This category covers electric and gas-powered pressure washers for home use, from light-duty models meant for patio furniture and cars to heavier machines built for siding, decks, and driveways.
We compare pressure (PSI) and flow rate (GPM) as published by the manufacturer, since the two figures together determine cleaning power more than either alone, and we weigh that against verified owner reports on hose length, wheel durability, and detergent tank design.
Gas pressure washers run a combustion engine and produce carbon monoxide. They are built for outdoor use only and should never run in a garage, shed, or other enclosed space, even with the door open. Electric models avoid that risk but are generally lower in pressure and flow.
