The present invention relates to the related art of fabric cleaning machines, and in particular to a fabric cleaning machine with a water circulation function.

There are often many large-scale fabric products at home, making it impractical to clean them directly with water. However, if not cleaned regularly, they tend to accumulate dirt and grime. Therefore, fabric cleaning machines have become increasingly popular in recent years. Nevertheless, regular fabric cleaning machines usually require changing the water after each cycle, which can be quite inconvenient and wasteful, often necessitating multiple cycles. Moreover, considering large surface areas of the fabric products needing cleaning, the cleaning machine itself needs to be larger, making it cumbersome to use and place.
