Abstract: A cleaning machine and path control method therefor has a main motor and fan blade unit arranged between upper and middle housings. Three groups, each including edge wheel motor, edge wheel gear set and edge wheel worm are distributed in a triangle between its middle and lower housings. When the main motor is turned on, it draws air through the fan blade unit, from between its chuck and a surface to be cleaned, with the chuck attached to the surface to be cleaned. When the edge wheel motor is turned on, it drives a cloth through the edge wheel gear set, so that friction is generated between the cleaning cloth structure and the surface to be cleaned, thereby cleaning the surface to be cleaned.
