ABSTRACT:
A carpet extractor (10) operable in either a restorative cleaning mode or a maintenance cleaning mode includes a constant rate pump (96) which dispenses clean solution through a manually operated valve (98) to one of two lines (100, 102) having nozzles which restrict dispensing to high and low solution flow rates. In the preferred form, clean solution is dispensed at the high flow rate directly upon the carpeted surface and at the low rate upon the agitating brush (88). When restorative cleaning is desired, the valve (98) is manually moved to dispense at the high flow rate and a switch (110) is also manually moved resulting in the chassis (18) being propelled at a slow working speed. When maintenance cleaning is desired, the valve (98) is manually moved to dispense at the low flow rate and the switch (110) is also manually moved resulting in the chassis (18) being propelled at a fast working speed.
