4 amps. Keep in mind, however, that amperage is not an accurate measure of power. Amperage is only the amount of electricity needed to run your motor. The Oreck XL vacuum cleaner has a small, efficient motor, while still maintaining high air speed (102 mph) and high brush revolutions (6500 rpms). The amount of air speed and how well your roller brush agitates your carpet determines how well the dirt is picked up off your floor, not how much electricity you use to start up your motor. High amperage usually indicates a heavy motor, thus a heavy vacuum. Many vacuum cleaner companies mislead the customer into believing that amperage is a measure of “power,” or how well it will “pick up”.
