No need for complicated wire installation. Set up of mowing maps can be done yourself via the app or by a professional ensuring correct operation from day one.

The device automatically maps the area without manual control. Visual AI-assisted mapping ensures accurate positioning. We recommend manual and professional installation when lawn edges are not clearly defined or for best results.

The algorithm uses RTK positioning and signal strength to recommend the optimal locations for the charging station and reference station avoiding concerns over weak signals or charging station return failures.
