20080196193 | EXTRACTOR WITH AUXILIARY FLUID DISPENSER - 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. | 08-21-2008 |
20090078284 | Extraction Cleaning with Heating - A portable extraction surface cleaner apparatus wherein a surface to be cleaned is heated to an elevated temperature and a cleaning fluid is applied to the surface to be cleaned sequentially or simultaneously. The cleaning fluid is removed from the surface by suction from a vacuum source. Power is applied alternatively or simultaneously to a heating element and to the vacuum source for recovering the deposited cleaning fluid. | 03-26-2009 |
20090090021 | Extraction Cleaning with Plenum and Air Outlets Facilitating Air Flow Drying - A method of drying a surface using a portable cleaning apparatus by removing a mixture of air and liquid from the surface through the application of suction to the surface through a suction nozzle while moving the suction nozzle along a first direction, separating the air and liquid, pressurizing the separated air and passing the pressurized air in a second direction transverse to the first direction and along the surface laterally of the suction nozzle. The pressurized air is directed along the surface from a location spaced from the suction nozzle. | 04-09-2009 |
20090183335 | VACUUM ACCESSORY TOOL - A vacuum accessory tool comprises a nozzle body that forms a suction nozzle and that has an electrical element comprising one or a combination of an illumination element adapted to illuminate a surface to be cleaned, an ion generator or ozone generator to purify a surface to be cleaned and eliminate odors. The tool can further include a power generator for supplying power to the electrical element. The illumination element can further emit light in the ultraviolet spectrum to illuminate stains on the surface to the cleaned. | 07-23-2009 |
20100078318 | Surface Cleaning Device With A Bleach Generator - 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. | 04-01-2010 |
20110079248 | Extraction with Temporary Suction Interrupt - An extractor has a duct door moveably mounted to a working air conduit for movement between a first position at which normal suction at a suction nozzle is reduced and a second position at which normal suction at the suction nozzle is unreduced. An actuator is connected to the duct door for selectively moving the duct door between the first position and second position. In one embodiment, a suction leak hole is formed within the working air conduit and the duct door is moveable with respect to the leek hole to selectively fluidly open and close the leak hole. In another embodiment, the duct door is moveable within the working air conduit to selectively fluidly restrict the working air flow in the working air conduit and the actuator selectively moves the duct door between the first and second positions. The suction reduction selectively increases the cleaning solution dwell time. | 04-07-2011 |
20110132406 | LOW MOISTURE EXTRACTION DEEP CLEANING - An extractor has a plurality of fluid delivery needles mounted to a housing in fluid communication with a fluid distribution system and positioned to penetrate a carpet surface to deliver a cleaning solution below the surface of the carpet and into the carpet nap. Soiled cleaning fluid is removed from the surface with suction. A method of cleaning a carpet or a pet coat having a nap comprises injecting cleaning fluid, such as a foam detergent, directly into the nap and removing soiled cleaning fluid from the carpet. | 06-09-2011 |
20110146720 | DRY VACUUM CLEANER WITH SPOT CLEANING - A vacuum cleaner has a cleaning powder distribution system and an actuator connected to the powder distribution system for selectively dispensing powder from the powder distribution system to soiled spots on a floor surface. In addition, a cleaning fluid distribution system is adapted to selectively distribute a liquid cleaning solution to the soiled spot. A propellant, in the in the form of an aerosol or compressed gas can be used to distribute the cleaning powder to the floor. A method of cleaning a spot on a surface comprises applying a selected volume of fluid cleaning solution to a selected area on the surface to be cleaned, applying a selected amount of cleaning powder to the selected area and extracting the applied cleaning solution and cleaning powder from the selected area on the surface to be cleaned. | 06-23-2011 |
20130174874 | EXTRACTION WITH TEMPORARY SUCTION INTERRUPT - A method of cleaning a surface comprising applying cleaning solution to a surface, applying suction to the surface to remove the applied cleaning solution from surface, and selectively interrupting the suction to the surface for a selected time to increase dwell time of the cleaning solution on the surface. In one embodiment, the suction is interrupted when a moveable duct door fluidly and selectively opens and closes a suction leak hole within the working air conduit. In another embodiment, the suction is interrupted when a actuator selectively moves the duct door between the first and second positions within the working air conduit to restrict the working air flow in the working air conduit. The suction reduction selectively increases the cleaning solution dwell time. | 07-11-2013 |
