The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. A brushroll is provided on the base, along with various wipers, squeegees, and/or fluid dispensers.

Abstract: An accessory tool for an extraction cleaner having an accessory hose, a fluid delivery system, and a fluid recovery system includes a lens, a tool body, a spray tip, and a cleanout assembly. The tool body is connectable to the fluid delivery system and the fluid recovery system via the accessory hose. The lens couples to the tool body to form a suction nozzle volume therebetween. The tool body defines a fluid channel opposite the lens. The spray tip dispenses a cleaning fluid from the fluid delivery system onto a surface during a spray cycle of the extraction cleaner. The cleanout assembly selectively diverts the cleaning fluid from the spray tip and into the suction nozzle volume via the fluid channel during a clean out cycle of the extraction cleaner to thereby clean the lens and the accessory hose.

Abstract: A handheld cleaner includes a housing that at least partially defines an air pathway and a suction nozzle that defines a nozzle inlet in communication with a suction pathway. The suction pathway is configured to extract at least one of debris or liquid from a surface to the air pathway. An exhaust defines an outlet to the air pathway. A suction source is in fluid communication with the suction nozzle via the suction pathway. The suction source is configured to generate a working air stream. An operation angle sensor is configured to detect an operation angle of the handheld cleaner relative to the surface. A controller is in electrical communication with the suction source and the operation angle sensor via an electrical pathway. The controller is configured to control an amount of suction generated by the suction source based on the detected operation angle.

Abstract: The present disclosure provides a cleaning system and various related apparatus for grooming a pet. The cleaning system can comprise components dedicated to pet grooming or can adapt a surface cleaning apparatus or tools normally used for cleaning floors and upholstery to instead groom a pet. The cleaning system can include two supply tanks, and a supply valve controlling the flow of cleaning solution out of one of the tanks.

Abstract: An extraction cleaner is provided with a removable recovery tank having a recovery container, a drain opening quick-empty valve, and an actuator assembly for emptying the recovery container. The drain opening can be provided on a lower portion of the recovery container. The actuator assembly can selectively open the valve. At least a portion of the actuator assembly can be provided on an upper portion of the recovery container.

Abstract: Self-cleaning features for extraction cleaners and attachments for extraction cleaners, such as accessory tools, wands, and/or hoses, are provided. The self-cleaning features are configured redirect cleaning fluid from a fluid supply system of the extraction cleaner into a working air or fluid recovery path of the extraction cleaner, including, but not limited to into the working air or fluid recovery path of a tool, wand, and/or hose of the extraction cleaner.

Abstract: An autonomous vacuum cleaner includes an autonomously moveable housing carrying a vacuum collection system for generating a working air flow for removing dirt from the surface to be cleaned and storing the dirt in a collection space. Distance sensors for position sensing are mounted to the housing. The distance sensors can be staggered and/or positioned on one or more sides or above a brush chamber for a brushroll.

Abstract: The present disclosure provides a surface cleaning apparatus that includes a fluid delivery system for mopping a floor surface after sweeping debris from the floor surface. The surface cleaning apparatus can have a brushroll, a collection bin that receives dirt and liquid swept by the brushroll, and a cleanout member configured to empty the collection bin and mechanically remove dirt and liquid accumulated on one or more internal surfaces of the base.

Abstract: An extraction cleaner includes a steam delivery system, a liquid delivery system, and a recovery system, and includes multiple cleaning modes, including a first cleaning mode in which components of the steam delivery system, liquid delivery system, and recovery system are active, a second cleaning mode in which components of the delivery system and recovery system are active, and a third cleaning mode in which components of the steam delivery system are active. Methods for operating an extraction cleaner are also provided.

Abstract: An accessory tool assembly adapted to couple with a hose of an extraction cleaner including a suction source includes a tool head and at least one fluid distributor for supplying and directing a cleaning fluid therethrough. The tool head includes a front end and a rear end opposed to the front end, wherein a longitudinal direction extends through the front and rear ends and a transverse direction extends perpendicular to the longitudinal direction. The tool head includes a working surface on an underside of the front end that defines a working surface edge. A plurality of agitators extend from the working surface adjacent to at least a portion of the working surface edge and define a first interior area therewithin. An extraction nozzle is positioned in the first interior area and defines at least a portion of a suction air inlet.

Abstract: A vacuum cleaner includes a housing having a suction nozzle opening, a source of suction in fluid communication with the suction nozzle opening for generating a working air stream through the housing, and a multiply-adjustable debris collecting blade coupled along the rear of the suction nozzle opening for collecting debris.

Abstract: An accessory tool for an extraction cleaner having an accessory hose, a fluid delivery system, and a fluid recovery system includes a lens, a tool body, a spray tip, and a cleanout assembly. The tool body is connectable to the fluid delivery system and the fluid recovery system via the accessory hose. The lens couples to the tool body to form a suction nozzle volume therebetween. The tool body defines a fluid channel opposite the lens. The spray tip dispenses a cleaning fluid from the fluid delivery system onto a surface during a spray cycle of the extraction cleaner. The cleanout assembly selectively diverts the cleaning fluid from the spray tip and into the suction nozzle volume via the fluid channel during a clean out cycle of the extraction cleaner to thereby clean the lens and the accessory hose.

Abstract: An autonomous floor cleaner includes multiple occupiable space sensors for position and/or proximity sensing. Data from the occupiable space sensors can be used determine areas of occupiable space in proximity to the autonomous floor cleaner. Methods for exiting a trapped condition, obstacle avoidance, and path planning are disclosed.

Abstract: A floor cleaner can include a housing adapted for movement over a surface to be cleaned and at least one edge cleaning brush provided on the housing. The edge cleaning brush includes multiple cleaning implements which rotate on different axes. A gear system, such as a planetary gear system, can drive one cleaning implement at a lower speed than another cleaning implement.

Abstract: A surface cleaning apparatus includes a controller coupled to a sensor or a set of sensors that collects and transmits data to a remote computing device. The surface cleaning apparatus can use wireless or networking technology with a protocol for wireless communication with the remote computing device. The remote computing device is configured to identify an event at the surface cleaning apparatus and/or a change in the cycle of operation of the surface cleaning apparatus based on the transmitted data. Sensor data can be transmitted from the remote computing device to a different surface cleaning apparatus.
