The shoe sole washers we had used until now had brushes, but the brushes themselves became dirty, making it impossible to thoroughly clean and sanitize the washers themselves.Bosher was selected because the machine itself was maintained in a hygienic manner and its cleaning capacity was satisfactory.Also, the machine itself can be installed in various locations as long as it has an air and water source and a power supply. Therefore, we install the Bosher not at the factory entrance, but near the heating room, next to the topping room, and other places where shoe soles tend to get dirty, so that they can be cleaned immediately on the spot.
