I use one and it works well. My sister had a real mess with her Jenome from not cleaning it out - she dusted top, but didn't realize how much gets down in all the mechanisms. We took her machine apart and it was like felt in there! Since then, we have made an effort to vacuum our machines out between quilts. Makes a BIG difference. I got my attachments for like $10 in the Clotilda catalog. Money well spent! :thumbup:
