The turn around time for cleaning at our sewing machine service center is also 4-6 weeks BUT we can make an appointment for cleaning. Our wonderful service man knows we hate being without our machines and says they can wait their turn with us rather than lonely on his shelves. The cleaning appointment will be 4-6 weeks out but you keep and use your machine right up to your appointment and then take it in on your appointment and pick it up the next day, except for the rare exception when your machine needs a part that he doesn't have in stock. Even then, if it is going to take more than a day or so to get the part and if the machine can be used temporarily without damage to the worn part, he will normally return the machine to you for you to bring it back when the part is in. Check with your shop to see if they also offer this service. :thumbup:
