Pros & cons

Segway Navimow X350

  • ✓Over three hours per charge with a fast 80 minute top-up
  • ✓Three years of 4G, GPS tracking and geofence included
  • ✓Vision-fused RTK navigated a tree-heavy test lawn confidently
  • ✓Quiet enough at 60 dB for night mowing
  • ✓About a third cheaper than a dealer-installed Husqvarna 450X
  • ✗Two-wheel drive; side-hill traversing is where the 50% rating falls apart
  • ✗No physical rain sensor
  • ✗Relocating the RTK antenna forces a remap
  • ✗Thin early-season grass can confuse VisionFence boundary detection
  • ✗Edge finish depends on the extra-cost Trimmer accessory

Sunseeker X7 Plus

  • ✓AWD with a 70% slope rating at a price below the Luba 2 AWD 5000
  • ✓14 in dual floating discs cut wide and follow uneven ground
  • ✓Camera plus RTK keeps positioning under trees where GPS-only mowers wander
  • ✓100 zones, virtual walls and no-go areas cover complex properties
  • ✓Built-in 4G tracking and geofence lockout
  • ✗App is cluttered and mapping with the single joystick is slow
  • ✗Small low obstacles like balls can be run over
  • ✗Stock at Sunseeker is often sold out and Amazon has been unavailable
  • ✗Slower than some rivals: reviewers saw it take roughly twice as long per pass
  • ✗Low body limits it on the steepest banks despite the AWD rating
