On these numbers the robot option is clearly cheaper. The robot would sit idle most of the time; it pays off at higher volume or longer hours.

U.S. Bureau of Labor Statistics

BLS OEWS May 2025 national median hourly wage, SOC 37-3011.

U.S. Bureau of Labor Statistics

Wages and salaries were 70.0% of total employer compensation cost for private industry workers in June 2026 (ECEC), so total cost = wage / 0.70.

ilostat.ilo.org

Nominal 4.4% a year, 2015-2025 (ILOSTAT hourly earnings).

الأسعار
HomeGuide

Average per visit for a 1/8-1/4 acre yard ($30-$85).

الروبوت
افتراض

Mows completed per robot-hour for a quarter-acre yard (about 2 hours per full mow).

Mammotion US store

LUBA 3 AWD entry tier; larger tiers up to $3,299.

Zippy Lawnz (installer)

Professional installation up to 1 acre; DIY is $0.

مشتق Smart Lawn NY (installer)

$199 a year (midpoint of $149-$249 care plans) as a share of the entry price.

افتراض

Useful life in years.

افتراض

Share of allowed hours the mower can work (rain, charging).

افتراض

Mows lost to faults or stuck robots.

افتراض

Edging and trimming the robot can't do, as a share of a service visit you still pay for.

افتراض

Your own time is not costed here (you would spend it anyway, or enjoy it).

افتراض

kWh per robot-hour.

افتراض

Electricity price per kWh (USD). Check your bill; energy is rarely a big line.

التمويل
افتراض

Annual financing / discount rate. Nobody publishes yours; 8% is a round mid-2026 commercial borrowing guess.

افتراض

Years in the NPV comparison.

افتراض

Share of a human service price that is labour (rises with wages). Used to escalate and to adjust US service prices to other countries.

افتراض

Share of a robot service price that is labour (pilot, technician). The rest is equipment, which learning curves make cheaper.

افتراض

Share of a lease or RaaS fee that pays for hardware (learns down). The rest is service and support (moves with wages).

What the spreadsheet misses

السلامة
Blades plus children, pets and hedgehogs: pick a model with lift sensors and do not run it at night.
الجودة
Frequent small cuts look tidy; edges still need trimming.
المرونة
A service also blows, edges and spots problems.
Edge cases
Steep slopes, many separate patches and poor GPS/RTK signal break wire-free mowers.
Customer experience
You are the customer: no scheduling, no noise from big engines.
Jobs and redeployment
Small landscaping businesses lose the weekly mow but keep higher-skill work.
التنظيم
Mostly none; some towns restrict night-time running.
