(2) The cleaning device X is attached so that the handle 3 can rotate (tilt) in the front-rear direction relative to the head 1, that is, can rotate about a left-right axis. However, the handle 3 may be rotatable (tilted) not only in the front-rear direction but also left-right. In this case, a universal joint or its structure can be used as the attachment mechanism 71. (3) Handle 3 is provided with grip 45 to serve as holding portion 31, but it is also possible to provide no grip and have holding body 41 and connecting body 43 serve as the holding portion. Handle 3 is provided with two connected members, holding body 41 and connecting body 43, but it may be provided with a single member. (4) Although the cleaning member 5 is detachable from the head 1, it may be attached to the head 1 in a non-detachable manner. (5) The handle 3 has an engagement mechanism 73 for enabling it to stand on its own. However, if the engagement mechanism 73 is not of interest, the engagement mechanism 73 and similar structures may not be provided. (6) A battery (secondary battery) 39 is provided as a power source for the motor 231 etc., but the power source may be a primary battery or may receive power directly from a commercial power source using an electrical cord. (7) The concave-convex relationship between the guide portion 215 of the base body 21 and the guided portion 222 of the movable body 22 may be reversed. In this case, the fixing screw 229 may be inserted from above. (8) The engagement portion 14 of the head 1 is provided at the front end of the arc-shaped upper surface 133 of the protruding portion 130 of the base body 21, but may also be provided at the middle (uppermost) position of the upper surface 133 or at the rear end of the upper surface. (9) The attachment mechanism 71 between the head 1 and the handle 3 is configured so that a pair of extension portions 423g of the handle 3 clamp the protruding portion 130 of the head 1 from the outside in a direction parallel to the pivot axis, but for example, the attachment portion 33 of the handle may be rotatably attached to the attachment receiving portion 13 of the recessed portion of the head 1. (10) In the cover body 25, the second cover body 28 forms the front side of an imaginary plane that passes through the center of a pair of through holes 132 of the mounting portion 13 and extends vertically. However, as long as the shaft portion 424 of the handle 3 can fit into the through hole 132, it may also form, for example, the upper side of an imaginary plane that passes through the center of the through hole 132 and extends front-to-back. (11) In the rotation mechanism 71 between the mounting portion 13 of the head 1 and the mounting portion 33 of the handle 3, the concave-convex relationship between the mounting portion 13 and the mounting portion 33 may be reversed. In this case, this can be realized by configuring the mounting portion 33 of the handle 3 with multiple members, with a virtual line passing through the through hole as a boundary. (12) The center line (rotation axis) of shaft portion 424 of rotation mechanism 17 intersects with motor 231. However, if the position of motor 231 is not of interest, it does not have to intersect with motor 231. (13) In terms of the positional relationship between the motor 231 and the mounting portion, the motor 231 is located on the front side as shown in Fig. 10, but it may be located on the rear side. Note that it is preferable in terms of weight balance that the motor 231, which is a heavy object, and the mounting portion are located in the center in the left-right direction. (14) The rotation shaft of the motor 231 faces downward, but depending on the structure of the conversion unit 232, it may extend in the front-rear direction. (15) The movable direction of the movable portion 11 is the front-rear direction, but it may be the left-right direction, or it may be both the front-rear direction and the left-right direction.
