FLOOR TREATMENT SYSTEM

摘要

The invention relates to a floor treatment system comprising a self-propelled, autonomous floor treatment unit, which contains an electrically driven floor treatment assembly, in addition to a rechargeable power supply unit and an electrical controller and comprising a central charging station for recharging the power supply unit. According to the invention, the charging system has an emitter for emitting infra-red target radiation and said target radiation can be captured in a directionally dependent manner by a receiver of the floor treatment unit, in order to automatically align and position the latter at the charging station. The aim of the invention is to improve the floor treatment system to such an extent that the latter can be reliably guided towards the central charging station. To achieve this, the emitter has a first emitter unit for creating a far field in the target radiation, in addition to a second emitter unit for creating a near field in the target radiation, whereby the near field emanating from the charging station extends over a wider, shorter area than the far field.
