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.

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 apparatus (10) for cleaning a surface includes a liquid delivery system (12) for storing cleaning liquid and delivering the cleaning liquid to the surface to be cleaned, a fluid recovery system (14) and a control system. The control system includes a controller (122) that is coupled to a fluid level sensing assembly (98). Methods of operating the same include sensing foam or liquid with the fluid level sensing assembly (98).

Abstract: An autonomous floor cleaner includes a base that is movable over a surface to be cleaned, a top plate coupled with the base, a collection chamber, at least one dirt inlet in communication with the collection chamber, and at least one sweeping element for sweeping dirt on the surface to be cleaned toward the collection chamber.

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: The present disclosure provides a surface cleaning apparatus that mechanically removes liquid and debris from a brushroll and stores the mechanically-removed liquid and debris onboard the apparatus in a first collection area. The surface cleaning apparatus also collects further liquid and debris from the brushroll by a source of suction including a vacuum motor or a pump and stores the collected liquid and debris onboard the apparatus in a second collection area.

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: 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 floor cleaning system includes multiple autonomous floor cleaners or robots. The robots are configured to share a mapping, navigation, and/or stain sensing system. A first robot carries the mapping, navigation, and/or stain sensing system, and a second robot receives information from the mapping, navigation, and/or stain sensing system of the first robot. The system can include at least one dry vacuuming robot and at least one deep cleaning robot.

Abstract: A surface cleaning apparatus, and in particular a steam mop, comprises a steam generator and a steam outlet fluidly connected to the steam generator to deliver steam to a floor surface. Steam from the steam generator can be applied to a cleaning composition applied to a stain on the floor surface. The cleaning composition can be applied directly to the floor surface, or indirectly via a cleaning pad.

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.
