If your vacuum is hard to push, the height adjustment is probably set too low. Raise the height adjustment one setting at a time higher until the unit is no longer hard to push. The height adjustment dial is located on the base of the vacuum. Also, check that the belt isn’t broken. Broken belts can make the vacuum difficult to push as well.
