Kress Kress RTKⁿ 1,500 m² robotic lawn mower with OAS (Obstacle Avoidance System)

For gardens up to 1500 m², the Kress RTKⁿ KR171E carries the OAS (Obstacle Avoidance System) to detect and steer around fixed obstacles before contact. Weight 12 kg, 20 cm cutting width, adjustable height 30-60 mm, 40% max slope.

Positioning needs no buried wire: an RTK antenna receives real-time satellite correction, letting the mowing boundary be treated as purely virtual within the app. OAS complements this by spotting fixed obstacles on approach, for a smoother path than a simple contact bumper — useful at this size, where the number of obstacles to navigate around naturally increases. Off-limits zones still need to be marked manually on the map before the first mow.

Battery: 20V, roughly 3-hour recharge. A robotic lawn mower for medium-to-large gardens that skips the camera cost of the EyePilot line while keeping active obstacle detection.
