I have a dedicated small shop vac under my LA specifically for cleaning it out with each bobbin change. I was told not to use compressed air on this specific machine as it can lodge the fuzz into crevices that can mess up performance and need a much deeper cleaning. I tried using a small hand held vac but it didn't have the suction needed, and I've got a lot of room for the bobbin case so don't need a small hose end to fit.
