Abstract: A carpet cleaning apparatus is disclosed with a loop agitator. The loop agitator comprises a spindle with a plurality of flexible loops attached to the spindle. A blade is provided in close relative proximity to the agitator for severing hair and other fibers that become entangled on the agitator. A de-foaming device is included that automatically dispenses a de-foaming chemical. The de-foaming device comprises at least two electrodes that allow foam to complete a circuit to open a solenoid valve. Negative vacuum pressure is allowed to disburse the de-foaming chemical. The device also comprises a basket with a mesh bag for straining wastewater and removing debris. Wastewater drains into a wastewater tank where an electrode switch is provided for activating a wastewater pump.
