I used this on my Shih Tzu, as it was a burden for him to go to the groomer due to his old age. I am not a professional, but an ordinary person using this on only one dog in a general household, so the frequency of use is less than that of a groomer, about once every 2-3 months. I have cleaned only the areas I could reach, but since it is used, please forgive any scratches, stains, or signs of use. Thank you for your understanding. - Model: DC-6 - Power Type: AC Power Dog Pet Trimming Groomer Haircut Thank you for viewing.
