Pros & cons

Worx Landroid S WR165

  • ✓Complete wire install kit in the box, with far more wire than an eighth acre needs
  • ✓Cut to Edge offset blade and a floating disc, the same as the pricier M and L
  • ✓Battery swaps into the whole Worx 20V Power Share line
  • ✓Street prices around $600 to $750 undercut its $999.99 list by a wide margin
  • ✗2.4 in maximum cut height rules out tall-fescue lawns
  • ✗2.0Ah pack means short runs and many dock trips
  • ✗Bumper-only obstacle handling; ultrasonic avoidance is a paid add-on
  • ✗No GPS or cellular without the Find My Landroid module

Worx Landroid L WR155

  • ✓Lowest cost per acre of any name-brand half-acre robot, often near $1,000 or less
  • ✓Widely stocked at big-box retailers, so returns and parts are easy
  • ✓Floating blade disc self-levels over ruts and roots
  • ✓Cut to Edge and rain delay are standard, not add-ons
  • ✓Power Share battery doubles as a spare for other Worx tools
  • ✗Roughly an hour per charge means a lot of dock trips on a full half acre
  • ✗30% slope rating is the weakest in its price class
  • ✗No obstacle avoidance beyond the bumper without the ACS kit
  • ✗Wire install is a real afternoon-plus job and wire breaks are on you
