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.
