Its compact size allows it to work in tight spaces and near obstacles, while automated mowing cycles ensure even coverage and consistent lawn appearance. The product is optimized for low-maintenance use, enabling repeated short mowing sessions that reduce grass stress and promote uniform growth.

How to use

Install the perimeter wire following the layout of the lawn to define the mowing boundary and place the charging station on level ground with access to a power outlet. Configure the initial settings through the compatible app, set mowing schedules and preferred cutting height, and allow the mower to perform calibration runs so it learns the area. Regularly inspect blades and underside for debris and check boundary wire integrity. Recharge the mower at its station as needed; the device returns to the charging base automatically when battery is low or when a scheduled pause occurs.

Usage recommendations

For consistent results, schedule frequent short mowing cycles rather than infrequent long cuts; maintain recommended cutting height for the grass species, keep the lawn free of larger debris, and perform periodic blade maintenance. Ensure firmware and app updates are applied to maintain connectivity and functional performance.
