The method is executed by the controller and comprises: controlling the first motor to start in response to a dust collector starting request; obtaining a first rotating speed of the first motor and a liquid level height of liquid in the dust cup; comparing the first rotating speed with a preset first motor rotating speed threshold, and comparing the liquid level height with a preset first liquid level height threshold; and when the first rotating speed is greater than or equal to the rotating speed threshold and the liquid level height is less than the first liquid level height threshold, controlling to start a second motor. On this basis, the present invention further provides a system and a device. According to the present invention, the volume of liquid in the dust cup can be monitored before and during work of the dust collector, a situation that the liquid flows out due to the fact that the content of the liquid in the dust cup is too high, which causes damages to a motor and other parts, is prevented, and the service life of all the parts in the dust collector is prolonged.
