For further noise, the rolling brush and the first driving motor can also intermittently rotate for a certain period of time, such as 100ms, every 5 minutes, so as to achieve a better noise reduction effect.

In the air drying mode, a fan in a main air duct of the floor washing machine drives air flow to circulate continuously, so that air drying can be realized; when the floor washing machine is placed on the base, the main air channel and the third air channel in the base form a closed circulating air channel, so that the air drying of the air channel is facilitated; under the effect of fan, the air current in the main air duct flows with the air current circulation in the third air duct in the base to utilize first driving motor and the heat that the rotation of second driving motor and give off, air-dry round brush and whole main air duct in the circulation air duct, improved air-dry efficiency, because there is not outside extra equipment, no other drying equipment yet, consequently, the in-process of air-drying, the cost does not have corresponding improvement, moreover, because the fan is in the air-dry mode down, with lower rotational speed rotation, still practiced thrift the cost.

The cleaning device provided by the utility model can also be used for a floor washer, and the cleaning device can be used for air-drying the rolling brush and the main air duct through the self structure, so that the interior of the floor washer can be kept clean all the time after the floor is cleaned, and the phenomenon of bacteria breeding caused by the humidity in the floor washer after multiple uses is prevented.

Compared with the existing floor washing machine with a base, when the cleaning device is applied to the floor washing machine, a closed circulating air channel can be formed, and the main air channel and the rolling brush of the floor washing machine are air-dried, so that the cleaning device has higher efficiency.

When the cleaning device provided by the utility model is used for cleaning the ground, the cleaning device has a good effect of low noise.
