On these numbers people are clearly cheaper. The robot would sit idle most of the time; it pays off at higher volume or longer hours. Payback is longer than three years, which is longer than many robot contracts and some robot companies.

What the spreadsheet misses

Keselamatan
Shovelling is a known cardiac risk for older people; that, not cost, is the strongest case here.
Kualitas
Clears little and often, so snow never piles up.
Fleksibilitas
A service brings a plough for big storms.
Edge cases
Heavy, wet or very deep snow; gravel drives.
Customer experience
Wakes nobody at 5 a.m. (unless it beeps).
Jobs and redeployment
Seasonal snow contractors lose small driveways first.
Regulasi
None; keep it off public sidewalks unless your town allows it.
