Sunseeker X3 Plus vs Worx Landroid M WR147
vs
Quick take: The Sunseeker X3 Plus costs $3 less; the Sunseeker X3 Plus skips the boundary-wire install entirely while the Worx Landroid M WR147 needs a perimeter wire laid but doesn't care about tree cover or satellite signal; the Sunseeker X3 Plus is rated for a larger lawn (13,068 sq ft); the Worx Landroid M WR147 cuts taller (up to 3.5"), which matters for fescue and warm-season grasses.
