Quick Answer: Buy the Worx Landroid if you want the lowest sticker price on a small flat lawn — the Landroid M covers about 1/4 acre for $600-900, per Worx retail pricing. Buy the Greenworks Optimow if you can catch it at street price, since it covers twice the area per tier, bundles 4G GPS tracking free for two years, and carries a 4-year warranty versus the Landroid’s 2-year (3-year registered) coverage — Best Buy cleared the Optimow 50H at $480.99 in July 2026, per Slickdeals/DealNews, which beats the Landroid M’s price while mowing a bigger lawn. Both are boundary-wire-only in their core lineups and both cap out at a 35% slope, so the real decision is price-versus-features, not capability.

Greenworks and Worx took the same navigation bet — stick with a buried boundary wire instead of chasing RTK or vision — but built very different value propositions around it. Worx competes almost entirely on price and a modular add-on ecosystem. Greenworks competes on what’s bundled in the box: cellular tracking, a longer warranty, and more coverage per model tier. Below we compare pricing, tracking, coverage, and warranty, then pick a winner for each kind of buyer.

Worx Landroid: best for the lowest sticker price

Worx Landroid M (WR140 / WR143)

Boundary wire · ~1/4 acre · 35% slope · $600-700
  • The cheapest name-brand way into a robot mower, usually well under $900, per Worx retail pricing.
  • Cut-to-Edge offset wheel and an AIA adaptive cutting pattern give a tidier finish than a straight boundary-wire mower.
  • GPS anti-theft tracking (Find My Landroid) is a separate purchase, so a fully tracked Landroid costs more than the base price implies.
  • Warranty is 2 years standard, 3 years if you register the mower — shorter than the Optimow's 4-year coverage.

Greenworks Optimow: best value at street price

Greenworks Optimow 50

Boundary wire · ~1/2 acre · 35% slope · $480.99-$900 street
  • Covers about twice the area of the Landroid M for a comparable or lower street price, per July 2026 Best Buy/Costco clearance pricing.
  • Integrated 4G GPS with a free two-year GreenGuide subscription — no separate purchase required for anti-theft tracking.
  • 4-year limited warranty, double the Landroid's standard coverage.
  • The trade-off: no wire-free model exists in the Optimow lineup, and at full $1,599.99 list price it costs far more than the Landroid for similar capability.
