The cleaning liquid tank 203 is connected with a spraying assembly 204. The cleaning liquid in the cleaning liquid tank 203 is sprayed onto the surface to be cleaned through the spraying assembly 204.

[0041] When a small push rod cleaning machine disclosed by the present invention is working, if it is wet cleaning, the spraying assembly 204 sprays the cleaning liquid in the cleaning liquid tank 203 onto the surface to be cleaned. Then, the host 1 is started, and the suction channel of the floor brush assembly 2 sucks the dirty water on the surface to be cleaned, passes through the inner cavities of the rotating member 5 and the connector 7, and then enters the cleaning channel in the host 1. Then, it enters the suction recovery pipe 1203 and is discharged into the dirty water recovery bucket 12 through the reversing communication pipe 1204. The gas in the dirty water recovery bucket 12 enters the filtering assembly 1207 through the gas outlet 1206, and then enters the fan 10, and is discharged outside the housing 109 through the air outlet 116 by the operation of the fan 10.

[0042] If it is dry suction, the path is the same as that of wet cleaning, that is, there is no need to spray the cleaning liquid.

[0043] The host 1 can also be disassembled and used separately. By attaching a brush head to the air inlet of the host 1, it can be used, which is very convenient.

[0044] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can obtain various other forms of products under the inspiration of the present invention.
