Buying advice: pressure washers

  1. Electric suits most homes and is easy to store. Gas suits large areas, heavy grime and places without outlets.
  2. Around 1,500 to 2,000 PSI handles cars and patio furniture. 2,500 PSI and up suits concrete and stripping.
  3. Quick-connect nozzles from 0 to 40 degrees cover most jobs. Avoid the 0-degree nozzle on wood, siding and cars.
  4. Longer hoses reduce moving the machine. Don't use long extension cords with electric washers; use a longer hose instead.
  5. Gas washers need fuel stabilizer and winterizing. Electric washers need draining before freezing weather.

Where can I buy the Karcher K5 Premium Full Control Plus?

It's sold on Amazon. Prices and stock change often, so check the current listing before you buy, our link takes you straight to it.

What PSI is safe for washing a car?

1200 to 1900 PSI, held at least 12 to 18 inches from the paint with a wide 25 to 40-degree fan nozzle, is the generally recommended range for car exteriors. Every unit in this list can exceed that at full power, so the practical safety margin comes from nozzle choice and distance rather than the machine's peak PSI rating. Never use a 0-degree pinpoint nozzle on paint at close range, it can cut through clear coat.

Do I need a foam cannon for washing my car with a pressure washer?

Not strictly, but it helps. A foam cannon attachment mixes car soap with pressurized water into a thick foam that clings to the surface and lifts dirt before you touch it with a wash mitt, reducing the risk of dragging grit across the paint (the main cause of swirl marks). Most foam cannons attach via a standard quick-connect fitting, which the Sun Joe SPX3000, Karcher K5, and AR Blue Clean AR383 all support.
