The payback calculator

If you currently pay for mowing, this is the whole decision. Enter your numbers:

Robot vs. your mowing service

Assumptions, stated plainly: ~$45/season running cost (blades + electricity) and an 8-season service life. Battery replacement mid-life ($100–300) would extend payback by 1–3 months at typical numbers.

Mow it yourself today? Then the robot buys time, not dollars: a half-acre lawn is roughly 35–70 hours a season of pushing. Whether that's worth $1,500 is yours to price — the worth-it guide walks the whole decision honestly.

Running costs owners actually report

The trend is your friendWire-free capability that cost $2,500+ in 2024 starts near $1,000 in 2026, and new brands enter every season. If your lawn is simple, buy on the next sale. If your lawn is hard (steep + shaded), each generation genuinely mows better — the premium you pay is for solving your specific problem, so match tech to yard first: navigation guide, slope guide, 1-acre picks, small-yard picks.
