ABSTRACT:
A carpet cleaning machine for uniformly spreading a dry carpet cleaning powder onto a surface and working the dry carpet cleaning powder into the surface. The cleaning machine includes base having a hopper integrally formed therein, distribution slots on the bottom of the hopper, a rotary powder agitator inside the hopper, wheels for supporting the base over a floor surface and for rotating the powder agitator, a metering gate for controlling the dispensing of the dry carpet cleaning powder, a trigger located on the cleaner handle for controlling the metering gate, and a plurality of motor driven vertical axis rotary brushes for working the dry carpet cleaning powder into the carpet. The dry carpet cleaning powder is dispensed onto the carpet and allowed to sit for a short period of time to allow the dry carpet cleaning powder to absorb the dirt contained in the carpet. After the dry carpet cleaning powder has dried and absorbed dirt, the dry carpet cleaning powder and dirt are vacuumed from the carpet with an ordinary vacuum.
