Illustratively, as shown in fig. 8, if the cleaning device needs to travel to the right, a leftward force F1 is applied to the main body 3, so that the main body 3 rotates to the left about the first rotation axis 9, and the main body 3 tilts to the left, so that the user applies a rightward force to the handle 4 to cause the cleaning assembly 1 to travel to the right, thereby changing the cleaning direction of the cleaning device. Similarly, as shown in fig. 9, if the cleaning device needs to travel to the left, a rightward force F2 is applied to the main body 3, and the main body 3 is rotated to the right about the first rotation axis 9 to tilt the main body 3 to the right, so that the user applies a leftward force to the handle 4 to cause the cleaning assembly 1 to travel to the left, thereby changing the cleaning direction of the cleaning device.
