Is opened and the time T during which the cleaning work is possible is set in the timer counter t of the control unit 30 (8), and the cleaning work is enabled during the predetermined time T. Then, the time display lamp 33 is turned on by the number corresponding to the set time,
As the timer counter t is decremented and counted each time a unit time elapses, the lamp 33 is sequentially turned off to display the elapse of time (9).

When the cleaning operation is performed in this way and t = 0, that is, when a predetermined time T has passed (10), the motor 10 is stopped and the solenoid valve 23 is closed (11) to return.

As described above, in this embodiment, since the motor 10 is driven and the solenoid valve 23 is opened only for a predetermined time when the coin is inserted, the operator can operate the dust suction nozzle 6
Can be operated to suck and clean the dust in the automobile interior, and the dust that cannot be sucked can be operated to be scattered using the blowing nozzle 25 or collected to a place where the dust can be sucked, so that the dust can be cleaned without a corner.

Further, since the dust suction nozzle 6 and the blow-out nozzle 25 are integrated and the suction port 24 and the blow-out port 29 are adjacent to each other, as shown in FIG. 8, the dust blown up by the blow-out nozzle 25 is immediately absorbed by the dust suction nozzle. It can be inhaled at 6 and can be effectively cleaned. Further, when the normal dust absorption force cannot be obtained due to the clogging of the filter 17, the work is interrupted and the fee is refunded, so that the user is not lost.
