RedGarnett..why would a vac be bad for your machine?curious.
i know for sure the canned air is...my dealer told me not to use it. just pushes the lint further into the machine.
I also take my Janome in once a year..i plan on her lasting a long, long time.
I have had her about 5 years now..and this is the way i have always cleaned the machine..my dealer even sells the mini attachments..but they want to much money for them..
