Then turn on the vacuum source 4000, which rotates at high speed and generates a vacuum in the rotary brush chamber 5020. The rotary brush 5040 contacts the horizontal plane and rotates around the axis at high speed and beats the horizontal plane, generating a dust-containing airflow. The dust-containing airflow then enters the dust collection module 3000 through the cleaning module air duct 5060 for dust-gas separation. The dust is stored in the dust collection chamber 3020, while the airflow enters the vacuum source 4000 and is discharged to the outside until the end.

[0044] When this embodiment is in the play application scenario, first connect the play module 5400 to the vehicle body 1000, and the bottom of the play module 5400 maintains a vertical gap with the horizontal plane. Then start the switch button 6400, and the driving wheel of the driving component 6000 rotates, causing the vehicle body 1000 to move on the horizontal plane. The child can control the direction by operating the steering wheel 2020. At the same time, the driving wheel can rotate forward and backward, generating forward and backward movement, thereby achieving the purpose of driving entertainment.

[0045] The advantages of the present utility model are as follows: It not only has a play function but also has a dust suction function, which can not only improve children's driving ability but also increase the fun of life, and at the same time facilitate the cleaning work of the home environment.

[0046] The above is only the preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art can make several deformations and improvements without departing from the creative concept of the present utility model, and all should be covered within the protection scope of the present utility model.
