This is a strange use case: use a traditional vacuum cleaner to clean a robotic one. The official robot cleaning guide says you have to clean the dusty filter with tapwater. If you do so you close the pores of the filter by creating a thin, cement-like layer on the filter's surface and it will be useless after a couple of cleanings. To prevent this clean your Xiaomi filter just by using an old vacuum cleaner instead and you will never have to buy new filters again in every month or so! Just connect the Xiaomi Mop Pro's filter to the old vacuum using this adapter and turn on the suction and in a few seconds the filter will be cleaned properly. The adapter is compatible with the standard 35 mm vacuum tubes. I have designed the adapter to fit to my Xiaomi Mop Pro's filter but as I have uploaded the Fusion 360 design file you can easily alter the model to match with other filters.
