Latest Patents

One of Graupe's latest patents is the Dual Cleaning Mode Carpet Extractor. This carpet extractor 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, for maintenance cleaning, the valve is 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.

Another notable patent is the Squeegee Assembly. This assembly includes first and second protrusions interconnected to a support, to which front and rear flexible blades are mounted. The squeegee assembly is designed with a curved shape, allowing the flexible blades to be spaced at the center of the support where a suction tube is provided. The design ensures that appreciable reduction in the speed of air flow towards the suction tube does not occur, preventing the dropping of carried moisture.
