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: 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 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 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.
