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.
Calculating the cost-per-load of laundry (top-loader). 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 15 /kWh, which gives us $0.04 for electricity.ront-loader economics: 1  Front-loaders cost about $100 more than top-loaders, but common savings are $100/yr. 2  The only time a front-loader won't pay for itself is if you already use cold water almost exclusively, and you do a lot less than the average 7.5 loads per week.
