Abstract:
A cleaner includes a first cleaning module including a left spin mop and a right spin mop configured to contact the floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module configured to contact the floor in front of the first cleaning module, and a body supported by the first cleaning module and the second cleaning module. A point on the bottom surface of the left spin mop that receives the largest frictional force from the floor is located on a left-front side of the rotation center of the left spin mop, and a point on the bottom surface of the right spin mop that receives the largest frictional force from the floor is located on a right-front side of the rotation center of the right spin mop.
