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.
