Cleaning apparatus

A cleaning apparatus, comprising:

• a housing, a rolling brush, and a cleaning assembly;
• wherein,
• the housing comprises a supporting housing and a base housing, an air suction pipeline is arranged between the supporting housing and the base housing;
• the cleaning assembly is arranged on the supporting housing, is located above the air suction pipeline, and faces the rolling brush;
• the cleaning assembly comprises a cleaning medium inlet and a plurality of cleaning medium spray orifices;
• and
• the plurality of cleaning medium spray orifices faces the rolling brush, and lengths of flow channels from the cleaning medium spray orifices to the cleaning medium inlet are equal;
• and wherein along extending directions of the flow channels, the flow channels comprises flow channel branches of multiple layers, the multiple layers are separated and overlaid in a space.

A ground cleaner, comprising:

• a handle main body and a cleaning apparatus connected with the handle main body,
• wherein the cleaning apparatus comprises:
• a housing, a rolling brush, an air suction pipeline, and a cleaning assembly;
