PURPOSE: To peel off and remove contaminant without damaging a part to be cleaned by shooting flight bodies formed from a member not mechanically deforming the part to be cleaned toward the part to be cleaned so as to form an angle of 60° or less with respect to the part to be cleaned.

CONSTITUTION: A blower is operated so that the opening 2 of a housing 1 is allowed to approach a surface 13 to be cleaned and air is injected in the tangential direction of the inside wall of the housing 1 from an air introducing port 5. The flight bodies 3 such as sponge bodies in the housing 1 come into slide contact with the inside wall of the housing 1 according to the vortex of air to rotate thereon and also come into slide contact with the surface 13 to be cleaned at an opening part 2 through a net member 4 and the surface 13 to be cleaned is abraded with the flight bodies 3 and contaminant is peeled off from the surface 13 to be cleaned to carry out cleaning. At this time, since the flight bodies 3 can not pass through the net member 4,,(hey circulate in the housing 1 while draw a spiral locus. Since the flight bodies 3 are fed under pressure by air to draw a moving locus along the inside wall of the housing 1, they are shot at an angle α with respect to the surface 13 to be cleaned but the angle α becomes 60° or less.
