Self-propelled surface treatment unit with environmental map

A self-propelled surface treatment unit(1) has a drive device(2) for the autonomous travel of the surface treatment unit(1) within an environment, an energy storage device(3), a data storage device (5) having an environmental map (4) of the environment, and a navigation device (6) for the navigation and self-location of the surface treatment unit (1) within the environment on the basis of the environmental map (4) having environmental zones(7,8,9,10). In order to improve the efficiency and service life of the energy storage device(3), the environmental map(4) has energy data(11) for at least two environmental zones(7,8,9,10), which indicates the amount of energy that the surface treatment unit (1) will require to treat the surface in each one of the environmental zones(7,8,9,10). 一种自主移行的地面处理设备(1)，包括：用于使地面处理设备(1)在环境内自主移行的驱动装置(2)，蓄能器(3)，具有所述环境的环境地图(4)的数据存储器(5)和用于地面处理设备(1)在环境内借助于环境地图(4)导航和自定位的导航装置(6)，其中，所述环境地图(4)具有子区域(7、8、9、10)。为了改善蓄能器(3)的效率和使用寿命，在此建议，所述环境地图(4)关于至少两个子区域(7、8、9、10)具有能量信息(11)，该能量信息表明地面处理设备(1)将需要多少能
