PURPOSE: To provide a surface-cleaning suction apparatus having a suction head member by which the work of cleaning is made possible even if the apparatus is reciprocally traveled forward and rearward.
CONSTITUTION: The apparatus is so composed as to be reciprocally traveled along a surface 30 to be cleaned. A suction sleeve member 7 having a suction opening 14 is so composed as to be adjacent to the surface 30 and as to be apart therefrom by being angularly moved round rotary supports 51, 61. A suction head member 20 consisting of side blades 21, 22 fastened to the front and rear sides in the direction of traveling and an inter blade 23 provided between these side blades is mounted on the suction opening 14. The suction sleeve member 7 is so composed as to be angularly moved by causing the work of suction force to the suction head member 20 and as to do the work of suction for the surface 30 by bringing the suction opening 14 into contact with the surface 30.
