[0112] Specifically, a correction coefficient is set based on the difference in operating efficiency, and the cleaning evaluation value is dynamically adjusted to make the cleaning evaluation value more accurate.
[0113] Specifically, when setting the water spray volume f based on the cleaning evaluation value d, it includes:
[0114] The first cleaning evaluation value range (D1, D2), the second cleaning evaluation value range (D2, D3), and the third cleaning evaluation value (D3, D4) are preset.
