Replace the worn blades of your robot lawn mower with the Roborock Endurance Maaimesjes 12x. These mower blades cut grass shorter with more power and last longer, so they wear out less quickly than regular mower blades. You can easily attach the mower blades to your robot lawn mower with the 12 included screws. You can use these mower blades with the RockMow Z series, S series, and RockNeo Q series.
