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 providing a barrier for an autonomous floor cleaner includes an artificial barrier generator that radiates one or more infrared signals. An autonomous floor cleaner can be configured to detect the infrared signals, and can react by altering course. Methods for containing an autonomous floor cleaner within a user-determined boundary are disclosed.
