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: An ultrasonic cleaning tool for cleaning a surface has a transducer and a horn for generating and transmitting vibrations to a surface to be cleaned. Cleaning solution can be supplied to the ultrasonic cleaning tool or the surface to be cleaned, and operation of the ultrasonic cleaning tool can agitate the surface and cleaning solution. The tool can be provided as part of a system for cleaning a surface, and the system can include an extraction cleaner or a cleaning cloth.

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 apparatus for cleaning a surface includes a liquid delivery system for storing cleaning liquid and delivering the cleaning liquid to the surface to be cleaned, a fluid recovery system and a control system. The control system includes a controller that is coupled to a fluid level sensing assembly. Methods of operating the same include sensing foam or liquid with the fluid level sensing assembly.

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: A brushroll for a surface cleaning apparatus includes a brush dowel defining an axis and having opposing bristle supports and a shroud surface between the opposing bristle supports, and a plurality of bristles protruding from the bristle supports. The shroud surface includes opposing convex curved surfaces extending between the bristle supports which intersect the shroud surface at outside corners.

Abstract: A method is provided for manufacturing an aqueous formulation of a manganese-containing coordination complex, by combining a source of the manganese-containing coordination complex with a source of chloride anion in an aqueous solution, and simultaneously with or following combination of the source of chloride anion and the source of manganese-containing coordination complex in the aqueous solution, providing a source of a dianion to the aqueous solution to form the aqueous formulation.

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: A room air purifier has a body with a frame at least partially defining an interior chamber and an opening to the chamber. A purification mechanism in the chamber includes one or more filters and one or more blowers. A panel is configured to removably mount to the body and cover the opening to the chamber. A base mounted to the body, and each leg of a set of legs is mounted to the base. A nonwoven fabric portion covers at least part of the body. The blower when activated generates an inflow through the nonwoven fabric portion and a filter, and an outflow though the body, all while hidden from view in what to an observer looks like an article of furniture.

Abstract: A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.
