Latest Patents

One of her latest inventions is the Dual Cleaning Mode Carpet Extractor. This innovative device operates in either a restorative cleaning mode or a maintenance cleaning mode. It features a constant rate pump that dispenses clean solution through a manually operated valve to one of two lines with nozzles that 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. When restorative cleaning is desired, the valve is manually moved to dispense at the high flow rate, and a switch is also manually moved, resulting in the chassis being propelled at a slow working speed. Conversely, when maintenance cleaning is desired, the valve is manually moved to dispense at the low flow rate, and the switch is also manually moved, resulting in the chassis being propelled at a fast working speed.
