A robotic lawnmower without boundary wires can revolutionize lawn care – no more laying and repairing wires, just precise navigation with RTK technology. The ECOVACS GOAT A1600 RTK promises exactly that. After more than 10 years with the Gardena Sileno+, which was regularly slowed down by broken cables, we needed an alternative. In this test, I show how the GOAT A1600 RTK performs in practice: from installation and mapping to mowing quality and safety. Is the cordless robotic lawnmower really convincing? Here is the answer.
