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.

What the spreadsheet misses

Seguridad
Blades plus children, pets and hedgehogs: pick a model with lift sensors and do not run it at night.
Calidad
Frequent small cuts look tidy; edges still need trimming.
Flexibilidad
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.
Regulación
Mostly none; some towns restrict night-time running.
