Product review (3 stars): Still in progress
Still a work in progress. Tried it with the whole house vac and that collapsed the plastic tube, so no good there. then tried a small
shop vac and did get more lint out. It is surpirzing how far down the vent goes down, but swishing it back and forth, more lint did come out. But when I pull out the lint screen there is still some lint clinging to the bottom of it. Our granson the engineer will be put to work on this at Christmas.

I did see a very similar set up in Consumers Report and they did manage to get quite a bit more lint out of some of the testing, so I am not giving up.
