Floor treatment system

The invention relates to a soil working system with a self-propelled and self-steering floor treatment unit, which comprises an electrically driven floor treatment unit and a rechargeable power supply unit, and with a central charging station for recharging the power supply unit, with the floor treatment unit above the other associated electrical connecting elements, which are arranged at the loading station and the soil cultivating unit are, with the charging station can be electrically connected. In order to develop the tillage system such that it enables an improved electrical coupling of the mutually associated connecting elements, the invention proposes that at least one of the mutually associated connecting elements is resiliently held.
