Oh yes, I do know your problems and it would kill you here.
About your options: well, that one with a vacuum cleaner sounds nice but it is impossible, and yes, the sacks are for reuse. And as I am a typical human, I prefered to keep this bigger bucket to a smaller one - simply because I wanted to finish as soon as possible. You know, farmers (my husband being a nice example) like cheap working power which is reusable and takes care of herself/himself! *Grins*
