest. Put the bag in the vacuum cleaner again and it will go a long way (and you even saved some money as replacement bags are not cheap).
