i do have the vacuum attachments, i also use brushes and clean it EVERY time i change the bobbin. i brush it out under and behind the bobbin area and up where the needle arm goes up and down. with every new project the machine gets vacuumed out well and a new needle- keeps everything running happily along :thumbup:
i bought my vacuum attachments from Clotilde's there are a number of different brushes. i use them on my sewing machine, long-arm machine and computer.
