Abstract: A surface cleaning apparatus includes a supply tank, a fluid dispenser, a brushroll rotatable about an axis, a brushroll motor configured to rotate the brushroll in a forward direction about the axis and a backward direction about the axis, and a controller. The controller executes a scrub mode in which the brushroll is oscillated forward and backwards about the axis to scrub a surface to be cleaned and break up a stubborn stain on the surface.

Abstract: Systems and methods for self-cleaning an extraction cleaner are provided. The extraction cleaner includes a suction nozzle defining a suction pathway, a fluid distributor configured to dispense cleaning fluid to a surface to be cleaned, and a nozzle flushing manifold configured to spray cleaning fluid into the suction pathway of the suction nozzle.

Abstract: An autonomous floor cleaner can include a brush chamber, a brushroll rotatably mounted in the brush chamber, a controller adapted to control the operation of the autonomous floor cleaner, and a fluid delivery system with a supply tank and at least one fluid distributor configured to deposit cleaning fluid onto a surface to be cleaned.

Abstract: A surface cleaning apparatus is operable in a plurality of cleaning modes, including at least a wet cleaning mode and a dry vacuuming mode. The surface cleaning apparatus has a suction source, a suction inlet port in fluid communication with the suction source, a fluid dispenser, a pump in fluid communication with the fluid dispenser, a motor coupled with a brushroll to drive the brushroll, and a floor type sensor. Operating parameters of the apparatus may be automatically adjusted based on a detected floor type.

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: An autonomous surface cleaning device can include a base adapted for movement over a surface to be cleaned, a drive system configured to move the base over the surface to be cleaned, and a vacuum collection system for removing at least debris from the surface to be cleaned. A main controller and a compliance control module can be operably coupled with at least one of the drive system or the vacuum collection system.

Abstract: A surface cleaning apparatus includes a fluid delivery system and a recovery system, and is operable in a plurality of user-selectable cleaning modes, including at least a wet vacuuming mode and a dry vacuuming mode. The fluid delivery system has a fluid dispenser that may comprise a spray manifold for wetting a brushroll. The recovery system includes a tank that may have a baffle to separate liquid and/or debris from a working airstream. Operating parameters of the apparatus may be automatically adjusted based on a detected floor type. The apparatus can dock with a tray for recharging and/or self-cleaning.

Abstract: A cleaning tray is provided for docking an extraction cleaner, including upright or robot extraction cleaners, for self-cleaning. The cleaning tray may include one or more sprayers for spraying a cleaning fluid toward a suction nozzle, brush chamber, and/or agitator of the extraction cleaner. Systems for self-cleaning extraction cleaners are also provided.

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, behind a sensor cover. The distance sensors can be staggered and/or positioned above a brush chamber for a brushroll.

Abstract: A system for refilling, emptying and/or recharging of an autonomous floor cleaner includes a docking station adapted to be coupled with a household plumbing infrastructure. The docking station can be provided on a household appliance, which may be a toilet, a dishwasher, or another appliance coupled with the plumbing infrastructure.

Abstract: An autonomous floor cleaner, such as a robotic 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. A bumper is provided on the housing and provides obstacle sensing redundancy. The bumper can be provided with a cliff sensor actuator member that activates an associated cliff sensor upon an impact or obstacle event.

Abstract: Systems and method for self-cleaning extraction cleaners, including upright or robot extraction cleaner are provided. In one system, a tray can be provided for docking the extraction cleaner during the self-cleaning mode. The tray may include one or more sprayers for spraying a cleaning fluid toward an agitator of the extraction cleaner. In another system, a nozzle flushing manifold mounted on the nozzle assembly of the extraction cleaner includes a plurality of distributor outlets configured to spray cleaning fluid into the suction pathway.

Abstract: An autonomous floor cleaner can include a brush chamber, a brushroll rotatably mounted in the brush chamber, a controller adapted to control the operation of the autonomous floor cleaner, and a fluid delivery system with a supply tank and at least one fluid distributor configured to deposit cleaning fluid onto a surface to be cleaned.
