How Much Does It Cost to Run a Electric Pressure Washer in Australia? (2026)
Electric pressure washers draw 1,300 to 2,500 watts but only while the trigger is pressed. An hour of washing typically uses about 1 kWh, and the water cost is often larger than the electricity.
A typical electric pressure washer (1,800 W) costs A$0.63 per hour, or about A$9.45 per month at 0.5 hours a day in Australia. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (1,300 W) | A$0.45 | A$0.23 | A$6.82 | A$83.04 |
| Typical (1,800 W) | A$0.63 | A$0.32 | A$9.45 | A$114.97 |
| High (2,500 W) | A$0.88 | A$0.44 | A$13.12 | A$159.69 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.5 h/day ≈ 328 kWh per year.

- Pretreat with detergent so you rinse rather than blast.
- Store it drained and indoors so the pump lasts.
