No robotic mower will cut right to the edge unless it can go over the boundary. The YUKA Mini typically leaves about 5-10cm uncut along edges and borders, which is standard for most robotic mowers.

Regarding the acute angle with raised borders, this could present a challenge. The YUKA Mini has good navigation, but very tight angles (less than 45 degrees) can sometimes be problematic as the mower needs space to manoeuvre. It might not cut perfectly in these tight corners, leaving slightly more uncut grass in those specific areas. You may need to occasionally trim these acute angle sections manually for a perfect finish.
