Hi Wolf! The suction power for the Air Lift is great for picking up dirt and various debris. The brushroll allows you to pick up dirt deep within the carpets, then you can turn the brushroll off for just suction on hard floors. If you have any further questions on this model feel free to give us a call at 1-800-944-9200 (M-F 8a-6p EST). We're here for you! -Karissa, Hoover Customer Care
