(11) Since water and the undiluted cleaning solution are separately jetted, there is no need to dilute the undiluted cleaning solution with water in advance, and the workability is excellent. (12) Since water and the washing stock solution are separately jetted, bubbling is generated by diluting the washing stock solution with water in advance, and the washing stock solution does not overflow from the washing stock solution tank 21 which is a tank for storing washing water. Excellent. (13) Since the cable bundle 25 is supported by the cable hanger 26 engaged with the upper traverse rail 101, there is no need to separately provide a cable rail or the like, and the productivity is excellent. (14) Even if the movement drive unit 3a becomes uncontrollable at the time of emergency stop or the like, the movement drive unit 3a is moved rearward by driving the contact / separation drive unit 3c, so that the transverse sprocket 3b and the transverse chain 102 mesh. Is released, so that the window or wall surface cleaning device 1 can be easily moved manually by pulling a string (not shown) such as a chain or a chain disposed on the window or wall surface cleaning device 1.
