Pressure Washers

A pressure washer is a garden hose with discipline. It takes ordinary tap pressure, forces it through a narrow nozzle, and turns a chore that used to take a scrub brush and a Saturday into a job measured in minutes. The two numbers that matter are PSI, the force of the jet, and GPM, the volume of water behind it. Multiply them and you get cleaning units, a rough measure of how fast a machine strips grime. A car wash wants modest force and plenty of soap. A stained driveway wants both numbers high, and a long hose so the machine does not have to move every ten feet.

The twelve washers below split into three honest groups. Compact electrics from CRAFTSMAN, Karcher, Sun Joe and Westinghouse cover cars, patio furniture, fences and small patios on a household outlet, with no fuel, no oil and no pull cord. Mid-size electrics from Greenworks, DEWALT, CRAFTSMAN and Karcher add the pressure and flow for driveways, siding and second story reach while staying electric. Gas machines from Westinghouse and Simpson bring the flow rate that large concrete and heavy paint prep demand, at the cost of noise, fuel storage and winterizing. Every pick is sold on Amazon, and every PSI and GPM figure is the maker rating, with maximum and working figures kept separate where the maker separates them.
