Average estimates: $250 to $420. Power washers can have pressures of 4,000 psi (pounds per square inch) to lesser pressures of maybe a few hundred and run by gas or electric. This means that professionals will probably use one with less pressure to clean a deck and maybe one with higher pressure to clean a patio.
To get the total cost per load for a washing machine, we add the costs for water, electricity, and water heating. 1  For water, we'll figure 40 gallons for a standard top-loading U.S. washer, and the national average of $5.44 per thousand gallons, which gives us $0.22 per load for water. For electricity to power the washer, we'll figure 0.256 kWh times a sample cost of 15Â¢/kWh, which gives us $0.04 for electricity.
