Does the washing machine have to be cleaned every time?
Generally speaking regularly cleaned, but can be cleaned according to the actual situation, as long as the filter after gifts, will affect the next time, you can wash.
Personally, it's not always clear, but it's best to clean up in time. For reference only.
Your idea from another point of view is reasonable, the net in the direction of flow design is irreversible, stolen goods is running out, but much more stolen goods is not easy to dry, is a hotbed of bacteria, the net can filter stolen goods cannot excessive bacteria, and it is mainly the fallen fabric filter clothes fiber, more will be blocked lose effectiveness.
