When to replace the Vacuum belt

If your Vacuum is getting a little harder to push or doesn't seem to be picking up very well. Time to check the belt. The easiest way is when the machine is running and the handle is in the normal push mode take your foot and put it on the nozzle and push down, if you hear the brush roll stop or slow down it is time for a new belt. Belts under normal use probably need  be changed once or twice a year. More tips later.
