What Is an Uneven Lawn?
• Sloped areas or rolling hills
• Tree roots pushing up from below
• Soil dips and soft patches
• Gravel, exposed roots, or changing terrain
Why Do Robot Mowers Struggle on Uneven Terrain?
• Loss of traction on steep inclines
• Blades missing grass in deep dips or bumps
• Skipping or bouncing across rough patches
• Inconsistent cut heights on variable terrain
• Damage to lawn mower parts
• Not enough power to work on slopes
How Do Robotic Lawn Mowers Work?
• RTK GPS (Real-Time Kinematic positioning) for precision navigation
• AI sensors for obstacle detection and terrain recognition
• All-Wheel Drive systems for traction and slope handling
• Smart apps for custom mowing schedules, cutting height, and geofencing
The Best Lawn Mower for Rough Terrain

| Feature | Yarbo | Competitor A | Competitor B |
|---|---|---|---|
| Max Climbing Angle | Up to 68% (35°) | 45% (24°) | 35% (19°) |
| Navigation Accuracy | RTK GPS with ±2cm precision | Standard GPS, ~±10cm accuracy | Perimeter wire only |
| Obstacle Avoidance | AI + Ultrasonic + Vision-Based | Bump sensors only | Basic proximity detection |
| Performance on Wet Terrain | Smart traction control & rerouting | Slips or stalls on soft areas | Requires dry conditions |
| No-Go Zones | App-based virtual boundaries | Manual wire installation | Limited, wire-dependent |
| Blade Height Adjustment | Auto-adjusts in real-time | Manual or semi-automatic | Manual |
| Multi-Zone Mowing Support | Yes, with app control | Limited | Often not supported |
| Setup Complexity | No wires, easy mapping in-app | Moderate (requires wire) | High (wire + manual calibration) |
Slope Mastery
• Slopes of up to 68% (35°)
• Wet, slippery grass
• Rocky or root-filled sections
Precision Cutting
• Dynamic blade adjustment to maintain cutting height on uneven ground
• Shock-absorbing suspension for a smoother ride
• Real-time surface scanning to avoid scalping or skipping
Advanced Obstacle Avoidance
No Perimeter Wires Required

User-Friendly App:
• Adjustable cutting height and mowing frequency.
• Customizable schedules for multiple lawn zones.
• Real-time location tracking and mowing history.
• Smart alerts for weather changes or obstacles.
User Concerns About Adapting to Complex Terrain
• Will it get stuck in soft ground or holes?
• Can it manage the incline behind my house?
• My lawn has tree roots and dips—won't it miss patches?
Tips to Prepare Uneven Lawns for Robotic Mowing
• Fill holes deeper than 2 inches, so that the mower blades are able to reach the grass and cut it.
• Remove stones, large branches, or thick debris; this may damage the lower blades' sharpness as well as the mower's hardware.
• Use Yarbo's app to map the lawn and set boundaries, mark no-go zones where there are trees, water bodies or flower beds
• Trim overly tall grass for the initial mow
