I mainly deal with vacuum cleaners, both service and repair, and have a few years experience now. 
I will try to repair most portable appliances, but they must be fairly small as I don't have much workspace. I try to avoid items such as carpet cleaners now due to their size and weight but please feel free to contact me if you think I may be able to help.
I can assure you that I will always offer an honest opinion and let you know if repair of your appliance is beyond my experience.
