The invention relates to a multirotor which comprises a main frame with a supporting shaft, a power device arranged on the supporting shaft, thrust rotors driven by the power device, and pressurization rotors which are coaxial with the thrust rotors and are positioned on the upper side of the thrust rotors, wherein the diameter of each pressurization rotor is smaller than that of each thrust rotor; and isolating guide plates are arranged between the pressurization rotors and the thrust rotors. The airflow friction is reduced, the working efficiency of the rotors is improved, the energy consumption is reduced, and the cruising time of the multirotor is prolonged.
