I mainly deal with vacuum cleaners, both service and repair, and have a few years experience now. 
Other items include carpet cleaners, radios, tape recorders, coffee machines, steam cleaners, toasters, sewing machines, electric lawnmowers and hedge cutters, lamps, dehumidifiers, etc.
In fact I will try most portable appliances, 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.
