What Affects the Cost of Running a Electric Pressure Washer
Pressure Washers Are Used Infrequently, Keeping Total Costs Low
Most homeowners pressure wash a few times per year (driveway, deck, siding). A 30-minute session at 1,800W uses 0.9 kWh ($0.15). Even 10 sessions per year costs under $2 in total electricity. The water cost often exceeds the electricity cost. This is an appliance where per-use electricity is genuinely negligible.
