• a head part to which a member for cleaning is attached;
• and
• a handle part connected to the head part and for being gripped by a user,
• wherein the head part includes a top surface part forming an upper surface side, to which the handle part is connected and a bottom surface part forming a lower surface side, and
• the bottom surface part is formed to be freely attachable or detachable with respect to the top surface part,
• wherein a length of the handle part is capable of changing to be 78%, 56% and 34% with respect to the longest case,
• wherein the top surface part is an approximately rectangular member in plan view being elongated in a Y-axis direction, a X-axis direction is perpendicular to the Y-axis in the plan view,
• raised parts are formed on the upper surface side of the top surface part, the raised parts are close to both ends of the top surface part in the Y-axis direction, the raised parts are higher than a sunk part which is close to a central part of the top surface part in the Y-axis direction, and a height of the top surface is gradually sink from the raised parts to the sunk part,
• wherein ribs protruding downward are formed on a lower surface of the top surface part, the ribs comprise high ribs which are largely convex downward and formed close to the central part of the top surface part in plan view and low ribs which are convex downward in a lower degree than the high ribs and formed at portions other than the central part,
• the high ribs are formed so as to be largely convex downward and the low ribs are formed so as to be gradually reduced in height from the high ribs toward fringe part on the top surface part.
