The assembly steps of the sponge cup brush are as follows:
Firstly, thread the wire into the cup brush.
Then, use scissors to cut the sponge cup brush into small pieces in an orderly manner.
Next, place the brush in a soap box and bend it at both ends.
Finally, ensure that the brush can rotate flexibly, so that a portion of the bristles protrude from the bottom of the box.
Close the lid of the box, so that the simple and non electric vacuum cleaner is ready.
