Residential snow clearing

Snow removal service (per visit) vs Autonomous snow blower robot

Whirrwork 模型估算，並非事實。 方法說明 · 預測紀錄

人工 · 每年US$800Snow removal service
機器人 · 每年US$2,139Buy a snow robot
回收期365 個月
成本交叉年份2035年前不會Base-case year (earliest to latest across scenarios)

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.

人員
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).

價格
推算 HomeGuide

Midpoint of $30-$70 per visit for a standard driveway.

機器人
假設

Clearings per robot-hour for a two-car driveway.

Yarbo US store

Yarbo Y40P core with snow blower module.

假設

DIY setup.

假設

Yearly parts share of price.

假設

Useful life in years.

假設

Availability.

假設

Clearings lost to faults or stuck robots.

假設

Visits you still need: heavy wet snow, the plough berm at the end of the drive.

假設

Your time is not costed.

假設

kWh per robot-hour.

假設

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

資金
假設

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

假設

Years in the NPV comparison.

假設

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

假設

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

假設

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

安全
Shovelling is a known cardiac risk for older people; that, not cost, is the strongest case here.
品質
Clears little and often, so snow never piles up.
彈性
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.
法規
None; keep it off public sidewalks unless your town allows it.
