How do you install a Hoover Runabout vacuum belt?

To install a Hoover Runabout vacuum belt, first, unplug the vacuum for safety. Remove the bottom plate by unscrewing it, then take out the old belt and brush roller. Place the new belt around the motor shaft, loop it over the brush roller, and reassemble the brush roller and bottom plate before securing it back with screws. Finally, plug in the vacuum and test it to ensure it functions properly.
