5. Operating Your Redkey MGC500
5.1. Mowing Modes and Path Planning
The Redkey MGC500 utilizes advanced C-TOF technology for precise positioning and intelligent path planning. It can mow in parallel or perpendicular patterns, ensuring comprehensive coverage of your lawn. After recharging or relocation, the robot resumes its previous path, preventing repetitive cuts and missed spots. A quick mode is available for smaller lawn areas (e.g., 7 square meters).

5.2. Adjusting Cutting Height
The cutting height of the robot lawn mower can be flexibly adjusted between 3 cm and 7 cm using the companion app. The smart blades automatically adjust when encountering tall or dense grass to ensure successful mowing.

5.3. Automatic Charging and Resumption
When the battery level drops below 15%, the MGC500 automatically returns to its charging station. Once it reaches 90% charge, it will resume mowing from where it left off. This ensures continuous operation without manual intervention.
5.4. Obstacle Avoidance and Slope Handling
Equipped with collision sensors, the robot adjusts its direction to avoid obstacles and protect your lawn. Its two-wheel drive system allows it to handle slopes up to 45% (24 degrees) with ease.
