If the cleaner is difficult to push with that setting, try the next highest setting. Most dealers which sell vacuum cleaners also sell replacement bags, belts, and certain accessories. Motors are equipped with bearings which contain sufficient lubrication for the life of the motor. Do not add lubricant to motor bearings. If your model has an agitator, it is equipped with two ball bearings that should be lubricated periodically by a Hoover Factory Service Center or an Authorized Hoover Warranty Dealer.
AMPs are merely the amount of electrical current a vacuum draws when the power is on.
An efficient vacuum cleaner design may provide better cleaning power with reduced electrical usage. WindTunnel technology is a patented air flow design which provides excellent cleaning effectiveness. Per your Owner's Manual, genuine replacement parts including bags and belts are specified in order to assure peak performance. Look for the trademark Hoover on all your part needs. Always turn your cleaner off and disconnect it from the electrical outlet.
