Abstract
A cleaner includes a first extension pipe connected to a suction portion contacting a surface to be cleaned, and a second extension pipe coupled to a cleaner body having a driver generating suction force, and rotatably coupled to the first extension pipe. The first and second extension pipes operate in a first arrangement configured to allow the second extension pipe to be arranged in a longitudinal direction of the first extension pipe, and a second arrangement configured to allow the second extension pipe to rotate in a first direction from the first arrangement such that the first extension pipe and the second extension pipe are arranged to face each other. Such configuration enables a user to increase cleaning efficiency.
