Meanwhile run with us two of these reliable "Robby". The Robby RR 002 has an edge cutting function. Simply "behind" put the charging station and send with "Start" on the journey. Upon completion of the entire round he comes in the normal mowing. As one can interfere in the term "cord" is for me not to enforceable, it is clear that the boundary wire is meant. Come out of the illustration but is clear. The programming is easy. We, 74 and 72 years old managed without the grandchildren. The two "Robby" Edit approximately 250 m² and 350 m² each 3 times a week and then run 2 and 3 hours. Result always perfect with kürzster cutting height. On both mowing areas are fruit trees and bushes individual I circled to the boundary wire as shown in the illustration. Works pefect. Trees and other Hinternisse be ticked briefly reset and mowed in new Richtrung on. The rain sensors function irish properly. In heavy rain, both the work have been set, the means, Mowers and down and docked the shortest path to the boundary wire, and to the charging station. The boundary wire can be shortened or verlangerbar. Have two tried ways. Manually rotate together, Schrummschlauch over it and ready to solder together Schrummschlauch about it and you're done. I use a boundary wire both cable strand and simple wire. Works. I know of no Rasenroboter where not trifles (lawn edge) must be nachgearbetet. I can not make any statements about the durability and spare parts supply. In our view, the lawnmower robot RR 002 is unrivaled, not just in relation to the price. We are very pleased with both our machines.
