ABSTRACT:
A surface treating device such as a surface grinder in which power is transmitted to the operative elements of the assembly by a flowing gas, for example, air. The device is attached to a source of at least a partial vacuum, such as a vacuum cleaner. The motor fan unit of the vacuum cleaner together with a rotatable fan housed in the device form the power generating source which in turn operates the grinding member of the surface treating device in order to treat the work surface with an oscillating motion in a plane generally parallel thereto.
