Classification: CPC B  G | IPC B  G

Claim 7:
8. The vehicle-mounted sensor cleaning device according to claim 1, further comprising:
a liquid nozzle that sprays a liquid toward the sensing surface; and
a liquid supply device that supplies the liquid to the liquid nozzle,
wherein:
the gas supply device comprises an air pump; and
the control section is configured to:
control the gas supply device to increase an output of the air pump stepwise upon determining that the value of the object detection accuracy becomes lower than the first threshold value;
determine whether the value of the object detection accuracy has changed to be higher than the first threshold value after operation of the gas supply device for a predetermined time period; and
control the liquid supply device to operate the liquid supply device upon determining that the value of the object detection accuracy has been kept lower than or equal to the first threshold value after the stepwise increase in the output of the air pump.
