3 Ways to Cut Your Electric Pressure Washer Energy Bill
- 🌱
Pre-soak surfaces with detergent to loosen grime, reducing the time you need to run the motor at high pressure.
- 💡
Use the appropriate nozzle — a 25° nozzle covers more area than a 0° nozzle, reducing total spray time.
- ⚡
Work in sections rather than randomly to avoid re-spraying areas, minimizing total run time.
The pump motor draws a startup surge of about 3,000–4,500W for a few seconds before settling to its running wattage.
