ABSTRACT:
A cleaner hose includes a hose body, connection cylinders to be connected to a cleaner operating pipe and a cleaner body, respectively, which are connected to ends of the hose body, respectively, and a reinforcement wire material wound in the hose body spirally and continuously over the whole length of hose body. The reinforcement wire material is shaped like a steeply slanted spiral in a predetermined length portion near one of or both of the ends of the hose body so that adjacent spiral portions of the reinforcement wire material are close to each other while a hose wall of the hose body is loosened toward the inner circumferential surface. On the other hand, the reinforcement wire material is shaped like a gently slanted spiral in an intermediate portion except the one of or both of the ends of the hose body so that adjacent spiral portions of the reinforcement wire material are separated from each other in the direction of a pipe axis.
