Pool cleaning

Weekly pool service vs Robotic pool cleaner (you still do chemistry)

工作量
假设

One month of pool care.

假设

Robot cycle hours per day it runs.

假设

Cleaning cycles per month.

假设

Months the pool is open.

人员
U.S. Bureau of Labor Statistics

BLS OEWS May 2025 national median hourly wage, SOC 37-2011.

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).

价格
推算 PoolRobots.com

Midpoint of $100-$150/month weekly professional service.

机器人
假设

A month of cleaning needs about 24 robot-hours (8 cycles of 3 hours).

推算 Maytronics US store

Midpoint of $849-$1,449 mid-range Dolphin models.

假设

Plug it in.

假设

Yearly parts (filters, brushes, eventually a motor) as a share of price.

假设

Useful life in years.

假设

Availability.

假设

Months lost to faults.

假设

Share of the service you still need: water chemistry, filter and equipment checks. Many owners do these themselves (then set 0).

假设

Your time is not costed.

假设

kWh per robot-hour.

假设

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

资金
假设

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

假设

Years in the NPV comparison.

假设

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

假设

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

假设

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

Cost per unit to 2035

Real terms (today's money). Robot hardware follows Wright's law; wages follow each country's history. Shaded band: robots-slow to robots-fast scenarios. Whirrwork 模型估算，并非事实。

What the spreadsheet misses

安全
Wrong water chemistry is the real risk; a cleaning robot does not test water.
质量
Robots scrub walls and floors well; leaves and debris loads vary.
灵活性
A service catches failing pumps and leaks early.
Edge cases
Oddly shaped pools and steps defeat cheaper models.
Customer experience
No strangers in the garden every week.
Jobs and redeployment
Pool technicians keep chemistry and repairs; cleaning visits shrink.
法规
None for private pools; public pools have water-testing rules.
