Abstract: The invention relates to a water extraction cleaning machine having a variable solution mixing valve adapted to create cleaning solution mixtures of variable constituent ratios. Clean water and detergent are provided from tanks supported on the water extraction cleaning machines. The size of the detergent inlet opening can be altered through rotation of a control knob provided on the outside of the water extraction cleaning machine. The knob is interconnected to at least one member which is adapted to vary the size of one of the detergent fluid inlet and the clean water inlet so that the ratio of constituent elements can be altered depending upon the cleaning application.

Abstract: A surface cleaning apparatus comprising an extractor has a primary fluid delivery system and an auxiliary fluid delivery system. A first button on a handle of the extractor controls the delivery of cleaning fluid from the primary fluid delivery system. A second button on the handle of the extractor controls the delivery of cleaning fluid from the auxiliary fluid delivery system, which includes a spot sprayer mounted to the base assembly through which cleaning fluid is delivered. The handle is provided with an interlock between the first and second buttons so that cleaning fluid cannot simultaneously be delivered by both the primary and auxiliary fluid delivery systems.

Abstract: A light-sensitive stain sensing system for an extractor for detecting and treating biological stains, such as food or pet stains. The stain sensing system comprises an ultraviolet light-emitting element, a visible light-emitting element, and at least one light reader. Ultraviolet and visible light beams are reflected off the surface to be cleaned into a light reader that measures reflectance values and transmits the values to a processor. The processor compares a relative reflectance value to a predetermined threshold value. The presence of a biological stain is indicated when the relative reflectance value is greater than the threshold value, and may trigger a controller to automatically adjust one or more cleaning parameters of the extractor.

Abstract: According to the invention, a surface cleaning device comprises an electrolytic cell for generating bleach for use with a cleaning pad. The electrolytic cell is in fluid communication with the cleaning pad for delivering bleach to a surface to be cleaned. According to another embodiment of the invention, the surface cleaning device is a hand-held cleaning device capable of selectively generating bleach at the request of a user directly in the cleaning pad. A sufficient amount of bleach for cleaning a surface can be generated within the electrolytic cell at the request of a user, eliminating the need for storing and transporting large quantities of bleach.

Abstract: An vacuum cleaning robot has a drive system adapted to autonomously move a base housing along a horizontal surface and is controlled by a computer processing unit. A dusting assembly is mounted to the base housing and is adapted to selectively rest on a surface to be cleaned. A suction source draws dirt and debris through a suction nozzle and deposits the same in the recovery tank. A power source is connected to the drive system and to the computer processing unit. The computer processing unit is adapted to direct horizontal movement of the base housing within boundaries of the surface to be cleaned based upon input data defining said boundaries.
