I am a quilter and need to clean my machine frequently, either daily or weekly. All of the literature states that "canned air" should not be used as it can attract moisture, so vacuuming is an alternative. I only gave it 4 stars for suction because I always want more suction. The nozzle worked very well and easily matched my Dyson pet vacuum. There was a plastic/oil smell, but that was fixed with a disinfectant spray (Lysol). It also works on window sills and small corners.
