This invention relates to a device and method for detecting the cleanliness of down fabrics, belonging to the field of down quality testing technology. The cleanliness testing device includes a down washing bottle, a vibration mechanism for driving the down washing bottle in linear reciprocating motion, a water supply mechanism for providing cleaning medium to the down washing bottle, and a turbidity detection mechanism. The down washing bottle includes a bottle body structure composed of an upper bottle body and a lower bottle body, a water outlet on the lower bottle body, a screen located inside the water outlet, a gate valve assembly located outside the lower bottle body, and a limiting assembly. The water outlet is located in the direction of movement of the down washing bottle and is connected to the turbidity detection mechanism. This invention uses a vibration mechanism to oscillate the down sample. With the water outlet located in the direction of movement of the down washing bottle, the cleaning liquid is filtered through the screen by gravity-driven oscillation. The testing device maintains efficient filtration of the cleaning medium and improves detection accuracy.
